Model tracking network congestion control method

Abstract

The invention relates to a model tracking network congestion control method. The method comprises the following steps of a, a control end sends messages to receiving ends in a timed mode to query the network packet loss of a current network system; b, the control end waits for and receives the network packet loss feedback information of the receiving ends; c, the control end determines whether the network packet loss feedback information is received; d, the control ends determines whether the current network packet loss is a network congestion mode according to the feedback information, if so, performs the step e, and if not, closes a congestion control mechanism and returns to the step b; e, the control ends starts the congestion control mechanism, enters a step of model tracking network control and transmits control instructions to the receiving ends to adjust the receiving states of the receiving ends. Compared with the prior art, the model tracking network congestion control method has the advantages of enhancing the stability of network channels, reduces network packet losses to the maximum degree, achieves low costs and the like.

Description

technical field [0001] The invention relates to a network control method, in particular to a model tracking network congestion control method. Background technique [0002] The network is a huge nonlinear system, the resources in the network are shared by more and more users, and the problem of network congestion becomes more serious. Network congestion control belongs to the interdisciplinary field of computer science, optimization theory and control theory. The key issues in the design of congestion control algorithms are how to generate feedback information and how to respond to the feedback information. [0003] The root cause of network congestion is that the load provided by users (end systems) to the network is greater than the capacity and processing capacity of network resources, which manifests as increased packet delay, increased number of discards, and decreased performance of upper-layer application systems. [0004] In the original TCP protocol, there is only...

[0003] The root cause of network congestion is that the load provided by users (end systems) to the network is greater than the capacity and processing capacity of network resources, which is manifested as increased packet delay, increased number of discards, and decreased performance of upper-layer application systems.

[0004] In the original TCP protocol, there is only flow control (Flow Control), but no congestion control (Congestion Control). The receiving end uses the TCP header to notify the sending end of the receiving capacity. This control mechanism only considers the receiving capacity of the receiving end, but does not consider The transmission capacity of the network leads to the occurrence of network congestion collapse (Congestion Collapse)
