Problems solved by technology

[0003] However, in the above two methods in the prior art, the next hop on the BGP forwarding path of the data packet is calculated through the default BGP route, such as the path vector routing protocol, which is less flexible.

Embodiment Construction

[0063] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0064] 1. Autonomous system (autonomous system, AS)

[0065] AS refers to an interconnected network, which divides the entire Internet into many smaller network units, and these small networks have the right to independently decide which routing protocol should be used in this system.

[0066] like figure 1 as shown, figure 1 AS1, AS2 and AS3 in the Internet are shown.

[0067] It should be noted, figure 1 2 only schematically shows the above three ASs in the Internet, and the Internet may also include other numbers of ASs, for example, 1, 2 or more than 3 ASs, which is not limited in this embodiment of the present application.

[0068] 2. Router

[0069] The router is the main node device of the Internet, and the router determines the forwarding of data through routing.

[0070] According to ...

Abstract

The invention provides a routing control method and device, is applied to the field of communication, can determine forwarding path information of a data message according to requirements met by a specified BGP forwarding path, and is higher in flexibility. The routing control method comprises the following steps: a first edge routing node receives a border gateway protocol (BGP) control message,the BGP control message carries a first node identifier and first algorithm information, the first node identifier indicates an SID of a destination routing node on a BGP forwarding path, the first algorithm information indicates a demand satisfied by the BGP forwarding path, wherein the first algorithm information indicates an SID of a destination routing node on the BGP forwarding path, the BGPforwarding path comprises a routing node through which a data message is routed to the destination routing node through the first edge routing node, the first edge routing node belongs to a first autonomous domain AS, and the destination routing node belongs to a second AS; the first edge routing node determines forwarding path information of the data message according to the first node identifierand the first algorithm information in the BGP control message, and the forwarding path information is used for indicating a next hop routing node of the data message; and the first edge routing nodeforwards the data message according to the forwarding path information.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a routing control method and device in the communication field. Background technique [0002] In label switching (multi-protocol label switching, MPLS) segment routing (segmentrouting, SR) or the sixth version of SR (SRv6), it is stipulated that the segment identification including the border gateway protocol (border gateway protocol, BGP) prefix (prefix) (identifier, SID) messages can be forwarded in the following two ways: Mode 1: push into the BGP prefix SID list in the MPLS stack of the data packet (or in the extended routing header (segment routing header, SRH) header of SRv6), The BGP prefix SID list includes the BGP prefix SID (BGP Prefix-SID) of at least one edge routing node that the data packet forwarding process passes through in turn, and the data packet follows the BGP Prefix of the edge routing node in the BGPprefix SID list. -SID forwarding; mode 2: pu...
