首发时间:2012-12-06
摘要:随着DWDM在核心节点的使用,网络的灵活性,可靠性都有了很好的保障,带宽容量也已经有了很大程度的提升。但是,这些年移动互联网飞速发展,各种新型业务层出不穷,对于带宽带宽和大容量业务的传输需求不断增加,给现有的网络带来了前所未有的压力。光流交换网络可以更好的适应这些业务。如何能够发挥光流交换网络高速处理的特点,从而高效的利用频谱资源,渐渐的引起人们的关注。这篇文章介绍了一种基于光流交换网络的流量疏导算法(Optical Grooming with Priority,OG-P),在一定程度上可以更加充分的利用现有资源,减少网络的阻塞率。仿真实验的结果证明这种算法可以实现上述目的,提升了网络性能。

An Algorithm of Optical Gromming in Optical Flow Switching Network
Abstract:With the application of DWDM in core nodes, bandwidth capacity has increased in a large degree, while the flexibility and the reliability of networks have been guaranteed well. But, in recent years, the challenges, such as rapid development of mobile Internet, emergence of all kinds of new business and increasing demand for bandwidth and large capacity business transmission, have brought the unprecedented pressure to the existing network. How to make full use of high speed processing in optical flow switching network, in order to increase the spectrum resources utilization rate, and implement traffic grooming, begins to draw more and more people's attention. This paper introduces a kind of algorithm based on Optical Grooming with Priority, in order to fully utilize the existing resources and reduce network blocking rates.
Keywords: communication system flexible grid optical switching network optical grooming
