P圈技术研究

P-ring Technology Study

由于通信在人们的生活中扮演着越来越重要的角色,人们对通信质量的要求也就越来越高,因此,网络保护技术研究备受关注。本文对环网和网状网的优劣势比较入手引入P圈,然后重点详细介绍具备环网恢复速度快和网状网资源利用率高的预配置保护环(简称P圈):对链路P圈、节点P圈及P圈的多种评价标准都做了详细分析。

Due to the communication plays an increasingly important role in people＇s lives,the requirements of the communication quality is more and more high network protection technology research concern.In this paper,the advantages and disadvantages of ring networks and mesh networks start with the introduction of the P-ring,and then focus on details have the ring network to restore the speed and mesh network resource utilization pre-configured protection ring （referred to as the P-ring）： the link P-ring,node P-ring and P ring a variety of evaluation criteria are analyzed in detail.
