To develop a various routing theme for coping with multiple, presumably related to failures. Isolated single link failures is effectively restrained disjoint path protection, however mechanisms for sick from multiple failures isn't warranted. especially, events like natural disasters or intentional attacks will result in multiple related to failures, that recovery mechanisms don't seem to be well understood. so as to agitate these problems, a probabilistic read of network failures are created wherever multiple failure events will occur at the same time, and supported this, sure algorithms are developed that is employed for locating various routes with minimum joint failure chance. Therefore, a Probabilistic Shared Risk Link cluster (PSRLG) framework is developed for modeling related to failures. during this context, the matter of finding two methods with minimum joint failure chance is developed as associate number Non-Linear Program (INLP), and additionally the approximations and linear relaxations which will realize nearly best solutions in most cases are developed.
