Abstract

The authors address the issue of telecommunications network protection, with particular reference to optical fibers and the new topologies made possible using the SONET signal format. It is found that the introduction of SONET-based networks provides an ideal opportunity to reappraise protection methodologies and to improve customer circuit availability significantly. The authors propose techniques for achieving these aims by examining a whole network from customer to customer so that weak links in the chain can be identified. In this manner, the network operator can be sure that investment in infrastructure is correctly targeted to provide a service that satisfies the customers' expectations.<>
基于SONET的网络保护
作者讨论了电信网络保护的问题,特别提到了光纤和使用SONET信号格式可能实现的新拓扑。研究发现,引入基于sonet的网络为重新评估保护方法和显著提高客户电路可用性提供了理想的机会。作者提出了通过检查从客户到客户的整个网络来实现这些目标的技术,以便识别链中的薄弱环节。通过这种方式,网络运营商可以确保对基础设施的投资是正确的,以提供满足客户期望的服务。
