Embodiment Construction

[0036] The working process of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0037] first reference figure 1 As shown, the present invention is realized based on a trusted routing model, and the trusted routing model includes an intelligent service identification and flow control module, a packet queue and weighted scheduling module, and a QOS routing algorithm module, wherein the intelligent service identification and flow control The module conducts intelligent service identification and identification for the packets arriving at the border router, and identifies different DSCP marks for different services; the packet queue and weighted scheduling module is responsible for entering different services into active queues with different priorities according to their DSCP values, and then according to the The weighted round-robin scheduling algorithm performs scheduling and adjusts the appropriate rate; the QOS...

Abstract

The invention discloses a selection method of distributed QOS (Quality of Service) routes, which comprises the following steps of: (1) marking a DSCP (Differentiated Services Code Point) value for a subgroup according to the service type of the subgroup, sending a plurality of explorer packets with the same request number to a middle node at the same time, and starting the parallel search of parallel routes; (2) judging the type of the arrived explorer packets by the middle node, and specifically processing the explorer packets; and (3) creating an explorer packet buffer list by a target node according to the subgroup condition of the arrived explorer packets, and realizing the storage and the reservation of the parallel routes. The routing method can meet the varying requirements of the multimedia service, not only has the advantages of simple distributed route algorithm and low link expense, but also can reduce resource fragments produced when the network is heavily loaded so as to accept more services.

Description

technical field [0001] The invention is a distributed QOS routing method based on intelligent service classification, adopts a distributed routing technology based on selective detection, relates to the application of a trusted routing framework based on intelligent service identification, and belongs to the technical field of QOS routing. Background technique [0002] With the rapid development of network multimedia technology, the Internet has gradually evolved from a single data transmission network to an integrated transmission network for data, voice, images and other multimedia information. Traditional networks that provide best-effort services are no longer able to meet the different requirements of various applications for network transmission quality. The endless multimedia applications put forward higher requirements for the service quality of the network. These different applications have different QOS (Quality Of Service) requirements. QOS is usually measured b...
