基于网络包延迟偏差的硬件动态拥塞控制机制
A hardware dynamic congestion-control mechanism based on packet delay variation
摘要
Abstract
Interconnection networks have become a technical bottleneck to improve the performance of high-performance computing systems.The congestion control in high-performance interconnection networks is studied.Aiming at the formation process of communication hotspots,a hardware dynamiccongestion control mechanism (CMDPD) is proposed.The transmission delay variation of packets is used to predict the network congestion state,and the end-to-end network injection is controlled to avoid the network congestion.The simulation environment is built up,and CMDPD is simulated under Fattree and Dragonfly networks.The results show that the throughput of CMDPD in Fat-tree network is improved by 5％～ 12％.关键词
