Problems solved by technology

[0004] Further, if the routing control policy changes, the BGP router needs to resend the BGP route to the BGP peer, and the BGP router will filter the BGP route through the changed routing control policy, and send an update message to the BGP peer. text; but the sending of the update message will increase the burden on the link and increase the loss of the CPU (Central Processing Unit, central processing unit)

Embodiment Construction

[0051] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] The embodiment of the present invention proposes a method for sending packets based on a routing control strategy, which is applied to a network including a BGP routing switching device (such as a BGP router, which will be described later using a BGP router as an example) and a BGP peer, and BGP routers and BGP peers are relative; figure 1 It is a schematic diagram of an application scenario of the embodiment of the present invention, BGP router B and BGP router C are BGP peers of BGP router A, and BGP router A is a BGP peer of BGP router B, and BGP router A is a BGP peer of BGP router C BGP peers.

[0053] It should be noted that if the BGP router is configured with a route control strategy for sending BGP routes to the BGP peer, then perform the subsequent process of the embodiment of the present invention; if the BGP router is not configured...

Abstract

The invention discloses a message sending method and equipment based on a route control strategy. The message sending method comprises the steps that whether processed BGP (border gateway protocol) route attributes obtained before and after the control strategy is changed are identical or not is judged by BGP route switching equipment; if not, update messages are sent to BGP peers by the BGP route switching equipment; and if yes, the BGP route switching equipment rejects to send the update messages to the BGP peers. By adopting the message sending method and equipment, burdens of links can be reduced, the safety of the links can be improved and losses of a CPU (central processing unit) can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for sending messages based on routing control strategies. Background technique [0002] Routing control strategy is a technology for modifying routing information in order to change the path through which network traffic passes, mainly by changing routing attributes (including reachability); among them, the application of routing control strategy includes: (1) Controlling the release of routes: When the routing protocol publishes the routing information, it filters the routing information through the routing control strategy, and only publishes the routing information that meets the conditions; (2) Controlling the reception of the route: when the routing protocol receives the routing information, it uses the routing control strategy to filter the routing information. Filtering, only receive routing information that meets the conditions; (3) Manage impor...
