Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055]At present, the commonly used congestion control schemes have insufficient perception accuracy of network congestion, resulting in poor congestion control effects. For this reason, in some embodiments of the present application: hardware time is used to record the sending time and receiving time experienced by the target data packet and its corr...

Abstract

The embodiment of the invention provides a network congestion control method and equipment. In the embodiment of the invention, the sending time and the receiving time experienced by the target data packet and the corresponding acknowledgement data packet in the single communication round trip are recorded by adopting the hardware time, so that the network time delay can be calculated according to each hardware time, and the network congestion can be sensed and the network rate of the home terminal can be adjusted based on the network time delay. In the embodiment of the invention, the network time delay is calculated based on the hardware time, so that the accuracy of the network time delay can be effectively improved, the network congestion can be sensed more accurately according to the network time delay, the network rate of the home terminal can be adjusted according to the network time delay, and more accurate congestion control is realized.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a network congestion control method and device. Background technique [0002] In recent years, users' demand for data centers and cloud computing services has grown rapidly, and higher performance requirements have been put forward. Among them, the network has an important impact on the performance of data centers and cloud computing services, and network congestion will seriously affect the performance of data centers and cloud computing services. [0003] At present, commonly used congestion control schemes include CUBIC (cubic) scheme based on packet loss, DCQCN (data center quantized congestion notification) scheme based on network marking, etc. However, the perception accuracy of these congestion control schemes on network congestion Insufficient, leading to poor effect of congestion control. Contents of the invention [0004] Various aspects of the present ap...
