A new provisioning framework to provide availability-guaranteed service in WDM mesh networks

In this paper, we present a connection-provisioning framework to satisfy customers´ availability requirements using appropriate protection schemes. The framework contains two pats: (a) WDM mesh network service availability analysis; and (b) a connection-provisioning approach using the analysis. We present the availability analysis for connections with different protection schemes (i.e., unprotected, dedicated, or shared protected) and propose an integer linear program (LIP) based provisioning approach for static traffic. We verify the theoretical availability analysis through simulations, and demonstrate the effectiveness s of our provisioning approach using numerical examples.
