双线热备机制的研究

Research on Hot Standby Mechanism of Dual Line

随着网络应用的快速普及,网络的高可用性显得尤其重要。网络的短时间中断,就会导致极大的经济损失,甚至是不良的社会影响,因此,如何保障网络安全稳定运行已经成为网络发展的重要课题之一。对于网络的稳定性和高可用性有多种实现方法,双线路热备为网络通畅提供了极大的保障。本文对策略路由、聚合端口和STP这3种双线热备方式的机制进行了深入研究,并对其适用范围和优缺点进行了分析对比。

With the rapid popularization of network applications,the high availability of the network is particularly important.The short-term interruption of the network will lead to great economic losses and even adverse social effects.Therefore,how to ensure the safe and stable operation of the network has become one of the important topics of network development.There are many ways to achieve the stability and high availability of the network,and the dual line hot standby provides a great guarantee for the smooth net⁃work.This paper studies the specific implementation methods and effects of the three dual line hot standby modes,namely policy rout⁃ing,aggregation port and STP,and analyzes and compares their application scope and advantages and disadvantages.
