Abstract

Many existing literatures investigated the survivable routing and wavelength assignment strategies on WDM networks from the perspective of source routing which implies that the size of the network will heavily limit the scalability and the tractability of the problem. In this paper, we will probe into the same problem by means of the distributed processing within each node in the network. The proposed flooding based approach just uses the simple broadcast operation to the output ports by looking up the tables and can be easily integrated into the regular routing protocols implemented in each node. The simulations are made to verify the performance of this framework with comparison to the centralized version of the solution.
面向WDM光网络动态业务需求的基于泛洪的可存活RWA机制
现有的许多文献都是从源路由的角度研究WDM网络的生存性路由和波长分配策略,这意味着网络的规模将严重限制问题的可扩展性和可追溯性。在本文中,我们将通过网络中每个节点的分布式处理来探讨相同的问题。所提出的基于泛洪的方法仅通过查找表向输出端口使用简单的广播操作,并且可以很容易地集成到每个节点实现的常规路由协议中。通过仿真验证了该框架的性能,并与集中式解决方案进行了比较。
