Description
Technical field
The present invention relates to the resource routing technology of bearer network in the internet (internet), particularly a kind of route selection method of striding independent operation network.
Background technology
Along with the continuous expansion of internet (Internet) scale, various network services are fallen over each other to emerge in large numbers, and advanced multimedia system also emerges in an endless stream.Because real time business is comparatively responsive to characteristics such as network transfer delay, delay jitters, when sudden high file transfer (FTP) being arranged on the network or contain the business such as hypertext transmission (HTTP) of image file, real time business will be subjected to very big influence; In addition, because multimedia service will take a large amount of bandwidth, so also will make and need guaranteed key business to be difficult to be transmitted reliably in the existing network.So, to be transmitted reliably for guaranteeing key business, various service quality (QoS, Quality of Service) technology is just arisen at the historic moment.The Internet engineering duty group (IETF, Internet Engineering Task Force) has proposed a lot of service models and mechanism, to satisfy the demand of QoS.What industry was relatively approved at present is to use integrated service (Int-Serv, Integrated Service) model at the access or the edge of network, uses differentiated service (Diff-serv, Differentiated Service) model at server.
The Diff-Serv model only ensures QoS by the measure of setting priority level, though this model has the high characteristics of line efficiency, but concrete effect is difficult to prediction, therefore, industry is that the Diff-Serv model of backbone network has been introduced an independently bearer control layer, set up the special Diff-Serv qos signaling mechanism of a cover, thereby set up a resource management layer specially, with the topological resource of supervising the network for the Diff-Serv network.This resource management Diff-Serv mode is called as the Diff-Serv of independent bearing control layer model.In this model, the bearer network Control Server is responsible for configuration management rule and network topology, is client's service bandwidth application Resources allocation.Transmit client's service bandwidth application request and result between the bearer network Control Server of each management domain by signaling, and explorer is the routing information of professional application distribution etc.
Shown in Figure 1 is the Diff-Serv model schematic diagram of independent bearing control layer, this Diff-Serv model can be divided into three layers according to function, be respectively: service control layer, bearer control layer and bearing bed, wherein, service control layer is made up of the service server that links to each other with subscriber equipment, and the subscriber equipment that sends data flow is by the bearer path of service server to bearer control layer application business; Bearer control layer is made up of several explorers (CM), be in charge of the Internet resources of bearing bed, comprise bandwidth, processor and buffer (Buffer) etc., carry out resource for every Packet data service application that the business that QOS requires arranged according to the situation of its qos requirement, destination address and current bearing bed and allow control, resource allocation and routing, satisfy the QOS requirement of Packet data service; Bearing bed is made up of edge router and core router, and it sends to the purpose subscriber equipment according to Internet resources and routing path bearer service that CM distributes with business.
But, because the CM management all is the edge router and the core router of the inner bearing bed of independent operation network in the bearer control layer, when the user of this independent operation network sends professional purpose user to other independent operation network, because present networks CM can't manage the edge router and the core router of other independent operation network, thereby can't determine the route of the user of present networks to the purpose user, CM can't give this time the professional bearing bed resource and the route resource of distributing this independent operation network that transmit, and can't adopt this Diff-Serv model scheme to realize the transmission of this business.Therefore, how to realize striding independent operation network to have the professional route selection that Qos guarantees be a problem demanding prompt solution.
