摘要

为了提高IP RAN（IP无线接入网）的可靠性

降低网络发生故障时造成的损失

对现有的LSP（标签交换路径）保护、PW（伪线）冗余保护、VPN（虚拟专用网）FRR（快速重路由）和VRRP（虚拟路由冗余协议）进行了研究。调查了目前工程上常用的网络部署结构

总结出一个通用的包含接入层、核心汇聚层的网络结构模型。通过分析各种情况下发生故障的情况

设计一种方案将多种技术融合应用

使网络在多种故障情况下依旧能够正常运行

提高了网络的可靠性

可为各工程部署网络时提供一定的参考。

Abstract

In order to improve the reliability of IP Radio Access Networks（IP RAN）and reduce the losses caused when they break down

the existing network protection technologies

such as LSP protection

PW redundancy protection

VPN FRR

VRRP are studied.The network deployment structures commonly used in present projects are investigated and a general model containing access layer

convergent layer and core layer summarized.On the basis of analyzing faults occur in various situations

a scheme that integrates multiple technologies is designed so as to ensure the normal operation of the networks

improving network reliability and providing certain reference for network deployment.
