SYSTEMATIZATION OF APPROACHES TO THE DEVELOPMENT OF QUALITY SYSTEMS INDICATORS AND NETWORK SERVICES RELIABILITY

Over a long period of development of the network communication general user (NCGU), various models have been developed, focused on the service of voice traffic. In the next generation NGN heterogeneous communication network, voice traffic service has become one of the applications. This application was subject to stringent timing requirements (latency and loss). Further development took place to develop new applications that impose even more severe service requirements. Such applications have had a significant impact on the requirements and timing of next generation communications networks. In this regard, it was proposed in various recommendations to distinguish networks that provide services with strict requirements for time parameters into a new class of networks and call them networks with low and ultra-low delays.
