Calculation in the NGN Networks of Indexes of Reliability of Tracts of Transmission of Packet Information
Аннотация
Abstract: The article describes the main elements that make up the transport network NGN. Shows the relevance of research of reliability of the NGN network, as well as the need of numerical calculation of complex indexes of reliability of tracts of transmission of packet information is given. On the developed imitating model of the NGN network indexes of reliability of tracts of transmission of packet information are calculated when using mechanisms of reservation, and also at their absence. Numerical calculation of the main indexes of reliability (failure rate λ, average time of restoration of communications of Тв, average time of a time between failures То, Кг the coefficient of availability, probability P(t) of no-failure operation in the range of t, coefficient of operational readiness Rг) the NGN network equipment (router, switch) for the main period of operation is given. By the received results conclusions are makes.
