Abstract

The embodiment of the invention provides a table entry management method and device, and relates to the field of communication. According to the table entry management method and device, after forwarding cores find that forwarding table entries corresponding to source MAC addresses in data flow do not exist, and when no table entry records corresponding to the data flow are found, the characteristic information of the data flow used for creating the table entries is stored into a free storage unit of a local cache and meanwhile is added into a preset message queue, and then control cores are notified, so that the control cores can create corresponding forwarding table entries according to the characteristic information of the data flow in the preset message queue. The table entry management method and device have the advantages that the data flow for repeatedly learning the MAC addresses is filtered out, the table entry learning efficiency is improved, the arithmetic logic of the forwarding cores is relieved, and the forwarding performance of the table entry management device is improved.

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,...
