【摘要】 为了保证网络服务的稳定性,提高网络冗余链路的切换速度,文中分析了Windows驱动程序接口规范中的失效恢复机制以及网络冗余链路切换过程中数据包丢失的原因。通过采用主动发送ARP广播和重发数据的方法提高网络链路冗余切换速度,获得了快速切换的效果。在实际应用中,使用这种方法能够将网络冗余链路的切换时间降低到4ms。更多还原

【Abstract】 To ensure the stability of network service and improve the switch speed of different backup paths,the fail recovery mechanism of windows network driver interface specification and the reasons for loosing of the data packet during the process of switching different backup paths are analyzed.The switch speed of the different backup paths is improved by initiative sending ARP packet and retransmitting data packet.Experiments shows that the time of switching different backup paths is reduced to 4ms.更多还原
