Switch message congestion processing method and device, and storage medium

Abstract

The invention discloses a switch message congestion processing method. The method comprises the following steps: receiving a message through a port of the switch; detecting the occupancy rate of a cache space of the port; forwarding the message to an external memory in response to the occupancy rate reaching a preset rate; after a preset time period, continuing to detect the occupancy rate of thecache space of the port; and in response to the fact that the occupancy rate of the cache space of the port is smaller than the preset rate, sending a message meeting a preset condition in the external memory to the switch, and forwarding the message through a corresponding output port in the switch. The invention further discloses computer equipment and a readable storage medium. According to thescheme provided by the invention, by caching the forwarded and congested message and then forwarding the message out in a non-congested state, the traffic congestion condition of Ethernet switch equipment during forwarding can be relieved.

Description

technical field [0001] The invention relates to the field of message processing, in particular to a processing method, device and storage medium for message congestion of an exchange. Background technique [0002] Network data in the data center, with the development of AR (Augmented Reality), VR (Virtual Reality), AI (Artificial Intelligence), video and other business applications, the data to be processed has increased significantly, and the capacity of the main network equipment switches in the data center Although the rapid increase, due to the uncertainty of the business, there is a large amount of burst traffic in the data center network, and the traffic will be congested in an instant, exceeding the bandwidth of the switch device port, resulting in packet loss and affecting the normal processing of the business. [0003] In the current technical solution, the on-chip cache of the switching device is generally used to cache the congested packets, and continue to send t...

Problems solved by technology

However, general switching devices have a relatively high integration level, and it is difficult to integrate a large on-chip cache, which is basically between a few MB and tens of MB. Compared with the switching capacity of several Tb to tens of Tb of the current switch, the data that can be cached is very small , the on-chip cache will be fully occupied in the congestion time of about 10us, so the congestion in most scenarios cannot be solved
