Abstract

The invention discloses a congestion control method and device, a communication network and a computer storage medium, and belongs to the technical field of networks. The method comprises the following steps that: network equipment acquires statistical information of a target egress port queue in a first time period, wherein the target egress port queue is any egress port queue in the network equipment; and based on the statistical information of the target egress port queue in the first time period, a display congestion notification ECN waterline of the target egress port queue in a second time period is determined, the second time period being located after the first time period in time sequence. And in the second time period, when the queue depth of the target egress port queue exceedsthe ECN waterline, the network equipment sets an ECN mark for the data packet in the target egress port queue. According to the method, dynamic adjustment of the ECN waterline of the egress port queueis realized through the network device, so that the flexibility of network congestion control is improved.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to a congestion control method and device, a communication network, and a computer storage medium. Background technique [0002] Congestion control is an important method to improve network resource utilization and optimize network transmission quality. [0003] In current networks, congestion control is usually performed based on an explicit congestion notification (ECN) mechanism. [0004] Currently, the sending end and the receiving end implement communication by forwarding data packets through network devices. The process of network congestion control based on the ECN mechanism includes: the sender sends data packets supporting the ECN mechanism; the network device detects whether the queue depth of the port queue exceeds the preset ECN waterline (ECN threshold); when the queue depth of the outbound port queue When the ECN watermark is exceeded, the network de...
