AI Technical Summary

Technical Problem

Existing RoCE technology suffers from slow congestion awareness feedback and isolated processing, resulting in low bandwidth utilization and difficulty in responding promptly to rapidly changing network environments.

Method used

A burst congestion sensing mechanism based on reverse explicit notification and a progressive congestion sensing mechanism based on lightweight traffic prediction are adopted, combined with a fusion congestion control method of fast deceleration and fast recovery. The congestion and recovery notifications are sent directly in reverse by the switch, and the sender performs active prediction and rate adjustment to achieve unified rate control.

Benefits of technology

It enables timely congestion awareness, avoids rate oscillations, improves bandwidth utilization and network stability, and significantly increases throughput and flow completion time.

Abstract

本发明属于计算机网络技术领域,具体涉及一种基于反向显式通知与轻量化流量预测的拥塞控制方法,应用于RoCE网络。包括:交换机端基于反向显式通知的突发拥塞感知机制,发送方端基于轻量化流量预测的渐进式拥塞感知机制,以及快速减速和快速恢复的融合拥塞控制机制;在交换机处直接生成拥塞通知并反向发送给发送方,发送方端通过主动测量来实现前瞻性的拥塞感知;所述快速减速和快速恢复的融合拥塞控制机制,收到拥塞通知帧时执行乘性减少,或预测拥塞时执行渐进减速,收到恢复通知帧时执行乘性增加恢复,无事件时维持缓慢增速。本发明实现了及时准确的拥塞感知、高带宽利用率和低速率震荡,相比传统方法性能显著提高。
