目的：是寻找网络阻塞问题的一种解决方案，使用连接建立有限的波长资源最大化，提高网络的阻塞性能是关注的焦点。根据业务的特点应当选择阻塞率性能参数作为动态RWA问题的优化目标，选择阻塞率最小的方案，同时也意味着在有限的网络资源下能够支持建立数量尽可能多的光通道连接。利用动态算法进行了分层图模型的动态仿真，同时解决动态算法中的波长分配和选路。结果表明，动态RWA算法具有降低网络阻塞的幅度、网络稳定性优良、资源利用率较高的特点。建立的光连接数增多，阻塞率明显变小。

It is to find a solution to network congestion problems,using the connection to establish the wavelength of the limited resources to maximize,improving the network blocking performance is the focus of attention. According to the characteristics of the business, choose blocking performance parameters as dynamic RWA goal of problem of the optimization,selecting the plan of minimal blocking rate. At the same time,it also means in the limited network resources to be able to support a number of optical channel connection as much as possible. Apply dynamic algorithm for dynamic simulation of the layered graph model,simultaneously solving the wavelength al-location and routing in dynamic algorithm. Results show that the dynamic RWA algorithm can reduce the size of the network congestion, with good stability and high resource utilization rate. The light of the connection built increases and blocking rate decreases significantly.
