Jamming control method and device

Abstract

The invention discloses a congestion controlling method which is applied to a network technique field and comprises: packet identifiers that are corresponding to the packet slicing which is discarded in the process of random early testing and processing are extracted; the packet slicing with the same packet identifier is discarded. Internetwork protocol identifiers can be taken as the packet identifiers or adding identifiers; internetwork protocol identifiers or adding identifiers which are corresponding to the packet slicing which is discarded in the process of random early testing and processing are extracted; the extracted identifiers are compared with identifiers of subsequent packet slicing and if the identifiers are the same, the packet slicing are discarded, and if not, are retransmitted continuously. A receiving end receives and reorganizes the received packet slicing and when the reorganization goes wrong, retransmission is requested. The invention also discloses a congestion controlling device. The utilization of the invention can discard the useless relevant packet slicing in advance, thus alleviating the load of network devices, reducing the resource utilization rate, saving bandwidth and further ensuring high effectively carrying out other sessions without discarding packets.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a congestion control method and device. Background technique [0002] Data packet forwarding in the network generally needs to go through one or more intermediate processing devices, and these data packets need to occupy certain resources of the intermediate processing device when being forwarded, such as cache, bandwidth, processing capacity, etc. figure 1 It shows the data path of data packet forwarding in the network, including the sending end, the intermediate processing device and the receiving end. When there are a large number of data packets that need to be forwarded in the network, the data packets cannot be forwarded due to insufficient resources, such as insufficient cache, insufficient available bandwidth, or limited processing capacity, and congestion occurs. [0003] When congestion occurs, the data packets waiting to be processed in the data packet queue ...

Problems solved by technology

Such a vicious cycle will cause the router to shut down and restart in serious cases, and after restarting, it will face a sudden retransmission impact

As long as its load cannot be effectively improved, the downtime and restart will continue to repeat. In this way, the router will be completely paralyzed and unable to work, and the network will also be greatly shaken
