WDM光网络中动态RWA算法仿真的实现

在WDM光网络中，在给定一组连接请求后，需要为之建立路由并分配波长，这被称为路由和波长分配问题（RWA）。由于当前光网络中的业务呈现爆炸式的增长，而光网络中的可用资源却是有限的，因此如何使用合理的RWA算法来优化网络资源的利用就显得尤为重要。目前已有很多文献提出了基于各种优化目标的RWA算法，也都通计算机仿真的方法测试和评估了算法的性能。计算机仿真是进行算法性能评估的主要手段，但是关于算法仿真的实现，—般的文献都涉及的很少，本文主要研究了WDM光网络中动态RWA算法计算机枋真的实现。

The Realization of Dynamic RWA in WDM Optical Network

In WDM optical network it is required to set up links and assign wavelengths after linking request arrived, which is called routing and wavelength assignment(RWA). Today it is more important to make the best use of the network resource because of the explosive traffic increase on optical network. Many RWA algorithms based on special goal were presented in papers so far, and the performance of these algorithms was evaluated by computer simulation. Computer simulation is important way to evaluate the performance of algorithm, but few papers give the realization of these simulations. So the realization of dynamic RWA algorithm based on computer simulation is studied in this paper.
