Abstract

The invention provides a network congestion control method, a network congestion control device and a network congestion control system. The method comprises the following steps of: monitoring data traffic of all service nodes in a distributed network; when the monitored data traffic of one or more service nodes exceeds a preset congestion threshold value, sending load balancing instructions and routing tables of idle service nodes to all the service nodes; and sharing the data of the congestion service nodes by the idle service nodes according to the load balancing instructions. By sharing the data of the congestion service nodes to the idle service nodes to balance the load of the congestion service nodes, congestion control of an application layer is realized, the congestion control efficiency is improved, meanwhile, the defect of data loss of the application layer in the prior art is avoided, the data integrity is improved, and the stability of each service system in the distributed network is further improved.

Description

technical field [0001] The invention relates to the field of business support, in particular to a network congestion control method, device and system. Background technique [0002] There are roughly four congestion control mechanisms currently used on network devices, namely: slow start, congestion avoidance mechanism, fast retransmission, and fast start. Among them, the principle of slow start is: when the host enters the transmission, it first accesses the network at a slower speed, and then gradually increases the transmission rate according to the judgment of the network situation until it reaches congestion. This method only prevents the host from directly entering the congestion state after accessing, and cannot effectively control the congestion, and cannot support time-sensitive services. The congestion avoidance mechanism is to monitor the network data, and when the data flow reaches a certain threshold, it starts to send a response to the data sender, so that the...
