摘要: 本文提出了一种应用于IP/MPLS-OTN-DWDM三层网络的网络保护模型。在该架构之中，明确的将OTN层看成单独的层，同时考虑其本身的技术约束。在网络生存性设计上，在减少保护资源的前提下规定每层只保护常规容量以实现最大化保护效果。同时提出了一种启发式解决方案，将该问题分成三个子问题，降低复杂度，最后通过一个基于多网络参数的仿真实验，以探明其对保护容量和整体开销的影响。
Abstract: We propose a protection architecture of three-layer network with IP/MPLS-OTN-DWDM. In this architecture we regard OTN layer as a single layer considering its own technology constraints. In the design of network survivability, the architecture will only protect its normal capacity to reduce protection resource while maximizing the effect of protection. What's more, a heuristic approach is proposed to lower the complexity by dividing the problem into three sub problems. Then we present a study based on multi-parameter of network in order to understand their influence on protection capacity as well as the overall network cost.
