Abstract

NXM queuing system in switching system contains N input ends and M destination ends. There are switching unit, flow controller and system central dispatcher. Characters are: (1) queuing data packets in two stages is carried out in storage buffer area at input end; at first stage, based on priorities, data packets reached to each input end in system are sorted to L classes, L is a positive integer larger than 1 given in advance; (2) based on each class, queuing is carried out according to destination; (3) through simple and effective dispatch algorithm, data packets in queues in first stage are sent to queues in second stage according to priorities of destination ends; (4) under control of quick dispatch of central dispatcher, data packets through switching unit reach to destination end of the system. The invention supports quality of service, lowers difficulties of bottleneck of central dispatch. The method is applicable to high-speed router in large scale and other switchboard.

Description

Technical field

[0001] The invention relates to a method for controlling data packets flowing through a network communication system, in particular to a method for a two-stage queuing structure at the input end of a switching system. Background technique

[0002] At present, the information network is developing at an extremely rapid rate. The data flow on the Internet is increasing at a rate of 30% per month. The amount of information transmitted on the information network is already astronomical, and the development of the next generation network The overall trend is bound to be the rapid growth of bandwidth and the continuous improvement of speed. The switching capacity of the core router, the central node, will inevitably increase by tens to hundreds of times; on the other hand, the level of human use of information networks is constantly deepening. , Users' requirements for service quality are also rapidly increasing. In recent years, service quality assurance has become a m...
