Problems solved by technology

[0005] In the process of adopting the scheme of retransmitting all routes after the above-mentioned switching, the inventor found at least the following problems in the prior art: the scheme cannot resume transmission from breakpoints. In the master-standby switchover, the packets in the send buffer have not been sent to some peers, so after the switchover, for this part of the peers, the standby boards do not continue to send from their respective positions before the switchover, but start together with the sent routes. Repackage it into a packet and send it. In this way, not only will there be broken packets, but it will consume a lot of system and network resources after the switchover, and the standby board will respond slowly to topology changes.

Embodiment 1

[0039] This embodiment provides a processing method for active / standby switchover, which is suitable for being deployed on a mainboard of a router. Such as figure 1 As shown, the method includes:

[0040] Step 101, before sending the corresponding packing group to the peer under the session at any end, backing up the corresponding at least one packing group to the standby board;

[0041] Step 102, recording the backed-up packing group, and generating a main board sending rule linked list according to the order of backup, so that the backup board generates the same spare board sending rule linked list as the main board sending rule linked list according to the backup order;

[0042] Because in the process of backing up the packing group, the motherboard is copied one packing group by one packing group, so the order of the above backup is the order of copying the packing groups.

[0043] Step 103: Send the packet group according to the order of the main board sending rule link...

Embodiment 2

[0047] This embodiment provides a processing method for active / standby switchover, which is suitable for being deployed on a mainboard of a router. Such as figure 2 As shown, the method includes:

[0048] Step 201, receiving at least one packing group backed up by the motherboard before sending the corresponding packing group to neighbors under any session;

[0049] Step 202, recording the backed up packaged group, and generating the same spare board sending rule linked list as the main board sending rule linked list according to the sequence from the backup;

[0050] Step 203, listening to the sending progress of the mainboard's sending rule linked list according to the order of the standby board's sending rule linked list;

[0051] Step 204 , after the active-standby switchover, continue the detected progress and send the corresponding backup packaged group to realize breakpoint resume transmission.

[0052] The processing method convenient for active-standby switchover ...

Embodiment 3

[0054] This embodiment specifically describes a processing method that facilitates active / standby switchover. This method mainly involves the main board and the standby board. For description, wherein, in this embodiment, the message is specifically an update (update) message in BGP. Such as image 3 As shown, the method includes:

[0055] Step 301, before the main board sends the message in the corresponding packing group to the peer under peer session A, back up the corresponding at least one packing group to the backup board, wherein, in each packing group backed up by the main board, at least Including the message and the following information: each packing group ID and the main board stores the sending buffer ID of each packing group, and this information is used for the standby board to generate and communicate with each backup packing group after receiving each backup packing group The sending rule linked list of the main board is the same as the sending rule linked l...

Abstract

The embodiment of the invention discloses a processing method, device and system convenient for main / backup switching, which relates to the technical field of communication and solves the technical problems that the prior art can not realize HTTP after main / backup switching, resulting in the waste of network resources. The method of the embodiment of the invention mainly comprises the steps of: before transmitting corresponding packaging groups to neighbors under sessions of any end, backing up the corresponding at least one packaging group to a backup board; recording the packaging group backed up and generating a main board transmitting rule linked list according to the backup order, so that the backup board generates a backup board transmitting rule linked list which is same as the main board transmitting rule linked list according to the backup order; and transmitting the packaging group according to the order of the main board transmitting rule linked list, so that the backup board monitors the transmission progress of the main board according to the backup board transmitting rule linked list, thereby carrying out HTTP after main / backup switching. The embodiment of the invention is mainly applied to networks.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method, device and system for facilitating active / standby switching. Background technique [0002] With the continuous development of IP technology, operators have higher requirements on the reliability of IP network, and non-stop routing (Non-Stop Route, NSR) technology emerges as a high-reliability solution. The NSR technology is a technology that the neighbor (peer) control plane is not aware of when the control plane of the main board of the router fails and there is a backup control plane of the backup board. The main realization is that the routing capability will not be interrupted when the router with active / standby redundancy configuration is switched and restarted. That is, multiple adjacent routers are supported to be switched at the same time, and the forwarding of routes is not interrupted. [0003] Group-based packaging in Border Gatewa...
