Network congestion control method and device and computer readable storage medium

Abstract

The invention discloses a network congestion control method and device and a computer readable storage medium, and the method applied to a switch comprises the steps: obtaining a congestion control message from a destination end device, transmitting the congestion control message to a corresponding source end device, obtaining a first data message from the source end device, determining that the source end equipment does not respond to the congestion control message according to the message rate for acquiring the first data message, and performing congestion control management on the first data message acquired from the source end equipment. Based on the embodiment of the invention, the situation that the congestion control message sent by the target end equipment cannot obtain the response of the corresponding source end equipment can be judged, so that the switch can perform congestion control management on the data message obtained from the source end equipment, thereby reducing network congestion and avoiding the forwarding performance degradation of the switch.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of network technologies, and in particular, relate to a network congestion control method, a switch, a congestion control device, and a computer-readable storage medium. Background technique [0002] In the application scenarios of high-performance computing, distributed storage, and artificial intelligence, data center switches face high concurrency and high burst traffic, which puts forward higher and higher requirements for the performance of switches. In order to achieve zero packet loss in order to ensure business continuity. If the source end does not respond in time or cannot respond in the process of congestion processing, it will cause serious failures in network services. [0003] However, in related technologies, the scenario that the source device cannot respond in time or cannot respond to the congestion control message is not considered. Once the source devic...

If the source end does not respond in time or cannot respond in the process of congestion processing, it will cause serious failures in network services

[0003] However, in related technologies, the scenario that the source device cannot respond in time or cannot respond to the congestion control message is not considered. Once the source device cannot respond in time or cannot respond to the congestion control message for some reason, it will cause the destination device to The device continuously sends congestion control packets

In a complex network, a large number of congestion control packets cannot be processed in time, which will directly affect the forwarding performance of network devices such as switches in the middle
