Abstract

Survivability is an important issue in communication networks. Protection and restoration are two mechanisms to provide the survivability. Conventional restoration scheme is classified into link and path restoration. This paper proposed a new hybrid restoration scheme that combines link and path restoration methods using priority wavelength strategy. This new method provides better recovery blocking probability than the conventional link/path restoration method. Due to the characteristics of protection methods, which must reserve spare capacity and is stiff to variable traffic, we further proposed a dynamically adjusted protection scheme that can have more flexible usage of network resource and gives better recovery blocking probability. We simulate the performance and compare with the conventional protection/restoration schemes. The results show that the proposed methods have better recovery blocking probability than others.
