电力通信中基于动态阈值的流量控制机制研究
Research on a Flow Control Mechanism Based on Dynamic Threshold in Power Communication
摘要
Abstract
InfiniBand Architecture (IBA) is defined as a switch-based interconnection technology with high bandwidth and low-latency,which is suitable for constructing high-speed networks for cluster systems and has been ratified as a new industry standard for the server I/O and inter-processor communication.An efficient flow control mechanism with dynamic job threshold for InfiniBand networks is propopsed.Unlike the existing static threshold methods,it dynamically sets threshold according to the recording traffic in a cycle of traffic monitoring on the link.Switch to traffic assessment is a dynamic and continuous process.The maximum burst value of each business flow to assess,dynamic adjustment of the table to set the appropriate threshold.It can improve the processing capacity,bandwidth utilization,transmission efficiency of network burst traffic and reduce the delay,blocking probability,mean queue length.The principle of Maximum Entropy (ME) is adopted as an effective methodology to analyze the new mechanism with the generalized exponential distribution(GE-Type) for modeling the inter-arrival times and service times of the input traffic.The simulation results show that it can achieve the effective control of traffic flow in the high performance computing network in power communication.关键词
