Embodiment Construction

[0095] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0096] Generally, when adjusting the forwarding path of the message, there are the following two traditional control schemes, which will be explained respectively below.

[0097] Traditional Control Scheme 1

[0098] by figure 1 Take the network shown as an example. For the packets between destination node A and source node B, if the link between AS2 and AS1 is congested and the forwarding path of the packets needs to be adjusted, you can do the following: Modify BR1 and BR2 respectively In the routing message published to AS2, the AS PATH in the routing message includes 4 numbers of AS1; in the routing message published by BR3 and BR4 to AS4, ASPATH includes 1 number of AS1; in the routing message published by...

Abstract

An embodiment of the present invention provides a routing control method and a border router. The method includes: the first BR obtains a first routing control message, and the first routing control message includes the identity of the message forwarding endpoint and the first AS list, The first AS list is used to indicate a packet forwarding path, and the first AS list includes at least two AS identities in sequence; the first BR determines the first BR according to the first AS list Whether the AS to which it belongs is the first AS on the path, and the first AS includes the destination node of the path; if yes, the first BR advertises the first route to the second AS on the path A control message and a first BGP routing message, where the first routing control message further includes the identity of the first BR, and the first BGP routing message includes the identity of the first BR. It helps to achieve the purpose of packet forwarding according to the specified path.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a routing control method and a border router. Background technique [0002] Generally, an autonomous system (English: Autonomous System, referred to as: AS) includes the following three types of devices: provider edge (English: Provider Edge, referred to as: PE) equipment, border router (English: Border Router, referred to as: BR) and Provide (English: Provider, referred to as: P) equipment. Wherein, PE and BR may be collectively referred to as edge devices of the AS, PE is a user-side access device, and BR is an Internet service provider (English: Internet Service Provider, ISP for short) side access device. [0003] Generally, before packet forwarding, the BR of the first AS can establish an External Border Gateway Protocol (English: External Border Gateway Protocol, EBGP for short) session with the BR of the second AS, and issue a Border Gateway Protocol (English: EBGP)...
