Study on Soft-switching Dual-homing and Disaster-tolerant Networking Technology
2010
The off-site disaster recovery of soft-switching equipment is an important measure for improving network security and providing reliable services,It ensures that the system continue to provide services when the failure occurs in certain soft-switching node.Dual homing(Dual Homing) is a network topology,with device connected to the network at independent access points.With an access point as the principal connection,the back connection would be activated when the principal connection fails.This paper examines some key disaster recovery techniques in dual homing l+l mutually supportive manner.Fault detection;data synchronization switching gives the corresponding solutions for failure detection,data synchronization switching are also given in this paper.
