Problems solved by technology

[0011] In this way, when a large number of BGP packets are directly sent to the active device for processing, the active device needs to allocate a large cache space to cache these BGP packets, which takes up a large cache space and a large amount of CPU resources to process these BGP packets

Embodiment Construction

[0029] In the prior art, after receiving the BGP message sent by the BGP peer, the standby device directly sends it to the active device for processing. In this way, the active device needs to occupy a large amount of CPU resources to process these BGP messages. In order to solve the above-mentioned problems in the prior art, the following embodiments of the present application provide a stacking system BGP packet processing method and a device to which the method can be applied.

[0030] In the method of the embodiment of the present application, the backup device enables the TCP proxy function, and after receiving the BGP message sent by the BGP peer, buffers the received BGP message, and sends a notification message to the active device. After the notification message is processed by the device, the cached BGP message is deleted.

[0031] Specifically, such as figure 1 As shown, the BGP message processing method of the stacking system in the embodiment of the present appli...

Abstract

The present invention discloses a BGP (Border Gateway Protocol) message processing method and device of a stack system. The stack system operates a BGP protocol and comprises a master and a slave. The method comprises: a TCP (Transmission Control Protocol) agency function is available when the slave is used; buffering the received BGP message and sending a notification message to the master after receiving BGP message emitted by a BGP peer pair; and deleting buffered BGP message after the master processes the notification message. The buffer space of a master is saved, and the CPU resource occupy of a master is reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a BGP message processing method and device of a stacking system. Background technique [0002] BGP (Border Gateway Protocol, Border Gateway Protocol) is a dynamic routing protocol that can be used not only between different ASs (Autonomous Systems, autonomous systems) but also within the same AS. A router running the BGP protocol is called a BGP speaker. Two BGP speakers can establish a BGP neighbor relationship, and establish a TCP (Transmission Control Protocol, Transmission Control Protocol) connection during the establishment of the BGP neighbor relationship. After the TCP connection is established, they can exchange routing information with each other. At this time, this Two BGP speakers are BGP peers. [0003] The packet types in the BGP protocol mainly include the following types: [0004] Open: The first message sent after the TCP connection...
