Abstract

The invention relates to the field of communication technology and discloses a method and a system achieving network redundancy and data flow seamless switching. The method includes the following steps of using a virtual router redundancy protocol (VTRP) to trigger switching of a first transmitting device to a second switching device according to the changes of links, and using an open shortest path first (OSPF) interior gateway protocol to update route information and to switch the flow direction of the data flow. Main and standby switching is achieved through the use of the VRRP, and when the main and standby states of a VRRP group switch, and the OSPF interior gateway protocol is used for updating the route information and switching the flow direction of the data flow, so that after a linkage mechanism of the VRRP and the OSPF interior gateway protocol is used for achieving the switch, the route information is timely updated, the problem that the data flow direction is wrong and therefore the use of a user is affected is avoided, and the data flow seamless switching is ensured.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method and system for realizing network redundancy and data flow seamless switching. Background technique

[0002] With the rapid development of the Internet, users require more diverse business experiences and faster and more stable network services. This puts forward higher requirements on the redundancy, reliability, and disaster recovery of the network. Users need to maintain communication with the network at all times, and even if a failure occurs, they need to recover quickly without perception.

[0003] The Virtual Router Redundancy Protocol (VRRP) virtualizes multiple routers into one router and announces a virtual IP address to the outside, so as to realize fast backup switching when a device fails. The router in the VRRP state is the Master, which is responsible for forwarding data packets, and other Backup devices are in the hot standby state. Many important...
