Examining of Blocking Probability Computation in Optical Network

In this work, we examine analytical techniques; blocking probability is the statistical Probability that a connection cannot be established due to insufficient transmission. Resources in the network, usually expressed as a percentage or decimal equivalent of calls blocked by the network congestion during the busy hour. We also have shown an analytical model for evaluating the blocking probability in optical burst switched networks. This analytical model takes into consideration the effects of the burst offset time and the burst length of blocking probability.
