Abstract

The embodiment of the invention discloses a method, device and system for controlling network congestion, and belongs to the technical field of big data. The method comprises the steps that a transferdevice receives a target token request sent by a data sending end and sends the target token request to a data receiving end, and the data receiving end can determine a target token packet corresponding to the target token request according to the target token request and then send the target token packet to the transfer device according to a priority identifier. After the transfer device receives the target token packet, the transfer device can determine the sending rate of the token packet according to the link bandwidth of the transfer device, the preset packet length of the token packet and the preset packet length of the data packet, and then send the target token packet to the data sending end according to the priority identifier and the sending rate of the token packet. After receiving the target data packet sent by the data sending end, the transfer equipment can send the target data packet to the data receiving end. According to the invention, the packet loss rate can be reduced.

Description

technical field [0001] The present application relates to the field of big data technology, in particular to a method, device and system for controlling network congestion. Background technique [0002] With the rapid development of Internet technology, huge data and information processing requirements have been brought, so that more and more data is concentrated in the data center network for processing. [0003] In related technologies, the congestion control method is generally as follows: the data sending end can collect congestion signals, and dynamically adjust the congestion control window of the data sending end through the congestion signals, thereby adjusting the sending rate of data packets. For example, the data sender can detect the RTT of each data packet, estimate the queuing delay in the network based on the RTT, reduce the sending rate of data packets when the queuing delay increases, and increase the sending rate of data packets when the queuing delay decre...
