带波长转换的波长路由光网络的性能评估
Performance Evaluation of Wavelength Routed Optical Network with Wavelength Conversion
摘要：
电信网络的快速发展是由用户对新应用和技术进步的需求驱动的。互联网业务的爆炸式增长是由于其用于收集信息、通信、多媒体应用、娱乐等，这些应用对电信网络的带宽容量提出了巨大的需求。光纤的引入已证明满足了对带宽的巨大需求。全光网络能够以50 Tbps的速率传输海量数据，可以满足这些要求。本文提出了一种波长转换技术，以降低波长路由网络中的阻塞率。可以看出，业务请求的阻塞概率随着波长转换因子的增加而减小。我们爆炸的可能性，不同的网络规模与变化的波长每链路。在这项工作中的波长路由光网络的评估与不同数量的波长转换器，不同的业务类型进行，结果表明，阻塞概率是最小的50%至60%的波长转换节点。波长可转换节点数超过60%时，对降低阻塞率没有太大作用，反而增加了网络的总开销。
英文摘要：
The rapid development of telecommunication networks is driven by user demands for new applications and advances in technologies. The explosive growth of the internet traffic is due to its use for collecting the information, communication, multimedia application, entertainment, etc. These applications are imposing a tremendous demand for bandwidth capacity on telecommunication network. The introduction of fiber optics had proved to meet the huge demand of bandwidth. These requirement can be meet by all optical network which is capable of transmitting enormous data at very high speed, around 50 Tera bits per seconds (Tbps) A wavelength conversion technique is addressed in this paper to reduced the blocking probability in wavelength routed networks. It is seen that the blocking probability of traffic requests decreases as the wavelength conversion factor increases. We explode the possibility for network with different size with variation in wavelength per link. In this work the evaluation of wavelength routed optical network with varying number of wavelength converters, different traffic types are carried out and results are shown that the blocking probability is minimum with 50% to 60% wavelength convertible nodes. Wavelength convertible nodes more than 60% are not showing much effect on reduction in blocking probability rather it results in increase in overall cost of network.
