dynamically survivable wdm network design with shared-cycles-based pwce
The concept of a protected working capacity envelope (PWCE) is very attractive for designing a dynamically survivable WDM network. In this paper, we consider a shared-cycles-based PWCE approach for designing survivable WDM networks where the traffic demand is dynamically changing. We develop an integer linear programming formulation to determine the protected working capacity envelope and use simulations to evaluate the blocking performance.
