Abstract :
Analytical and simulation techniques are presented to investigate the impact of multiple link failures on the availability performance of class sharing, pool sharing, and dedicated mesh restoration schemes. Formulations are given to synthesize distributed point-to-point traffic that is used in the analysis and simulation studies. It is shown that the availability of backup resources is a function of the number of "troublesome" links along the working paths of demands that share these resources. It is also shown that demands can receive a carrier grade service only when they are routed over very short distances with working paths not exceeding 2 hops.
