Network equipment and message transferring method based on multiple-core processor

Abstract

The invention relates to a network device, and a report transfer method based on multi-core processor. Wherein, said network device comprises: classifying unit and transfer processor with multi-core unit; the classifying unit receives report at any port of network device, selects core unit from the transfer processor, and sends received report to selected core unit; one core unit of transfer processor transfers report when receives report. The invention can use classifying unit to select core unit to balance the load between core units, to make them parallel transfer reports, to improve the report transfer ability of network device.

Description

technical field [0001] The invention relates to network communication technology, in particular to a network device and a message forwarding method based on a multi-core processor. Background technique [0002] During network communication, when a network device with a router function (for convenience of description, the network device with a router function is referred to as a network device for short below) receives a message, it performs a process on the message according to the address information in the message header. A series of forwarding processing, such as forwarding-in processing, table entry lookup processing, and forwarding-out processing. [0003] With the continuous development of communication services, network devices often need to forward and process a large number of packets at the same time. In this way, it is required that the network equipment must have a relatively high processing capability. [0004] FIG. 1 is a schematic diagram of the internal str...

AI Technical Summary

Problems solved by technology

However, this method has the following disadvantages: when a network device receives a large number of packets on one or several physical ports of itself, but does not receive packets or receives a small amount of packets on other physical ports, it will One or several CPUs in the network device need to perform a large amount of message forwarding processing, and the processing speed cannot meet the message forwarding processing requirements, while other CPUs are in an idle state. Therefore, the load among the CPUs is unbalanced. The packet forwarding and processing capabilities of network devices cannot be effectively improved, so that the packet forwarding processing of network devices cannot be fundamentally guaranteed
