<title>Analytical study of WDM-based all-optical networks with light-path reservation</title>

Abstract

In this paper, we present an analytical model to analyze and to evaluate the blocking performance of a WDM-based All- Optical Network when light-path reservation is introduced. The computed results show that the link blocking probability is marginally less with light-path reservation than when there is no reservation provided that the traffic is low and that no routing is allowed; while the path blocking probability reduces significantly at high traffic when light-path reservation is introduced. Furthermore, the mean blocking probability of the network is reduced for low traffic with light-path reservation and routing is allowed. However, for high traffic, light-path reservation increases the blocking probability. We also discovered that, for given traffic load, there exists an optimum reservation level at which one can achieve the minimum mean blocking probability.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
