Transmission rate control method and device based on cross-data center network communication

Abstract

The invention relates to the technical field of network communication, in particular to a transmission rate control method and device based on cross-data center network communication. The method comprises the following steps: firstly calculating the bandwidth utilization rate of each data center link at a historical sending rate, then calculating the change information of each bandwidth utilization rate in a period of time, and finally obtaining the bottleneck position of the whole link network according to the change information and the bandwidth utilization rate. In other words, whether the bandwidth utilization rate of the data center link is close to the bottleneck bandwidth utilization rate of the data center link or the bandwidth utilization rate of the wide area network link is close to the bottleneck bandwidth utilization rate of the wide area network link is judged, and then the sending rate can be adjusted in a targeted mode so as to prevent the whole link network from being congested. According to the invention, the sending rate can be adjusted before congestion occurs so as to avoid congestion, and the bandwidth utilization rate of the whole link network can be maximized by adjusting the sending rate while congestion is avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a transmission rate control method and device based on cross-data center network communication. Background technique [0002] Cross-data center network communication means that two or more data center links communicate through WAN links. Regardless of the bandwidth utilization of the data center links or the bandwidth utilization of the WAN links, network congestion will occur. [0003] In order to effectively utilize network bandwidth resources, reduce network congestion, and improve user experience, a large number of congestion control algorithms have been proposed to effectively control the transmission rate. By controlling the transmission rate within an appropriate range, the communication efficiency of the entire network can be improved. Reduce network congestion. In order to achieve the above purpose, the packet loss information and delay information in the ...
