List item management method and device

Abstract

Embodiments of the present invention provide an entry management method and device, which relate to the communication field. After the forwarding core searches for the forwarding entry corresponding to the source MAC address in the data flow that does not exist, and when the entry record corresponding to the data flow is not found, the characteristic information of the data flow used to create the entry is stored into the free storage unit of the local cache, and at the same time add the feature information of the data stream used to create the table entry into the preset message queue, and then notify the control core, so that the control core according to the preset Set the feature information of the data flow in the message queue to create a corresponding forwarding entry. Filter out the data flow of repeatedly learning the MAC address, improve the efficiency of table item learning, reduce the operation logic of the forwarding core, and thereby improve the forwarding performance of the table item management device.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for table item management. Background technique [0002] In the field of data communication, the multi-core distributed architecture is very mature. Compared with the single-core architecture, the multi-core architecture greatly improves the forwarding performance of the device. However, on a Layer 2 forwarding network, when there is a large amount of bursty traffic in the network, a large number of bursty flows flood into the device, resulting in poor device performance. Therefore, how to quickly learn MAC forwarding entries, improve the forwarding performance of the whole machine, and improve the stability of the whole network, Contents of the invention [0003] The purpose of the present invention is to provide a table item management method and device. The technical scheme that the present invention takes is as follows: [0004] In the first aspect,...
