虚拟容错路由协议分析和改进研究

Analysis and Improvement of Virtual Fault-tolerant Routing Protocol

对现在的虚拟容错路由协议进行了分析,主要是介绍了VRRP和HSRP协议,对VRRP和HSRP分别进行原理介绍和应用分析,在此基础之上发现了这些协议冗余路由在实现容错时存在这物理设备的浪费,提出的改进主要是在VRRP和HSRP的基础上进一步的对这些路由设备充分利用,提出了利用现有线路和技术实现了静态和动态的负载均衡,并与这些标准兼容。这些改进能很好的为现有网络所利用,改善了网络环境。

The existing virtual fault-tolerant routing protocols,particularly the VRRP and HSRP protocols are described,their principles and applications are analyzed.Based on this,it is found that these protocols could not make full use of the physical routers in the realization of the redundant fault-tolerance.By taking advantage of these routing equipment,and making use of the exiting lines and technology the static and dynamic load-sharing of traffic is achieved,and is compatible with these standards.These improvements could realize the full use of existing networks,better the network environment,without any replacement of the existing agreement.
