Problems solved by technology

[0005] The problem in the above scenario is that after the router (ISR or ASR) starts the learning function, it will learn all the packets of each user to resolve the mapping information to the source address of the packet, so that the return packets can be forwarded directly. Improve forwarding efficiency, but learning each message also affects forwarding performance

Abstract

The invention discloses a method for forwarding a message and is applied a receiver router. The method includes the steps of finding the corresponding receiver router address in the local mapping table according to the address of a receiver of the message to be sent, and tunneling and sending the message to the receiver router if the receiver router address is found, wherein the message carries the indication information indicating that the receiver router does not need to learn the sender address mapping information. The method can optimize the learning function of a router on message source addresses, thereby improving forwarding performance. The invention further discloses an apparatus for forwarding a message.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for forwarding messages. Background technique [0002] Such as figure 1 As shown, in the identity and location separation network, UE (User Equipment, user equipment) configures AID (Access Identification, access identification) as an identity identifier, and ASR (Access Service Router, access service router) configures RID (Router Identifier, router ID) as a location identifier, the basic functions of ILR (Identification & Location Register, identity and location registration register) include: management and maintenance of mapping information between AID and RID. [0003] In the network where the identity and location are separated, when the user equipment UE1 goes online on the access service router ASR1, it sends a data message to access the service application program APP1 attached under the ISR (Interconnection Service Router, Interconnect...
