In this article, the subject of study is a network multiservice infrastructure based on the architectural concept future networks FN (Future Network) with using the technology software- defined network — SDN (Software Defined Networks), which supports a wide range of services. The basis of this architecture is multiservice telecommunications networks with using SDN technology, consisting a set of specialized modules, responsible for various functions for organizing network interaction. SDN is a dynamic, manageable and adaptable network architecture, which is divided into network management and data transmission levels, which provides software network management.
The purpose of this work is to research and analyze MTN performance indicators based on the architectural concept FN with using SDN technologies in the provision multimedia service. As the SDN network performance, the probability -time characteristics of the useful and service traffic, the risks to the threat information security, and the resiliency indicators of the functioning of the systems where chosen. The complex performance indicators multiservice telecommunications network based on FN network with using SDN technologies are investigated.
As a result MTN research using the architectural concepts FN networks, a mathematical model network performance is proposed. Analytical expressions are obtained, allowing to evaluate indicators quality of service, information security and fault tolerance of the functioning of the system when providing multimedia services.

Keywords: future networks, SDN, reliability, performance, fault tolerance, firewalls, quality of service, security risk, DDoS attack.
