Embodiment Construction

[0135] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0136] Knowledge of the existing BGP protocol:

[0137] (1) The BGP protocol is a dynamic routing protocol between different autonomous systems. It achieves reachability between autonomous systems (Autonomous Systems, AS) by maintaining IP routing tables or IP address "prefix" tables. , network policy or rule set to determine routing.

[0138] Autonomous system AS is a collection of routing devices managed by the same management organization and using...

Abstract

The invention discloses a method and a device for processing a transmission control protocol TCP session. The method comprises the following steps: establishing a first TCP session and a second TCP session with neighbor routing equipment, and determining corresponding main and standby session capabilities; receiving an update message sent by neighbor routing equipment through a first TCP session of the main session capability, and marking an address family corresponding to a to-be-updated address prefix as a fault address family after determining that the update message comprises error information; switching main and standby session capabilities of the first TCP session and the second TCP session; sending a first capability message carrying the removal information of the fault address family and the main session capability identifier to neighbor routing equipment through a second TCP session; after the first capability response message is received through the second TCP session, sending the first notification message to the neighbor routing device through the first TCP session, disconnecting the first TCP session, and the stability of communication between the routing devices is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for processing a Transmission Control Protocol (TCP) session. Background technique [0002] Border Gateway Protocol (Border Gateway Protocol, BGP) is an external gateway protocol used to implement learning and calculation of routing information between different autonomous domains (or "autonomous systems"). To exchange routing information between routing devices through BGP, it is necessary to establish a BGP neighbor first, and configure each other as neighboring routing devices. Configuring neighboring routing devices is generally achieved by specifying the Internet Protocol (Internet Protocol, IP) address of the other party. After that, The two sides of the interaction can use the IP address pair consisting of their own IP address and the other party's IP address to establish a Transmission Control Protocol (Transmission Control Protoco...
