Abstract

The present application provides a network congestion control method and device, wherein the method includes: determining whether network congestion occurs in the target network; determining whether network congestion occurs at the last hop in the case of determining network congestion; In the case of the last hop, the sending window is dynamically adjusted through the PID controller for congestion control. The above-mentioned method solves the problem of high implementation cost and large delay of existing network congestion, and achieves the technical effect of high-efficiency, low-delay and low-cost congestion control.

Description

technical field [0001] The present application belongs to the technical field of data storage, and in particular relates to a network congestion control method and device. Background technique [0002] The data center is mainly used in different types of high-performance computing and distributed data storage services. The expansion of these usage scenarios has brought great pressure to the data center, and it is necessary to provide a faster throughput at a low cost. volume and extremely low latency by the way. More specifically, with the trend of deploying high-speed I / O storage media in data centers, such as the Non-Volatile Memory Host Controller Interface Specification (NonVolatile Memory Express, NVMe), both storage speed and access latency have been significantly improved. improve. Therefore, data centers are increasingly suitable for hosting applications that require huge computing and storage capacity, such as data mining and large-scale machine learning. [0003...
