Abstract

In recent days, optical fibers have been developed as a transmission medium to carry traffic in order to provide various services in telecommunications platform. Failure of this fibre caused loss of data which can interrupt communication services. Thus, this paper will focus about protection scheme in order to guarantee the survivability of the networks. Besides, the scheme should provide better quality of services (QOS) in terms of network resource usage, connection availability satisfaction ratio (ASR) and blocking probability. A sample of mesh torus network was carried out to compare several basic connection management processes and dedicated protection scheme was taken into consideration. Matlab was used as a simulation platform in this project. Analyze for performance metrics will shown that there are significant improvements of availability satisfaction Ratio (ASR) when dedicated path protection is utilized in optical network. This project provides an insight of advanced in protection scheme and can serve as a foundation for future research.

光网络生存性专用保护方案

近年来，为了在电信平台上提供各种业务，光纤被发展成为承载业务的传输介质。这种光纤的故障会导致数据丢失，从而中断通信服务。因此，本文将重点研究保护方案，以保证网络的生存能力。此外，该方案应在网络资源利用率、连接可用性满意度(ASR)和阻塞概率方面提供更好的服务质量(QOS)。以网格环面网络为例，比较了几种基本的连接管理过程，并考虑了专用保护方案。本课题采用Matlab作为仿真平台。对性能指标的分析表明，在光网络中采用专用路径保护后，可用性满意度(ASR)得到了显著提高。本项目提供了对保护方案先进程度的了解，可为今后的研究奠定基础。
