Abstract

The existing QoS research is concentrated on mathematical models using MOS/R-factor estimation. The Research Department Technopark of the Central Science Research Telecommunication Institute (ZNIIS) has applied the service degradation model on a private model network and tested it under various payloads using different network technologies. The obtained results have shown irregular distribution of MOS/R for different services (service profiles – service modifications), which radically contradicts to the requirements of various traffic network performance (NP) defined by the international standards (ITU-T). The present paper describes the limited values of network performance and network productivity estimation approach for services with required QoS. Besides, the statistics of QoS behavior (MOS/R for etalon service) at various payloads and segment of network (access and transport stratum) are given. In conclusion, the typical recommendations for network operators are given including parameters for network configuration at different segments.
