Abstract:

In this paper, we present a network function virtualization (NFV) architecture to deploy different virtualized network functions (VNF) on an optical transport network. NFV concepts do not only apply to data plane functions (i.e., packet processing or forwarding), but also to control plane functions, such as path computation. First, we focus on the IT and network resources that are virtualized to provide the required VNFs. Second, we provide an example of VNF on top of the virtualized infrastructure, by proposing a path computation element (PCE) architecture to deploy a PCE by means of NFV. The

Abstract:

Operators of networks are striving to provide functional network-based services, while keeping the cost of deploying the service to a minimum. Network Function Virtualization (NFV) is considered to be a promising model to modify such employment by separating network functions from the basic hardware properties, after which they are converted into the style of software. These are eventually referred to as Virtual Network Functions (VNFs). This separation offers numerous benefits, including the decrease of Capital Expenditure (CAPEX) and Operation Expense (OPEX), in addition to the enhanced elas

Abstract:

The abstraction of the network node functions using virtualization methods introduced an innovative architecture called Network Function Virtualization (NFV). In NFV, every virtualization software hosts a network service recognized as a Virtual Network Function (VNF). In general, the network provider creates a Service Function Chain (SFC) for every sequence of multiple requested VNFs by the customers. Although NFV allows for a more flexible and economical approach, it is more prone to error and failure. Therefore, providing reliable provisioning for VNF chaining is one of the key issues in NFV

Abstract:

<span lang="EN-US">Software defined network (SDN) and network function virtualization (NFV) are new paradigms and technologies of the network which support the best experience of providing functions and services, managing network traffic, and a new way of control. They support virtualization and separating data from control in network devices, as well as provide services in a software-based environment. Internet of things (IoT) is a heterogeneous network with a massive number of connected devices and objects. IoT should be integrated with such technologies for the purpose of providing th

Abstract:

Since ETSI introduced the architectural framework of network function virtualization (NFV), telecom operators have paid more attention to the synergy of NFV and cloud computing. With the integration of the NFV cloud platform, telecom operators decouple network functions from the dedicated hardware and run virtualized network functions (VNFs) on the cloud. However, virtualization degrades the performance of VNF, resulting in violating the performance requirements of the telecom industry. Most of the existing works were not conducted in a cloud computing environment, and fewer studies focused on

Abstract:

Future 5G networks will bring important challenges to network operators, such as the traffic load increase mainly due to the proliferation of mobile broadband communications. This will force mobile network operators (MNOs) redesigning and investing in their infrastructures [e.g., new equipment for radio access network (RAN), backhaul] to cope with such data growth. Aiming at lowering both capital expenditures and operational expenditures, current networking trends on network virtualization, software-defined networking (SDN), and network function virtualization (NFV) provide an appealing scenar

Abstract:

Abstract The demand for scalable, open and granular networks has enabled mobile networks such as 5G to adopt new concepts including NFV (Network Function Virtualization). NFV separates the dependency of network functions from the hardware component, allowing them to be deployed flexibly and dynamically across network slices. In this way, operators can deliver personalized services and optimize the use of network resources, contributing to greater operational efficiency and an enhanced end-user experience. However, there are several issues to be addressed, such as the security of VNFs and the w

Abstract:

Virtualization technology is slowly being used to build network infrastructure called Network Function Virtualization (NFV). It takes network functions such as firewall, load balancer, IPS out of its hardware then use its software to be run on high specification server. It helps reduce vendor lock-in and help create a multiplatform network function environment. It has a lot of benefits compared to a traditional network. One of them is it can reduce the number of hardware that is used in the telecom industry. This technology runs on the hypervisor that is used for the management of hardware. On

Abstract:

With the advancement of technology, virtualization has become very important for Information Technology (IT) experts. Network Functions Virtualization (NFV) means to address issues resulting from complex hardware-based appliances by developing standard IT virtualization technologies. Software Defined Networking (SDN) solidifies the advantages of datacenter virtualization, increases resource flexibility and utilization, and reduces infrastructure costs and overhead. Datacenter networks should have the ability to guarantee high throughput and resiliency. For such reasons, typical datacenter netw

Abstract:

Thanks to Software Defined Networking (SDN) and Network Functions Virtualization (NFV), the use and behaviour of interconnect network backhauls to provide virtualization services has changed completely. Several benefits have been discovered in various application areas that combine SDN and NFV. As a result, we explored the SDN / NFV paradigm to determine if network services could be efficiently deployed, managed, and distributed to end users. The Internet of Things (IoT) is inseparable from improving SDN / b NFV to improve this task. However, until now, problems related to Edge cloud communica

New trends and emerging requirements have driven the development of extensions to the path computation element (PCE) architecture beyond the computation of a set of constrained routes and associated resources between endpoints, given a network topology. Such extensions involve the use of a PCE for the control of network services, in which deploying a PCE as a centralized network controller facilitates the adoption of software-defined networking (SDN) principles while allowing a progressive migration of already existing deployments.

Abstract:

Network function virtualization (NFV) is a promising technique of high quality, flexible and scalable service for telecommunication companies clients and for enterprise data center clients. One of the important capabilities of this technique is providing a virtual service as a combination of multiple virtual functions. There are two types of virtual functions: those intended for a single customer (su-VF) and those that can serve multiple users (mu-VF). In case when output of mu-VF is chained with inputs of several different su-VFs, there is a need for a mechanism of identification and separati

The network function virtualization (NFV) feature lies at the core of modern networking, and it allows on-demand real-time integration of new network functions, which is a great benefit for large-scale infrastructure networks. In contrast to the functional benefits, NFV introduces software complexity and computational overhead through additional abstraction layers.
