Description
Technical field
The present invention relates to network communications technology field, relate in particular to the implementation method that entity of carrying control function in a kind of network issues control strategy.
Background technology
Along with the continuous increase of Internet scale, various network services are fallen over each other to emerge in large numbers, and advanced multimedia system emerges in an endless stream.Therefore, at any time have sudden high FTP (file transfer protocol (FTP)) on the network or contain the professional transmission such as HTTP (HTML (Hypertext Markup Language)) of image file, at this moment, influence probably in the network the comparatively responsive real time business of characteristics such as propagation delay time, delay jitter, even may cause corresponding real time business to be subjected to very big influence; On the other hand, multimedia service a large amount of bandwidth that accounted for like this, just is difficult to be transmitted reliably for the key business that needs in the existing network to guarantee service quality.
For this reason, various QoS (service quality) technology of assurance is arisen at the historic moment.IETF has advised 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 model (Int-Serv) at the access and the edge of network, uses differentiated service model (Diff-serv) at server.Differentiated service model (Diff-serv) ensures that the QoS measure has the high characteristics of line efficiency though only set priority level, and concrete effect is difficult to prediction.
Therefore, industry begins to introduce an independently bearer control layer for backbone network differentiated service Diff-Serv, set up the special Diff-ServQoS signaling mechanism of a cover, as in order to promote the application of Diff-Serv, on the common QBone try net that promotes of IETF and some manufacturers and research institution, utilized bandwidth proxy server (Bandwidth Broker) model is realized Internet resources and Topology Management, has some other manufacturer to propose similar QoS server/explorer technology and manages topological resource and coordinate the QoS ability in each differentiated service Diff-Serv zone.
Described method all is to set up a resource management layer specially for Differentiated Services Diff-Serv network, the topological resource of supervising the network, to obscure in order not causing, above-mentioned resource management Differentiated Services Diff-Serv model to be renamed as the network model with independent bearing control layer.
As shown in Figure 1, in the network model of bearer control layer is independently arranged, the bearer network Control Server { comprises bandwidth broker device (Bandwidth Broker) or QoS server/explorer } and has disposed rule and network topology, is client's service bandwidth application Resources allocation.The bearer network Control Server of each management domain transmits client's service bandwidth application request and result each other by signaling, and load network resource manager is the routing information of professional application distribution etc.
When the service bandwidth application of bearer control layer process user, will determine the path of customer service.Load network resource manager can notify edge router to transmit Business Stream according to the path of appointment.
How bearer network realizes that according to the definite path of bearer control layer user traffic flow is by specifying routing forwarding, the existing technology of industry mainly is to utilize the MPLS technology at present, use the resource reservation mode to set up LSP (label switched path), use the explicit route mechanism of RSVP-TE (RSVP-traffic engineering) or CR-LDP (based on the limited tag distribution protocol of route) to set up LSP end to end along the service flow path of bearer control layer appointment.
For the IP qos signaling flow process in IP QoS (Internet protocol service quality) framework end to end is provided.A lot of tissues have proposed the handling process that single phase and two stage control strategy issue, and described control strategy mainly is meant the resource control information that is handed down to router.
The control strategy mode of issuing of described single phase is meant after distributing corresponding resource information according to resource request and directly is handed down to corresponding router.
The described two stage control strategy modes of issuing are not handed down to router after being meant and distributing corresponding resource according to resource request, but corresponding event is handed down to corresponding router after triggering again by the time.
At present, on the entity of being responsible for resource allocation, on the BCFE (entity of carrying control function) among the RACS (resource access control subsystem), can't select to use single phase or two stage control strategy to issue mode neatly.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide that entity of carrying control function issues the implementation method of control strategy in a kind of network, thereby make and to select single phase or the two stage control strategy mode of issuing to carry out issuing of control strategy neatly on the BCFE in RACS.
