Globalization is responsible for rapid development and release of information technologies. Globalization drives the competitiveness of people and organizations. Competitiveness makes organizations in particular to seek for solutions to enhance their competitive edge. Recent survey results on server virtualization suggest that the need to enhance competitiveness by reducing costs and improving business productivity is a major reason for the adoption of server virtualization in organizations. Thus, in taking adoption decisions on emerging technologies such as server virtualization, the provocative question we ask is: Is server virtualization implementation in business and public organizations a worthwhile investment? The outcomes of this study clearly show the answer is YES. However, the pitfalls associated with the implementation of these technologies are capable of making future adopters skeptical. This study examined the benefits and drawbacks of server virtualization implementation in 83 South African organizations. Server virtualization implementation has couple of drawbacks, which should be looked into.

Full textAbstract:
This article analyses the virtualization process of university courses implemented in the four schools of the National Distance Education University (UNED, for its acronym in Spanish). Primarily, the objective is to determine whether the virtualization of the courses should be the only alternative for students, or if it should be another tool to integrate into the pedagogic model of distance education in the context and reality of Costa Rica, in regards to the viability of access to digital technologies. Thus, an analysis of the Information and Communication Technologies (ICT) was done through virtualization and e-learning, explaining its implementation in UNED, a setting where there is still a long way to go in terms of accessibility, mainly between urban and rural areas. Additionally, the ICTs are approached as an alternative, an option, or a tool within the distance education model, since their implementation depends on a pedagogic foundation (techniques, strategies, and methodologies in ICT), and above all, on the context. The conclusions state that the virtualization of the courses must be an alternative but not an imposition for the students, because consideration of the context is vital, in terms of accessibility to digital technologies in Costa Rica, meaning that the quality of education must prevail over the means (semi-virtual, hybrid, virtual, or distance). Virtualization is not a matter of being at the forefront by means of technical innovation, but its implementation must be based on a real need with suitable conditions (adequate logistic infrastructure). Finally, ICTs must depend on a clearly established pedagogical curriculum, without reducing the access and quality in education.

A new approach to creating a cloud virtualization environment for the network infrastructure of educational institution has been proposed. It is based on the joint use of virtualization technologies and software-defined networks. Virtual network infrastructure is a combination of technologies and architectural solutions. It provides users with mobility during an ongoing educational process, secures access to cloud information resources of the wireless virtual network of an educational institution and centralized Internet access control. A prototype of the virtual network infrastructure of the Belarusian State University has been built. The prototype implements a model that includes virtual network segments (subnets), with which services are provided to end users, and virtual segments that provide presentation of service functions. Virtualization technologies and software-defined networks allow to unify the process of creating network infrastructure, to scale the resources provided on demand with minimal organizational and technical costs, and to adapt the virtual infrastructure to the requirements of a particular educational institution. The proposed model using virtual network segments has been implemented in the data processing center of the Belarusian State University. To create a cloud environment, the solution based on OpenStack was chosen. The basis of the virtualization environment is cloud services, which provide the implementation of the functionality of a virtual network infrastructure.

Cloud computing can improve corporate IT operational efficiency and reduce maintenance costs on enterprise PC terminal after centralizing computing and IT services. However, computing resources centralization makes security control and management particularly complicated. Without moderate isolation and security policy, one computer infected by virus can cause the whole network paralysis in cloud computing. It is absolutely necessary to develop "cloud management system" in cloud computing. In this paper, we analysis cloud management system architectures, build a cloud management system conceptual model, and design cloud management system deployment. We also implement cloud management system integrating a variety of technologies including host virtualization technology, virtual host automatic backup management, virtual host blocking and audit technique, and cloud computing access control etc. The cloud management system can guarantee the security of cloud computing, and provide a more economical and more reasonable solution to the cloud service users.

Fourth-Generation (4G) mobile networks are based on Long-Term Evolution (LTE) technologies and are being deployed worldwide, while research on further evolution towards the Fifth Generation (5G) has been recently initiated. 5G will be featured with advanced network infrastructure sharing capabilities among different operators. Therefore, an open-source implementation of 4G/5G networks with this capability is crucial to enable early research in this area. The main contribution of this paper is the design and implementation of such a 4G/5G open-source testbed to investigate multioperator infrastructure sharing capabilities executed in virtual architectures. The proposed design and implementation enable the virtualization and sharing of some of the components of the LTE architecture. A testbed has been implemented and validated with intensive empirical experiments conducted to validate the suitability of virtualizing LTE components in virtual infrastructures (i.e., infrastructures with multitenancy sharing capabilities). The impact of the proposed technologies can lead to significant saving of both capital and operational costs for mobile telecommunication operators.

Internet has played an important part in the success of information technologies. With the growing and changing demands, there are many limitations faced by current Internet. A number of network testbeds are created for solving a set of specific problems in Internet. Traditionally, these testbeds are lacking of large scale network and flexibility. Therefore, it is necessary to design and implement a testbed which can support wide range of experiments and has the ability of programmable network. Besides, there has been a big change enabled by cloud computing in recent years. Although networking technologies have lagged behind the advances in server virtualization, the networking is still an importance component to interconnect among virtual machines. There are also measurement issues with growing number of virtual machines in the same host. Therefore, we also propose integrating management functions of virtual network in our testbed. In this paper, we design and create a Future Internet testbed in Taiwan over TWAREN Research Network. This testbed evolves into an environment for programmable network and cloud computing. This paper also presents several finished and ongoing experiments on the testbed for multiple aspects including topology discovery, multimedia streaming, and virtual network integration. We will continue to extend our testbed and propose innovative applications for the next generation Internet.

Abstract This paper introduces CAAI, a novel cognitive architecture for artificial intelligence in cyber-physical production systems. The goal of the architecture is to reduce the implementation effort for the usage of artificial intelligence algorithms. The core of the CAAI is a cognitive module that processes the user’s declarative goals, selects suitable models and algorithms, and creates a configuration for the execution of a processing pipeline on a big data platform. Constant observation and evaluation against performance criteria assess the performance of pipelines for many and different use cases. Based on these evaluations, the pipelines are automatically adapted if necessary. The modular design with well-defined interfaces enables the reusability and extensibility of pipeline components. A big data platform implements this modular design supported by technologies such as Docker, Kubernetes, and Kafka for virtualization and orchestration of the individual components and their communication. The implementation of the architecture is evaluated using a real-world use case. The prototypic implementation is accessible on GitHub and contains a demonstration.

The fifth generation (5G) of cellular networks promises to be a major step in the evolution of wireless technology. 5G is planned to be used in a very broad set of application scenarios. These scenarios have strict heterogeneous requirements that will be accomplished by enhancements on the radio access network and a collection of innovative wireless technologies. Softwarization technologies, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), will play a key role in integrating these different technologies. Network slicing emerges as a cost-efficient solution for the implementation of the diverse 5G requirements and verticals. The 5G radio access and core networks will be based on a SDN/NFV infrastructure, which will be able to orchestrate the resources and control the network in order to efficiently and flexibly and with scalability provide network services. In this paper, we present the up-to-date status of the software-defined 5G radio access and core networks and a broad range of future research challenges on the orchestration and control aspects.

The implementation of NFV allows improving the flexibility, efficiency, and manageability of networks by leveraging virtualization and cloud computing technologies to deploy computer networks. The implementation of autonomic management and supervised algorithms from Machine Learning [ML] become a key strategy to manage this hidden traffic. In this work, we focus on analyzing the traffic features of NFV-based networks while performing a benchmarking of the behavior of supervised ML algorithms, namely J48, Naïve Bayes, and Bayes Net, in the IP traffic classification regarding their efficiency; considering that such an efficiency is related to the trade-off between time-response and precision. We used two test scenarios (an NFV-based SDN and an NFV-based LTE EPC). The benchmarking results reveal that the Naïve Bayes and Bayes Net algorithms achieve the best performance in traffic classification. In particular, their performance corroborates a good trade-off between precision and time-response, with precision values higher than 80 % and 96 %, respectively, in times less than 1,5 sec.

The paper is devoted to the practical implementation aspects of a software-defined mobile network based on the Cloud-RAN architecture and universal software radio peripheral National Instruments USRP 2900. We propose a multilayer network architecture, which consists of a radio access network (RAN) plane, a core plane, a control plane, an artificial intelligence (AI) plane, and a monitoring system that collects data about network performance. The RAN plane provides all functions related to channel scheduling, data encoding and signal processing and combines all macro and small cells, as well as Wi-Fi access points. The core plane provides functionality of the evolved packet core such as service and packet gateways, mobility management entities and edge routers. The control plane is responsible for load balancing over all cells, spectrum sharing, spectrum reallocation, infrastructure reconfiguration, and other management parameters. The AI plane is responsible for inference and decisions making about optimal network configuration taking into account instantaneous network conditions. Such decisions are supported by a set of machine learning models, which are trained over the available statistics, collected through a long-term period of network operation. External monitoring system provides the needed data for AI plane by using the MQTT (Message Queue Telemetry Transport) protocol to collect information from all base stations, Wi-Fi access points and mobile devices.The proposed system enables the logical network slicing into multiple isolated segments over a single physical infrastructure by using virtualization of radio resources. A new method of intelligent radio resource management is proposed to improve the efficiency of spectrum utilization by predicting traffic demand of particular network sliced using deep recurrent neural network. Simulation results show that for the case of network slicing the proposed method allows to double the capacity of the physical network infrastructure, while ensuring the target quality of service for all users.

This should represent the virtual counterpart of the IoT users with the ultimate goal of: (i) avoiding the user from having the burden of following the tedious processes of setting, configuring and updating IoT services the user is involved in; (ii) acting on behalf of the user when basic operations are required; (iii) exploiting to the best of its ability the IoT potentialities, always taking always account the user profile and interests. Accordingly, the VU is a complex representation of the user and acts as a proxy in between the virtual objects and IoT services and application; to this, it includes the following major functionalities: user profiling, authorization management, quality of experience modeling and management, social networking and context management. In this respect, the major contributions of this paper are to: provide the definition of VU, present the major functionalities, discuss the legal issues related to its introduction, provide some implementation details, and analyze key performance aspects in terms of the capability of the VU to correctly identify the user profile and context.

The information technology sector has experienced phenomenal growth during recent years. To follow this development many new technologies have emerged to satisfy the expectations of businesses and customers, such as Cloud Computing, mobility, virtualization, Internet of things and big data. Traditional network cannot longer support this growth and suffers more and more in terms of misconfiguration,management and configurations complexity. Software defined network (SDN) architectures can be considered as a big revolution in the field of computer networks, because they offer a centralized control on infrastructure, services and the applications deployed which facilitate configuration and management on the network. The implementation of this type of architecture is not obvious and requires great expertise and good handling and management of network equipment. To remedy this problem the SDN architectures have evolved towards distributed and hybrid architectures. Despites the advantages of using SDN, security issues remain a real obstacle in front of the deployment of this type of architecture. The centralized architecture of this type of networks makes it vulnerable to several types of attacks and intrusions, and the implementation of security equipment generally causes a decrease in performance and increase latency.

Abstract This article focuses on a multiple source prioritization and validation service. We describe a modern rule-based, loosely coupled solution. We follow generalization, efficiency and agility principles in application design. We show benefits and stumbling blocks in micro-service architectural style and in rule-based solutions, where even the selection task is solved through selection rules, which encapsulate the calls to Entity Services, allowing access to input-sources. We allowing the rule-based service efficiency and further local and remote input data selection scenarios for the validation Statistical Service. In particular, data virtualization technologies enable architects to use remote sourcing and further increases agility in data selection issues. Through a wide number of experimental results, we show the necessary level of attention in process implementation, data architectures and resource usage. Agility and efficiency emerge as drivers which possibly sustain the Modernization flexibility impetus. In fact, flexible services may potentially serve multiple scenarios and domains.

Network latency will be a critical performance metric for the Fifth Generation (5G) networks expected to be fully rolled out in 2020 through the IMT-2020 project. The multi-user multiple-input multiple-output (MU-MIMO) technology is a key enabler for the 5G massive connectivity criterion, especially from the massive densification perspective. Naturally, it appears that 5G MU-MIMO will face a daunting task to achieve an end-to-end 1 ms ultra-low latency budget if traditional network set-ups criteria are strictly adhered to. Moreover, 5G latency will have added dimensions of scalability and flexibility compared to prior existing deployed technologies. The scalability dimension caters for meeting rapid demand as new applications evolve. While flexibility complements the scalability dimension by investigating novel non-stacked protocol architecture. The goal of this review paper is to deploy ultra-low latency reduction framework for 5G communications considering flexibility and scalability. The Four (4) C framework consisting of cost, complexity, cross-layer and computing is hereby analyzed and discussed. The Four (4) C framework discusses several emerging new technologies of software defined network (SDN), network function virtualization (NFV) and fog networking. This review paper will contribute significantly towards the future implementation of flexible and high capacity ultra-low latency 5G communications.

Traditionally, the recognition of sound mainly focuses on the source of sound, such as level and quality. Now, the sound, the environment, and the listeners have begun to study the landscape structure, composition, and characteristics of the acoustic environment. The purpose of this paper is to study the simulation design of virtual reality voice landscape quantification based on cloud computing. Firstly, the definition and characteristics of cloud computing are described, and the key technologies of cloud computing are analyzed. Combined with the basic principles of technology selection, the virtualization technology is emphatically analyzed. By selecting 7 acoustic elements, such as traffic sound, water flow sound, fountain sound, birdsong, wind sound, rippling sound, beach sound, and seabird sound, the possible acoustic elements in a given park environment are simulated for subjective evaluation. The experimental results show that when the traffic sound is 60 dB, the evaluation result of the superimposed sound type is the same as that when the traffic sound is 50 dB. For the superimposed sound level, 30 dB and 40 dB are significantly different from 60 dB and 70 dB, respectively, 50 dB is only significantly different from 70 dB, while 60 dB is only not significantly different from 50 dB, and 70 dB evaluation is significantly different from each sound level. However, 60 dB can be regarded as the turning point of the evaluation result. When the sound level of the added sound is greater than 60 dB, the evaluation result is obviously worse.

Abstract: The deployment of 5G mobile communication networks is just getting started right now. There are numerous technologies available today, each capable of fulfilling activities such as enabling voice traffic via voice over IP (VoIP), providing broadband data access in mobile environments, and so on. However, there is a pressing need to implement technology that can bring all of these systems together into a single unified system. Because it is all about smoothly integrating terminals, networks, and applications, 8G presents a solution to this dilemma. In this work, an attempt is made to provide a study of various cellular technologies, such as 4G, 5G, 6G, 7G, and FG, as well as a detailed comparison between them. With the introduction of network virtualization and the implementation of 5G/IoT, mobile networks will become more complicated and offer more diverse services. This raises concerns about a considerable increase in the workload of network operations. Meanwhile, artificial intelligence (AI) is advancing rapidly and is projected to alleviate human resource shortages in a variety of industries. Similarly, the mobile industry is gaining traction in the application of artificial intelligence (AI) to network operations in order to improve the efficiency of mobile network operations. This paper will address the idea of using AI technology to network operations and will give various use examples to demonstrate that AI-driven network operations have a bright future.

Emerging network services and subsequent growth in the networking infrastructure have gained tremendous momentum in recent years. Application performance requiring rapid real-time network provisioning, optimized traffic management, and virtualization of shared resources has induced the conceptualization and adoption of new networking models. Software defined networking (SDN), one of the predominant and relatively new networking paradigms, seeks to simplify network management by decoupling network control logic from the underlying hardware and introduces real-time network programmability enabling innovation. The present work reviews the state of the art in software defined networking providing a historical perspective on complementary technologies in network programmability and the inherent shortcomings which paved the way for SDN. The SDN architecture is discussed along with popular protocols, platforms, and existing simulation and debugging solutions. Furthermore, a detailed analysis is presented around recent SDN development and deployment avenues ranging from mobile communications and data centers to campus networks and residential environments. The review concludes by highlighting implementation challenges and subsequent research directions being pursued in academia and industry to address issues related to application performance, control plane scalability and design, security, and interdomain connectivity in the context of SDN.

Full textAbstract:
Wireless Sensor Networks (WSNs) have a wide range of applications scenarios in computer vision, from pedestrian detection to robotic visual navigation. In response to the growing visual data services in WSNs, we propose a proactive caching strategy based on Stacked Sparse Autoencoder (SSAE) to predict content popularity (PCDS2AW). Firstly, based on Software Defined Network (SDN) and Network Function Virtualization (NFV) technologies, a distributed deep learning network SSAE is constructed in the sink nodes and control nodes of the WSN network. Then, the SSAE network structure parameters and network model parameters are optimized through training. The proactive cache strategy implementation procedure is divided into four steps. (1) The SDN controller is responsible for dynamically collecting user request data package information in the WSNs network. (2) The SSAEs predicts the packet popularity based on the SDN controller obtaining user request data. (3) The SDN controller generates a corresponding proactive cache strategy according to the popularity prediction result. (4) Implement the proactive caching strategy at the WSNs cache node. In the simulation, we compare the influence of spatiotemporal data on the SSAE network structure. Compared with the classic caching strategy Hash + LRU, Betw + LRU, and classic prediction algorithms SVM and BPNN, the proposed PCDS2AW proactive caching strategy can significantly improve WSN performance.

The formation of the digital economy in the world is due to the development of a number of new breakthrough technologies that are unfolding in the process of the Fourth Industrial Revolution. The basic of them is the fifth generation of mobile communication (5G), which provides the opportunity to implement a large number of new information and communication technologies, as well as hardware solutions and products for the economy and society. Countries that take the leadership in building 5G infrastructure and adopting fifth-generation mobile standards will be able to apply their successful expertise to deploy a new generation of communications in other countries, opening up ample opportunities to enhance technological, economic and geopolitical impact on them. The paper is devoted to the analysis of trends in the formation and development of mobile technologies of the fifth generation in the world and its impact on the processes of digitalization of the economy, as well as the identification of promising practices for their implementation in Ukraine. In the course of the analysis, it is defined that 5G, unlike the previous generations of communication, is peculiar to large-scale virtualization, which goes beyond exclusively hardware and infrastructural decisions, and the majority of its functionality is realized by a software way. That is why it is often called not a network, but a system or platform that enables the implementation of a significant number of services and solutions, in particular: high-speed data transmission, a wide range of Internet of Things services, storing large data sets in cloud storage, virtual reality services, smart automation and robotics of production, unmanned vehicles, etc. But 5G is also characterized by a number of shortcomings (due to the use of short radio waves with rapid attenuation) that actualize the challenges, associated with increasing consumption of raw materials and energy, increased anthropogenic burden, lack of study of this technology’s potential negative impact on human health and local ecosystems etc. It is defined, that 5G-technologies, being a new event, according to the concept of technology life cycle are in the lower part of the S-shaped technological curve. This stage of technology development is characterized by significant financial investments and small economic returns, associated primarily with sales of radio frequency resources. Measures are proposed to avoid in the future for Ukraine the role of a raw material appendage of technologically developed countries, in terms of creating a favorable national institutional environment and ensuring support and encouragement of the development of new digital communication technologies.

In the article, the authors consider the risks in the space of the life world in the aspect of digitalization. By digitalization, they understand the socialization of digital technologies and the construction of systems of social relations based on them. Discreteness, rapid changes and increased risk-taking distinguish the human life world of digital society. Subjective perception of reality in the space of an individual’s life world in a digital environment increases the risks of the emergence and implementation of communication strategies of behavior that negatively affect the relationship of a person with the surrounding world. The presence of a person in the digital environment not only makes him vulnerable to risks, but also prevents the recognition of risk situations, as well as leads to rejection and ignoring of risks. The individual perceives the digital space as a favorable environment. The degree of trust in the digital world for a person is much higher than the trust in the space of material objects that represent a certain danger in the individual’s mind. The individual represents the digital environment as a conflict-free space that protects a person from threats and challenges. Axiological changes in modern society have caused the emergence of risks of digitalization in the space of the life world. In the digital space, an individual sees risk as a value. The space of the life world in the digital environment becomes virtual. Virtualization of human existence contributes to the formation of a sense of trust in the world, it makes the constant improvement of their situation the motive of their life, which is possible through the acceptance of risk and responsibility for their actions. An individual perceives risk as an opportunity for freedom of choice of solutions, freedom to find ways out of constructed situations. A person in virtual space does not consider risks as dangerous, since they are a necessary condition for the existence of a digital environment. The individual presents the digital life world as less risky, which contributes to an ever deeper immersion in it and generates the risk of virtualization of being.

Full textAbstract:
Health 4.0 is an extension of the Industry standard 4.0 which is aimed at the virtualization of health-care services. It employs core technologies and services for integrated management of electronic health records (EHRs), captured through various sensors. The EHR is processed and transmitted to distant experts for better diagnosis and improved healthcare delivery. However, for the successful implementation of Heath 4.0 many challenges do exist. One of the critical issues that needs attention is the security of EHRs in smart health systems. In this work, we have developed a new interpolation scheme capable of providing better quality cover media and supporting reversible EHR embedding. The scheme provides a double layer of security to the EHR by firstly using hyperchaos to encrypt the EHR. The encrypted EHR is reversibly embedded in the cover images produced by the proposed interpolation scheme. The proposed interpolation module has been found to provide better quality interpolated images. The proposed system provides an average peak signal to noise ratio (PSNR) of 52.38 dB for a high payload of 0.75 bits per pixel. In addition to embedding EHR, a fragile watermark (WM) is also encrypted using the hyperchaos embedded into the cover image for tamper detection and authentication of the received EHR. Experimental investigations reveal that our scheme provides improved performance for high contrast medical images (MI) when compared to various techniques for evaluation parameters like imperceptibility, reversibility, payload, and computational complexity. Given the attributes of the scheme, it can be used for enhancing the security of EHR in health 4.0.

Background Health care systems are currently undergoing a digital transformation that has been primarily triggered by emerging technologies, such as artificial intelligence, the Internet of Things, 5G, blockchain, and the digital representation of patients using (mobile) sensor devices. One of the results of this transformation is the gradual virtualization of care. Irrespective of the care environment, trust between caregivers and patients is essential for achieving favorable health outcomes. Given the many breaches of information security and patient safety, today’s health information system portfolios do not suffice as infrastructure for establishing and maintaining trust in virtual care environments. Objective This study aims to establish a theoretical foundation for a complex health care system intervention that aims to exploit a cryptographically secured infrastructure for establishing and maintaining trust in virtualized care environments and, based on this theoretical foundation, present a proof of concept that fulfills the necessary requirements. Methods This work applies the following framework for the design and evaluation of complex intervention research within health care: a review of the literature and expert consultation for technology forecasting. A proof of concept was developed by following the principles of design science and requirements engineering. Results This study determined and defined the crucial functional and nonfunctional requirements and principles for enhancing trust between caregivers and patients within a virtualized health care environment. The cornerstone of our architecture is an approach that uses blockchain technology. The proposed decentralized system offers an innovative governance structure for a novel trust model. The presented theoretical design principles are supported by a concrete implementation of an Ethereum-based platform called VerifyMed. Conclusions A service for enhancing trust in a virtualized health care environment that is built on a public blockchain has a high fit for purpose in Healthcare 4.0.

Full textAbstract:
The article presents a conceptual analysis of the intercultural model of development of modern cities, with an emphasis on the selection strategy and activity of axiological approach to developing models of modernization of a modern city, marked specific features of urban culture - multicultural, multipolarity interests, values, needs and opportunities for groups. Revealed that about the virtualization of the social space and the introduction of information and communication technologies, which express a qualitative difference between the interaction of the urban population as a unit of sociocultural stratification of the culture of a particular regional community, are determined by particularly significant factors influencing the formation of the modern sociocultural space of a multi-ethnic city. The tendencies of participation in the formation of the sociocultural space of Ukrainian cities by wide circles of the public with the active and consistent participation of citizens in exercising control over cultural policy are characterized and organizational conditions for sustained feedback from the public and authorities. The theoretical and methodological foundations of the practice of sociological support of the development processes of multi-ethnic Ukrainian urban communities in the context of the implementation of the European intercultural strategy are considered. The emphasis is on solving the problems of a sociological study of the needs of the urban community in the information environment and the complication of sociocultural relationships between the subjects of the processes of modernization of the cultural urban environment. The need for a systematic combination of sociological approaches based on the integration of the concepts of the city’s public space, the resource concept of the city, the concept of socialization, the socio-cultural capital of the city, the concepts of sociocultural identification and urban identity is stated. The author 's case was the conclusion that the processes of maintenance practices for the development of multi-ethnic Ukrainian urban communities in the context of the European strategy for intercultural indicate significant prospects of sociological studies of social and cultural development of the Ukrainian regional multicultural cities. The article emphasizes that the following areas are relevant: the development of research criteria for potentially productive sectors of the development of the sociocultural urban environment and the factors of activation of interested social groups in the context of the implementation of strategies and objectives of the concept of interculturalism.

Full textAbstract:
Background. The implementation of the new modern services on existing networks requires replacement or modernization of the old equipment. This negatively affects the efficiency of providing users with new types of services and their cost. Therefore, the issues/tasks of implementing SDN technology in the construction of networks are in the center of attention of representatives of science-research organizations and telecom operators. SDN networks have the advantages of flexible scaling of the system without replacing existing server and network equipment, eliminating operator dependence on specific vendor solutions, and rapid implementation of the new network technologies and services. To determine the numerical values of indicators of the functioning of SDN networks and check their compliance with the requirements, it is proposed to use in working process simulation modelling. For these goals, the Open Networking Foundation consortium developed the Mininet network emulator, the elements of that are published publicly. The formation of the simulation model and the procedure for determining the performance indicators of the SDN network that uses Mininet has a number of features that are considered in the work.
Objective. The purpose of the article is to build a simulation model based on the Mininet network emulator and to determine the performance indicators of SDN networks of various structures/topologies.
Methods. Creation of a SDN network segment for testing process of its functioning in the overload mode of various communication routes.
Results. The Mininet network emulator allows simulating SDN networks of a rather complex structure, change the performance of network branches and the amount of load in communication routes, to create a network-wide overload mode. During the simulation, it is possible to determine a number of indicators of network performance, such as the RTT (Round Trip Time) parameter for each route of communication, the bandwidth of branches and routes of communication, the amount of delay on network elements, loading of OpenFlow Switch ports/interfaces, network elements with the highest delay, the number of served and lost packets.
Conclusions. Use of the Mininet network emulator is a fairly convenient tool for determining the performance indicators of SDN networks. However, there are also some problems. First of all, setting up the system's operability requires writing programs to ensure the interaction among standard elements from the Mininet library. Secondone, is when congestion occurs in the communication routes, the Floodlight Controller does not automatically balance traffic along the work-around route. This task has to be solved manually by making changes to the OpenFlow Switch routing tables.
