Abstract
The analysis of the advantages using the architectural concept future networks FN (Future Networks), to build high-performance multiservice telecommunication networks (MTN), supporting a wide range multimedia services. A mathematical model MTS performance is proposed based on the architectural concept future FN networks using virtual, channel, information and network resources. The network performance model differs from the well-known ones in that in order to ensure an acceptable quality of service QoS (Quality of Service) and QoE (Quality of Experience) perception in the common existing NGN architecture public multi-service networks, a new innovative technology and four target settings future networks were used FN. According to ITU-T, Y.3001 and ITU-R, M. 2083-3 Recommendations, SDN (Software Defined Networking), NFV (Network Functions Virtualization), LTE (Long Term Evolution) and IMS (Internet Protocol Multimedia Subsystem)are proposed as the basis innovative technologies for building a multi-service network infrastructure (Internet Protocol Multimedia Subsystem), which will enable the organization optimal management and allocation throughput resources, and efficient network operation. Based on the proposed mathematical model, the complex MTS indices were studied, such as network throughput, efficient use virtualization network and information resources, probability-time characteristics of networks, structural reliability and information security, and economic efficiency and cost system hardware-software and terminal tools for multimedia rendering services. Analytical expressions are obtained for evaluating the integrated performance indicators MTN based on FN in the provision multimedia services. On the basis of the model, a numerical analysis was carried out and a graphical dependence of the maximum network bandwidth on the total number hardware and software systems and terminal means at a given system load factor was constructed. It was found that an increase in the total number hardware and software systems leads to an increase in the maximum throughput that meets the requirements QoS & QoE for various services based on ETSI. Based on the analysis, actual problems are identified recommendations are developed to increase the efficiency using IntServ and DiffServ architectures for MTN.
Keywords:future networks, SDN, reliability, performance, fault tolerance, IMS, quality of service, security risk, NFV, efficiency, limited resources.
