AI Technical Summary

Technical Problem

In existing data center network systems, node devices cannot accurately identify congested nodes, making network optimization difficult, and lossless Ethernet technology is difficult to promote and deploy in existing data center networks.

Method used

The source node sends detection messages carrying device numbers and message transmission statistics. Intermediate nodes prioritize processing and forwarding these messages, and the destination node calculates network congestion and locates congested nodes, thus achieving accurate network congestion detection and location.

Benefits of technology

It eliminates the need for intermediate nodes to have congestion detection capabilities, accurately quantifies network congestion levels, and quickly locates congested nodes, providing data support for network optimization and improving network operation and maintenance capabilities.

Abstract

The present application relates to the field of communication technology, and provides a network congestion detection and congestion node positioning method and network system. A source end node sends a first type of detection packet and each second type of detection packet of a current detection period to a destination end node; each intermediate node caches the received first type of detection packet to a highest priority sending queue, and determines the priority of the received second type of detection packet and caches to a corresponding sending queue; the destination end node obtains first packet reception statistical data when receiving the first type of detection packet of the current detection period, and calculates network congestion degree in combination with packet sending statistical data in the first type of detection packet; and also obtains second packet reception statistical data when receiving the second type of detection packet of the current detection period, and determines a congestion node in combination with network congestion degree, packet sending statistical data and equipment number in the second type of detection packet. The network congestion degree is accurately quantified and the congestion node is quickly positioned.
