Embodiment Construction

[0017] figure 1 It is a flow chart of Embodiment 1 of the message cross-card forwarding method of the distributed router of the present invention, as shown in figure 1 As shown, the method of this embodiment may include:

[0018] Step 101, the ingress line card performs ingress service processing on the message according to the ingress service type corresponding to the port receiving the message, and determines the port of the egress line card of the message according to the routing table; wherein, the ingress line card and the egress line card are different line cards on the same router;

[0019] Step 102, the ingress line card determines whether the ingress line card can perform egress business processing on the message according to the egress service type corresponding to the port of the egress line card, and if so, the ingress line card determines according to the egress service type of the egress line card The business type performs egress business processing on the mes...

Abstract

The present invention provides a distributed router message cross-card forwarding method and device, a distributed router message cross-card forwarding method, when the entry line card is determined according to the export service type corresponding to the port of the exit line card When the ingress line card performs egress service processing on the message, the ingress line card performs egress service processing on the message according to the egress service type, and processes the egress service-processed message according to the adjacency table Ethernet protocol encapsulation, and send the encapsulated message to the egress line card through the Ethernet network, so that the egress line card sends the message to the network through the port of the egress line card, avoiding the export The CPU of the line card is queued for processing packets, and the CPUs of the ingress line card and the egress line card are prevented from performing encapsulation or decapsulation processing based on the PCIE protocol respectively, thereby improving the forwarding performance of the router.

Description

technical field [0001] The invention relates to communication technology, in particular to a message cross-card forwarding method and device of a distributed router. Background technique [0002] With the rapid development of the network, the services carried by the network are also developing rapidly, and the requirements for routers are also getting higher and higher. The distributed router based on multi-core can make full use of its parallel processing ability to improve the forwarding performance of the router. [0003] In the prior art, since there are multiple service line cards in the distributed router, the message will be sent to the network through the output port of a service line card according to the established routing policy. In this way, there are two scenarios. One is that the output port is on the ingress line card, and such forwarding is called intra-card forwarding; the other is that the output port is not on the ingress line card, so cross-card forward...
