Abstract :
In this paper we deal with reconfiguration of virtual topology. Routing of traffic through virtual and physical topology is investigated. Practical model for minimizing the difference between initial and reconfigured virtual topology is presented. The results show the utilization of the links and augmentation of the number of the lightpaths for two types of networks with different line system and different optical channel capacities.
