Abstract:
Reliability, survivability, and stability analysis tasks are typical not only for telecommunications, but also for systems whose components are subject to one or more types of failures, such as transport, power, mechanical systems, integrated circuits, and even software. The logical approach involves the decomposition of the system into a number of small functional elements, and within telecommunications networks they are usually separate network devices (switches, routers, terminals, etc.), as well as communication lines between them (copper-core, fiber-optic, coaxial cables, wireless media, and other transmission media). Functional relationships also define logical relationships between the failures of individual elements and the failure of the network as a whole. The assumption is also used that device failures are relatively less likely than communication line failures, which implies using the assumption of absolute stability (reliability, survivability) of these devices. Model of a telecommunication network in the form of the generalized model of Erdos–Renyi is presented. In the context of the stability of the telecommunications network, the analyzed property is understood as the connectivity of the network in one form or another. Based on the concept of stochastic connectivity of a network, as the correspondence of a random graph of the connectivity property between a given set of vertices, three connectivity measures are traditionally distinguished: two-pole, multi-pole, and all-pole. The procedures for forming an arbitrary structure of sets of paths and trees for networks are presented, as well as their generalization of multipolar trees. It is noted that multipolar trees are the most common concept of relatively simple chains and spanning trees. Solving such problems will allow us to proceed to calculating the probability of connectivity of graphs for various connectivity measures.

Abstract:
The article formulates the main tasks of management of information networks and telecommunications services in terms of ensuring their reliable operation. The telecommunication network is considered as a complex system consisting of many components, each of which has its own characteristics of operation during operation. The main functions of the telecommunication network control system are determined: fault detection and network status diagnostics, network device administration, forecasting and elimination of congestion and other possible deviations in network functioning, ensuring coordinated interaction between different types of control systems for providing telecommunication services with specified quality. Methods of analysis and management of networks are essentially a kind of identification methods, i.e. the current assessment of the parameters and condition of complex technical systems. There is a close relationship between identification and diagnostic tasks. The methods for solving these problems largely depend on the class to which the identification object can be assigned. Computer and telecommunication networks belong to the class of distributed systems with delays in signal and control information. Methods of retrospective identification are used to analyze the state of such systems. The influence of delays of signal and control information on the efficiency of search and determination of places of failures, overloads and emergency modes in communication networks is investigated. The results of computer simulation are given. The approach based on regular control of parameters and condition of network nodes taking into account delays of receipt of information on parameters and a condition of a concrete network node and delays of the control information necessary for adjustment of parameters of a network node as control object has found further development.

Abstract:
Telecommunication networks are vulnerable towards single or simultaneous nodes/links failures, which may lead to the disruption of network areas. The failures may cause performance degradation, reduced quality of services, reduced nodes/links survivability, stability, and reliability. Therefore, it is important to measure and enhance the network robustness, via the use of robustness metrics. This paper gives an overview of several robustness metrics that are commonly used for optical networks, from the structural, centrality and functional perspectives.

Abstract:
Telecommunication systems generally performed better than other lifelines in the Christchurch-area earthquake sequence of 2010–2011; however, various service interruptions were a major concern for subscribers. Power disruption was the primary reason for service interruption in Christchurch, as has been similarly observed in many other major earthquakes around the world. Extensive ground failures impacted underground cabling, while Central Offices (COs) sustained minor damage due to strong shaking. Closure of the Central Business District and increased call volumes created additional strain on telecommunication service providers to deal with emergency response. This paper presents the findings of the post-earthquake lifeline performance investigations of both the landline network and the cellular network. Voice and data services of these networks are examined and commented based on the findings. The authors’ view of rendering the telecommunication systems more resilient is presented ( Eidinger and Tang 2014 ).

Abstract:
The European Telecommunications Standards Institute (ETSI) recommends that IP-telephony networks be divided into four classes according to the quality of service (quality of network services) QoS, the main indicator of which is packet delay (Y.1541). ITU-T Recommendation G.114 for public switched telephone networks provides delays close to ETSI gradations that correspond to different types of communication. The quality of the service from the user's point of view can be expressed by a set of indicators. These metrics are described in terms that are understandable to both the user and the service, and are independent of the network structure. Quality of service indicators are focused primarily on the effect perceived by the user, must be guaranteed to the user by the service and be objectively measured at the point of access to the service (ITU-T Recommendation I.350). ITU-T Recommendation E.862 provides possible approaches to accounting for the economic losses of the operator (in planning, design, operation and telecommunication network) and the user associated with technical failures. Operators of networks, working in market conditions, are interested in assessing possible losses due to failures and in comparing them with the costs of increasing the reliability of their funds.

Abstract:
Interconnection between telecommunication networks and other critical infrastructures is usually established through nodes that are spatially close, generating a geographical interdependency. Previous work has shown that in general, geographically interdependent networks are more robust with respect to cascading failures when the interconnection radius (r) is large. However, to obtain a more realistic model, the allocation of interlinks in geographically interdependent networks should consider other factors. In this paper, an enhanced interconnection model for geographically interdependent networks is presented. The model proposed introduces a new strategy for interconnecting nodes between two geographical networks by limiting the number of interlinks. Results have shown that the model yields promising results to maintain an acceptable level in network robustness under cascading failures with a decrease in the number of interlinks.

Abstract:
Abstract The main task of the clocking network synchronization (CNS) network subsystem is the formation, transmission, distribution and delivery of synchronization signals to the telecommunication system (TCS) digital equipment for the purpose of its coordinated interaction. Indicators of the telecommunication services quality are inextricably linked with the indicators of the CNS network functioning quality, in this regard, the process of monitoring and managing the CNS network comes to the fore for the purpose of prompt detection of failures and their subsequent elimination. The article provides an overview of the main classes of CNS network equipment and their diagnostic parameters, and also indicates the significant influence of the CNS network functioning process on the entire TCS functioning. To assess the technical condition of the CNS network an approach using the entropy analysis of the diagnostic parameters of the CNS network elements is proposed. The entropy model of the network dynamics is obtained in CNS work, which can later be used to develop a methodology for monitoring the technical condition of the CNS network. Using this model, it is possible to estimate not only the differential entropy of each CNS network element, but also to estimate the differential entropy of the entire CNS network or a separate fragment of the CNS network. Differential entropy parameters reflect the technical state of the CNS network.

Abstract:
Andhra Pradesh (AP) is one of the most vulnerable States in India to natural disasters such as cyclones, high rainfall and flooding. With a second-longest coastline of 975km, atleast one cyclone hits every year, mainly during October and November. Although the AP Government is taking preventive measures to reduce the loss of lives, the increase in economic loss due to the damage to critical infrastructure has become a point of worry. Power and telecom industries are interlinked; power loss or failure may disrupt the entire telecommunication network. This study examines the impact of cyclones on the telecom industry in AP coastal zones during the last two decades, considering it to be the most vital of all infrastructure systems. This study also discusses the measures that need to be taken by telecom service providers (TSPs) to build robust networks, provide redundancy during network element failures and resource management during network overload. To safeguard the people and assets, State Governments must ensure that their infrastructure systems conform to specific standards of quality and reliability. These standards should, however, be revised regularly and applied consistently.

Abstract:
The goal of this work is to design a minimum cost resilient overlay network, where a data network is on top of a transport network. Two major challenges are addressed. On one hand, a single failure in the transport network causes multiple simultaneous failures; on the other, the multicommodity flow must respect integrality. An integer programming formulation is presented to design an overlay, meeting the previous constraints. We prove the problem belongs to the class NP-Hard. Then, a decomposition approach is introduced, where the problem is solved in two steps by means of relaxations of the original formulation. Experiments carried out with real-life instances, coming from the Uruguayan telecommunication operator, show that the approach is competitive with respect to previous metaheuristics, to know, Tabu-Search (TS) and Variable Neighborhood Search (VNS). A modest percentage of cost-reduction is achieved in some instances, which means millionaire savings in practice.

Abstract:
The problem of stability analysis and its components of reliability and survivability is quite popular both in the field of telecommunications and in other industries involved in the development and operation of complex networks. The most suitable network model for this type of problem is a model that uses the postulates of graph theory. At the same time, the assumption of the random nature of failures of individual links of the telecommunications network allows it to be considered in the form of a generalized Erdos–Renyi model. It is well known that the probability of failure of elements can be interpreted in the form of a readiness coefficient and an operational readiness coefficient, as well as in the form of other indicators that characterize the performance of elements of a telecommunications network. Most approaches consider only the case of bipolar connectivity, when it is necessary to ensure the interaction of two end destinations. In modern telecommunications networks, services such as virtual private networks come to the fore, for which multipoint connections are organized that do not fit into the concept of bipolar connectivity. In this regard, we propose to extend this approach to the analysis of multi-pole and all-pole connections. The approach for two-pole connectivity is based on a method that uses the connectivity matrix as a basis, and, in fact, assumes a sequential search of all combinations of vertex sections, starting from the source and drain. This method leads to the inclusion of non-minimal cross-sections in the general composition, which required the introduction of an additional procedure for checking the added cross-section for non-excess. The approach for all-pole connectivity is based on a method that uses the connectivity matrix as a basis, and, in fact, assumes a sequential search of all combinations of vertex sections, not including one of the vertices considered terminal. A simpler solution was to control the added section for uniqueness. The approach for multipolar connectivity is similar to that used in the formation of the set of minimal all-pole sections and differs only in the procedure for selecting the combinations used to form the cross-section matrix, of which only those containing pole vertices are preserved. As a test communication network, the Rostelecom backbone network is used, deployed to form flows in the direction of "Europe-Asia". It is shown that multipolar sections are the most general concept with respect to two-pole and all-pole sections. despite the possibility of such a generalization, in practical applications it is advisable to consider particular cases due to their lower computational complexity.

ENGLISH ABSTRACT: Since 2002 data tra c has overtaken voice tra c in volume [1]. Telecom / Network operators still generate most of their income carrying voice tra c. There is however a huge revenue potential in delivering reliable guaranteed data services. Network survivability and recovery from network failures are integral to network reliability. Due to the nature of the Internet, recovery from link failures needs to be distributed and dynamic in order to be scalable. Link failure recovery schemes are evaluated in terms of the survivability of the network, the optimal use of network resources, scalability, and the recovery time of such schemes. The need for recovery time to be improved is highlighted by real-time data tra c such as VoIP and video services carried over the Internet. The goal of this thesis is to examine existing link failure recovery schemes and evaluate the need for their extension, and to evaluate the performance of the proposed link failure recovery schemes. i

Abstract:
In this thesis we examine mathematical models for dynamical reconfiguration of telecommunication networks. Dynamical configuration is one of the most important problems in the field of network management. In the case of some part of the network being damaged the system should maintain its operations, taking into account the new conditions. This can be achieved by using the residual capacity of the system if it is available. If there were not enough residual capacity, the managers of the system need to involve some of the unaffected traffic in order to reorganize traffic. A prolonged breakdown will push some customers to change their provider; there is also a lost [sic] of profit because of breakdowns, that can be considered as a certain implicit penalty. To reorganize traffic by using new routes we should have a flexible routing system.

Abstract:
Power transmission grid infrastructures deliver electricity across large distance and are vital to the functioning of modern society. Increasingly these setups embody highly-coupled cyber-physical systems where advanced telecommunications networks are used to send status and control information to operate power transmission grid components, i.e., "smart grids". However, due to the high inter-dependency between the communication and power grid network layers, failure events can lead to further loss of control of key grid components, i.e., even if they are undamaged. In turn, such dependencies can exacerbate cascading failures and lead to larger electricity blackouts, particularly under disaster conditions. As a result, a range of studies have looked at modelling failures in interdependent smart grids. However most of these designs have not considered the use of proactive network-level survivability schemes. Indeed, these strategies can help maintain vital control connectivity during failures and potentially lead to reduced outages. Hence this thesis addresses this critical area and applies connection protection methodologies to reduce communication/control disruption in transmission grids. The performance of these schemes is then analyzed using detailed simulation for a sample IEEE transmission grid. Overall findings show a good reduction in the number of overloaded transmission lines when applying network-level recovery schemes.

O crescimento do tráfego nas redes de telecomunicações por serviços de banda larga, telefonia fixa e móvel tem demandado esforços no planejamento e estudo da recomposição da rede, em especial redes de transporte, tornando elevado o nível de complexidade na elaboração de projetos que envolvem redes. A complexidade de interligação aumenta de acordo com as restrições impostas pela capacidade de investimentos e custos operacionais na obtenção da solução ótima para a melhor topologia de rede. Para resolver problemas de planejamento e recomposição da rede de telecomunicações é necessária a utilização de recurso computacional, pois problemas que envolvem redes desta natureza possuem a característica do conjunto de problemas de otimização combinatória, considerados difíceis. Com o objetivo de planejar e realizar estudos na recomposição da rede de telecomunicações, neste trabalho é apresentada a estratégia que visa o uso de recursos heurísticos como algoritmo genético e Dijkstra, bem como o conceito de rede fictícia na modelagem e solução computacional na obtenção da solução ótima referente à topologia de rede, possibilitando a análise prévia do tráfego na topologia proposta caso houver a incidência de falhas.

The interconnection complexity increases with the restrictions imposed by the capacity of investment and operating costs in obtaining the optimal solution for the best network topology. To resolve issues of planning and rebuilding of the telecommunication networks is necessary to use computational resources, since problems involving networks of this nature have the feature set of combinatorial optimization problems, considered difficult.

Abstract:
The evolution of wireless communication and circuit technology has enabled the development of an infrastructure consists of sensing, computation and communication units that makes administrator capable to observe and react to a phenomena in a particular environment. The building block of such an infrastructure is comprised of hundreds or thousands of small, low cost, multifunctional devices which have the ability to sense compute and communicate using short range transceivers known as sensor nodes. The interconnection of these nodes forming a network called wireless sensor network (WSN). The low cost, ease of deployment, ad hoc and multifunctional nature has exposed WSNs an attractive choice for numerous applications. The application domain of WSNs varies from environmental monitoring, to health care applications, to military operation, to transportation, to security applications, to weather forecasting, to real time tracking, to fire detection and so on. By considering its application areas WSN can be argue as a traditional wired or wireless network. But in reality, these networks are comprised of battery operated tiny nodes with limitations in their computation capabilities, memory, bandwidth, and hardware resulting in resource constrained WSN. The resource constrained nature of WSN impels various challenges in its design and operations degrading its performance. On the other hand, varying numbers of applications having different constraints in their nature makes it further challenging for such resources constrained networks to attain application expectations. These challenges can be seen at different layer of WSNs starting from physical layer up to application layer. At routing layer, routing protocols are mainly concerned with WSN operation. The presence of these challenges affects the performance of routing protocols resulting in overall WSN performance degradation. The aim of this study is to identify the performance challenges of WSN and analyze their impact on the performance of routing protocols. For this purpose a thorough literature study is performed to identify the issues affecting the routing protocols performance. Then to validate the impact of identified challenges from literature, an empirical study has been conducted by simulating different routing protocols, taking into consideration these challenges and results are shown. On the basis of achieved results from empirical study and literature review recommendations are made for better selection of protocol regarding to application nature in the presence of considered challenges.

Abstract:
In this study, a dynamic resource management and subscriber profile prediction scheme for mobile communication systems is presented. The aim is to achieve a high level of QoS for both handoff calls and new calls, while at the same time to improve the utilization of wireless network resources. The simultaneous satisfaction of these two actually conflicting interests will be thanks to two major key features. First, it will be due to the individual subscriber profile based prior information about handoff reservation requests that are provided by the mobile terminals. This information is based on the cell transition probabilities calculated by the mobile itself using collected information during past operations. Second, it will be due to a two-way approach implemented in the resource management processes. The two-way approach controls both the amount of reserved radio channels and the new call admission in a dynamic way, depending on the subscriber mobility and network traffic conditions.

Most of transportation networks interacts with other to support our modern society way of life. The proper performance of interdependent networks depends on the normal operation of the networks that are interconnected. The aim of this thesis is to measure and analyze the robustness of different interdependent networks models under large-scale failures and, in particular, to consider interdependent networks where at least one of the networks is a telecommunication network. Both, the effects of different network models and the dynamic process of failure propagation between networks are considered. New interconnection strategies are proposed to improve the robustness of the interconnected networks by analyzing the vulnerability of networks to failures and targeted attacks. Moreover, an enhanced region-based interconnection model is proposed by considering a limit to the number of interlinks between the interconnected nodes.

This paper presents a new partitioning strategy with the objective of increasing scalability by reducing computational effort of routing in networks. The original network is partitioned into blocks (subnetworks) so that there is a bi-directional link between any two blocks. When there is a connection request between a pair of nodes, if the nodes are in the same block, we only use the small single block to derive routings. Otherwise we combine the two blocks where the two nodes locate and in this way the whole network will never be used. The strategy is generic in that it can be used in any underlying routing algorithms in the network layer and can be applied to any networks with fixed topology such as fixed wired subnetworks of the Internet. The performance of this strategy has been investigated by building a simulator in Java and a comparison with existing stochastic partitioning techniques is shown to give superior performance in terms of trade-off in blocking probability (the probability of failure to find a path between source and destination satisfying QoS constraints) and reduction of computational effort.

Abstract:
The telecommunications industry was one of the first to adopt data mining technology. This is most likely because telecommunication companies routinely generate and store enormous amounts of high-quality data, have a very large customer base, and operate in a rapidly changing and highly competitive environment. Telecommunication companies utilize data mining to improve their marketing efforts, identify fraud, and better manage their telecommunication networks. However, these companies also face a number of data mining challenges due to the enormous size of their data sets, the sequential and temporal aspects of their data, and the need to predict very rare events—such as customer fraud and network failures—in real-time. The popularity of data mining in the telecommunications industry can be viewed as an extension of the use of expert systems in the telecommunications industry (Liebowitz, 1988). These systems were developed to address the complexity associated with maintaining a huge network infrastructure and the need to maximize network reliability while minimizing labor costs. The problem with these expert systems is that they are expensive to develop because it is both difficult and timeconsuming to elicit the requisite domain knowledge from experts. Data mining can be viewed as a means of automatically generating some of this knowledge directly from the data.

Abstract:
We analyze the impact of the structure of the Data Gathering (DG) trees on node lifetime (round of first node failure) and network lifetime (minimum number of rounds by which the network gets either disconnected due to node failures or the fraction of coverage loss reaches a threshold) in wireless sensor networks through extensive simulations. The two categories of DG trees studied are: the Bottleneck Node Weight-Based (BNW-DG) trees and Bottleneck Link Weight-Based (BLW-DG) trees. The BNW-DG trees incur a smaller diameter and a significantly larger fraction of nodes as leaf nodes: thus, protecting a majority of the nodes in the network from simultaneously being exhausted of the energy resources (contributing to a significantly larger network lifetime); nevertheless the nodes that serve as intermediate nodes in the first few instances of the BNW-DG trees are bound to lose their energy more quickly than the other nodes, leading to a smaller node lifetime compared to that of the BLW-DG trees (that incur a larger diameter and a relatively lower fraction of nodes as leaf nodes).
