摘要
网闸是连接不同安全等级网络之间的桥梁,双机热备技术为解决网闸设备单点故障(SPOFs)提供了可靠保障。根据VRRP 1.0开源协议,对链路全对称网闸双机热备协议进行改进,开发了一种链路非对称网闸双机热备应用协议。解决了目前基于网闸的高可用方案链路交叉切换容易锁死的问题,提高了链路的收敛速度和切换性能。所提方案对研究和设计网闸高可用方案具有重要实用价值和指导意义。
Netgap acts as the bridge to connect the networks with different security levels,and the hot standby technology provides a reliable guarantee to solve the single point of failures(SPOFs)of netgap.According to virtual router redundancy protocol(VRRP)1.0,the hot standby protocol of link symmetric netgap is improved,and a hot standby application protocol of link asymmetric netgap is developed,which can solve the problem that the link cross switchover of high availability scheme based on netgap is easily locked,and improve the convergence speed and switchover performance of the link.The proposed scheme has great practical value and guiding significance for the research and design of netgap high availability scheme.
