Problems solved by technology

The transmission speed and quality of the network are limited by link bandwidth and other factors. When the network is busy, network communication will cause performance degradation due to link congestion, such as packet loss, data transmission rate drop, etc.
[0003] At present, the communication path determination method based on software-defined network usually selects the communication path after the communication path is congested. Although this method has played a certain role, it cannot respond quickly. The quality of network communication and transmission speed still cannot be effectively improved

Abstract

The invention provides a communication path determination method and device, and the method comprises the steps of obtaining the to-be-sent data, and determining a target terminal based on the targetterminal information carried by the to-be-sent data; determining a target software defined network where the target terminal is located, and obtaining the state information of each switch in the target software defined network; based on the state information, respectively determining a topological structure of a target software-defined network, an available bandwidth of each link in the target software-defined network and a bandwidth utilization rate of each link in the target software-defined network; and determining a target communication path based on the topological structure, the available bandwidth and the bandwidth utilization rate. Compared with the prior art, by determining the bandwidth utilization rate and the available bandwidth of each link in the target software-defined network, determining whether the link is the congested link or not, and selecting the smooth link as the communication path, the use of the congested link is avoided, and the communication speed and quality are improved.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a method and device for determining a communication path. Background technique [0002] With the continuous development of life and work, people have higher and higher requirements for network information transmission. Among them, network data transmission speed and transmission quality are two particularly important aspects in network information transmission. The transmission speed and quality of the network are limited by link bandwidth and other factors. When the network is busy, network communication will cause performance degradation due to link congestion, such as packet loss and data transmission rate drop. [0003] At present, the communication path determination method based on software-defined network usually selects the communication path after the communication path is congested. Although this method has played a certain role, it cannot re...
