• Evaluates the blocking of Dynamic WDM networks with heterogeneous traffic loads.
• The approach considers full wavelength conversion and fixed routing.
• It compares the impact on blocking probability produced by the load heterogeneity.
• The numerical examples show the potential great impact of the load heterogeneity over the network blocking probability.
This paper presents an efficient and accurate mathematical method to evaluate the blocking probability of burst loss in dynamic WDM networks with wavelength conversion. The proposed model allows different traffic loads to each network connection (heterogeneous traffic). It is shown that the traffic load heterogeneity on a network significantly affects the blocking probability of the connections, and for this reason, it should be considered in the network design and operation. The mathematical solution is efficient, allowing us to obtain the blocking probability of all users (connections) in less than a second for mesh network topologies. Another desirable characteristic of the proposed method is that it gets results very close to those obtained by simulation, but orders of magnitude faster.
