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 invention provides a method and a device of cross-card forwarding of a message of a distributed router. According to the method of cross-card forwarding of the message of the distributed router, when an inlet line card is determined to carry out export business processing on the message at the inlet line card according to an export business type corresponding to a port of an outlet line card, the inlet line card carries out export business processing on the message according to the export business type, Ethernet protocol packaging is carried out on the message subjected to the export business processing according to an adjacency list, and the packaged message is transmitted to the outlet line card through Ethernet, so that the message is transmitted to a network by the outlet line card through the port of the outlet line card, queuing in a processing process of the message on a CPU (Central Processing Unit) of the outlet line card is avoided, packaging or de-packaging processing based on a PCIE (Peripheral Component Interconnect Express) protocol, which is respectively carried out on the CPUs on the inlet line card and the outlet line card, is avoided, and the forwarding performance of the router is improved.

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...
