Network congestion control method and device for alarm network

Abstract

The invention provides a network congestion control method and device for an alarm network and aims to reduce network congestion of the alarm network and improve sending timeliness and accuracy of an alarm event in the alarm network. According to the network congestion control method, a present network state, an optimal network state and at least one network state empirical value determined according to rules of the sending quantity of alarm events, a network congestion generation probability assessment value at the present time is determined, interval division of the probability assessment value is carried out, intervals respectively correspond to different alarm event sending mechanisms, and a corresponding alarm event mechanism is started according to a value of the determined probability assessment value. Through the method, network congestion is reduced, and an alarm event with a relatively high emergency level is preferably guaranteed to send firstly when the network is liable to generate network congestion.

Description

technical field [0001] The invention relates to the communication field, in particular to a network congestion control method and device for an alarm network. Background technique [0002] Video surveillance is an important part of the security system. In recent years, with the rapid development of computers, networks, image processing, and transmission technologies, video surveillance technology has also made great progress, and has become a real-time monitoring tool for key departments or important places in various industries. physical basis. During the application process, the alarm network of video surveillance has very high requirements for bandwidth stability. If it is not handled properly, there will be problems such as mosaics, screen jumps, and pauses in the video screen, which will affect the monitoring effect; For services with particularly high bandwidth requirements, in a certain period of time, if a large number of alarm triggers occur in the alarm network at...

Problems solved by technology

During the application process, the alarm network of video surveillance has very high requirements for bandwidth stability. If it is not handled properly, there will be problems such as mosaics, screen jumps, and pauses in the video screen, which will affect the monitoring effect; For services with particularly high bandwidth requirements, in a certain period of time, if a large number of alarm triggers occur in the alarm network at the same time, the bandwidth demand of the alarm network will exceed the upper limit of the bandwidth for a period of time, resulting in congestion, seriously reducing the transmission efficiency of alarm events and even Deadlock occurs
