Abstract

The invention relates to the technical field of network communication, in particular to an ECN threshold configuration method and device. The method comprises the steps that target scene parameters of a target output port in a current traffic forwarding scene are acquired, and the scene parameters of one output port are parameters related to traffic forwarded through the output port; judging whether a target ECN configuration matched with the target scene parameter exists in an association relationship between a preset scene parameter and the ECN configuration or not; and if it is judged that target ECN configuration matched with the target scene parameter exists in the incidence relation between the preset scene parameter and ECN configuration, configuring an ECN threshold of the target output port based on the target ECN configuration.

Description

technical field

[0001] The present application relates to the technical field of network communication, and in particular to an ECN threshold configuration method and device. Background technique

[0002] With the increase of high-concurrency and low-latency services, the outbound ports of network devices (such as switches and routers) are prone to network congestion. Network congestion refers to the phenomenon that when the traffic received by a network device through the ingress port is much greater than the traffic sent through the egress port, a large number of packets are stranded (cached) in the egress queue (the queue corresponding to the egress port), which will affect the transmission time of packets. Network performance such as delay and throughput.

[0003] Currently, a static explicit congestion notification (English: Explicit Congestion Notification, abbreviation: ECN) configuration is commonly used to control network congestion. Specifically, the network devi...
