Title:

METHOD AND DEVICE FOR CONGESTION CONTROL, COMMUNICATION NETWORK, AND COMPUTER STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2020/253488

Kind Code:

A1

Abstract:

The present application relates to the technical field of networks. Disclosed are a method and device for congestion control, a communication network, and a computer storage medium. A network device first acquires statistical information of a target egress queue during a first period, the target egress queue being any egress queue in the network device; and then determines an explicit congestion notification (ECN) waterline of the target egress queue during a second period on the basis of the statistical information of the target egress queue during the first period, the second period being chronologically subsequent to the first period. During the second period, when the queue depth of the target egress queue exceeds the ECN waterline, the network device configures an ECN marker for data packets in the target egress queue. The present application implements the dynamic adjustment of the ECN waterline of an egress queue via the network device, thus increasing the flexibility of network congestion control.
