摘要
针对现有容错系统中主备机切换过程时延较大的问题,设计了一种主备机快速切换的容错系统。在该系统中,主备机使用相同IP地址和MAC地址,它们同时接收网络数据,但备机不发送任何网络数据,且该过程对上层应用透明。
To shorten the time-delay of active/standby switching in the fault tolerance system, an active/standby fast-switching system was designed. In this system, the active and the standby used the same IP and MAC address in order to receive the network data simultaneously, however, the standby was prohibited to send any network data, both processes were transparent to upper layers.
