Abstract :
Two multi-layer network backup capacity recovery mechanisms, which are static and dynamic mechanisms, have been proposed to realize survivability strategy in IP over WDM multi-layer network. Compared with the static one, the dynamic backup capacity mechanism is adopted as its flexibility which is more suitable for the development in the current network. To achieve better performance of resource utilization, a novel method is studied in this paper, which combines mechanism with the pre-allocated restoration as the survivability strategy technique. This method is able to adjust the link weight value according to current state of network. Simulation result proves that load on the network is efficiently balanced and resource utilization is improved by this method.
