Network bandwidth updating method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a network bandwidth updating method and device, electronic equipment and a storage medium. The network bandwidth updating method comprises the steps of obtaining a plurality of historical bandwidths of a network when the network is detected to be recovered from a congestion state, determining a reference bandwidth according to the plurality of historical bandwidths, and probing the network with a reference bandwidth to update the bandwidth of the network. According to the embodiment of the invention, the historical bandwidth represents the bandwidth level reached by the network before congestion; a reference bandwidth is determined according to the historical bandwidth; with the reference bandwidth as the reference detection bandwidth, the processof bandwidth up-detection to the normal available bandwidth can be shortened, the problem of long bandwidth detection time consumption caused by taking a smaller bandwidth as a reference detection bandwidth when the network is in a congestion state is solved; the bandwidth of the network can be quickly recovered to the bandwidth before congestion, even a higher bandwidth can be achieved, the network can transmit data with a higher bandwidth in a shorter time after congestion recovery, and the transmission efficiency of user data is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer networks, and in particular to a network bandwidth updating method, device, electronic equipment and storage medium. Background technique [0002] In recent years, with the huge increase in the number of Internet users, the emergence of new network and computing technologies, new business applications and business models has put forward higher requirements for the performance of the Internet. In actual network scenarios, the network goes through the process from normal to congestion and back to normal from congestion, and the network bandwidth also increases and decreases synchronously. [0003] In the traditional congestion control algorithm, one way is to use the sliding window mechanism based on Additive Increase Multiplicative Decrease (AIMD) under the TCP data transmission protocol to detect and update the available bandwidth of the network. Slow down the sending r...
