Abstract
In this paper, we present a new method for the estimation of blocking
probabilities in bufferless optical burst or packet switched networks. In
such networks, deflection routing is used to reduce blocking probability.
However, it requires certain wastage due to trunk reservation that must be
used to avoid instability. We provide a wide range of simulation and
numerical results to validate our new approximation method and demonstrate
various effects on blocking probability and utilization, such as network
size, trunk size, the maximal number of allowable deflections, and
burst/packet length.
