Embodiment 1
[0062] figure 2 It is a flowchart of a method for improving service reliability in a virtual private network according to the first embodiment of the present invention, such as figure 2 As shown, two BNGs (primary BNG and standby BNG) use Bidirectional Forwarding Detection (BFD) protocol for link state detection, and use Virtual Router Redundancy Protocol (VRRP, Virtual Router Redundancy Protocol) protocol for B NG The active and standby status is negotiated, and user information is backed up between the active device and the standby device. BNG1 is the active device and BNG2 is the standby device. In this example, the backup BNG advertises routing information to the main BNG before the downlink of the main BNG fails. The method for improving service reliability in a virtual private network in this example specifically includes the following steps:
[0063] Step 201: Establish a TCP connection between BNG1 and BNG2 as a message channel for backing up online user information (in...
Embodiment 2
[0072] image 3 It is a flowchart of a method for improving service reliability in a virtual private network according to the second embodiment of the present invention, such as image 3 As shown, two BNGs use the BFD protocol for link state detection, use the Virtual Router Redundancy Protocol (VRRP, Virtual Router Redundancy Protocol) protocol for B NG active and standby state negotiation, and perform user information between the active device and the standby device For backup, BNG1 is the main device and BNG2 is the backup device. The difference between this example and the above example is that the standby BNG advertises routing information to the active BNG after the downlink of the active BNG fails. The method for improving service reliability in a virtual private network in this example specifically includes the following steps:
[0073] Step 301: Establish a TCP connection between BNG1 and BNG2 as a message channel for backing up online user information (including VPN u...
