Derivatives of Blocking Probabilities for Multi-service Loss Systems and Their Applications

摘要: Derivatives of blocking probabilities multi-service loss networks are important for traffic engineering. An explicit formula the derivatives with respect to offered traffics is obtained expressed by stationary global state probabilities. The approach based on convolution algorithm. It allows us find expressions in a much more easy way than known so far. briefly shown how can be applied approximate evaluation performance measures and studying error estimation caused small changes traffic. results also network optimization.
