受保护的工作容量范围 (PWCE) 的概念对于设计动态可生存的 WDM 网络非常有吸引力。我们考虑采用基于 p 周期的 PWCE 方法来设计流量需求动态变化的可生存 WDM 网络。我们开发了一个整数线性规划公式来确定受保护的工作容量范围,并使用模拟来评估不同网络模型的阻塞性能。
The concept of a protected working capacity envelope (PWCE) is very attractive for designing a dynamically survivable WDM network. We consider a p-cycle-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 for different network models.
