Description
Technical field
The present invention relates to the network communications technology field, be specifically related to a kind of implementation method of service quality.
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.Sudden high FTP or the business such as HTTP that contain image file take massive band width to influence, the multimedia service of real time business and make the key business in the network be difficult to obtain problems such as reliable transmission on the network, and various QoS (service quality) technology is arisen at the historic moment.
IETF (the Internet engineering duty group) has advised that a lot of service models and mechanism are to satisfy the demand of QoS.What industry was relatively approved at present is to use Int-Serv (integrated service) model in access network and edge network, uses Diff-serv (Differentiated Services) model in core network.
Differentiated service ensures QoS by the priority level measure, this model has the high characteristics of line efficiency, for avoiding the concrete effect of differentiated service to be difficult to problems such as prediction, industry has been introduced independently bearer control layer for the backbone network differentiated service, and in bearer control layer, being provided with load network resource manager, its concrete network model is shown in accompanying drawing 1, accompanying drawing 2.
Among Fig. 1, Fig. 2, dispose rule and network topology among the CM of each management domain (load network resource manager), service bandwidth application Resources allocation for the user, determine the path of customer service, and the edge router that black circles is represented among notice edge router such as Fig. 1, transmit Business Stream according to the path of appointment.Transmit customer service bandwidth application request and resource allocation result by signaling between the bearer network Control Server of each management domain, and load network resource manager is the routing information of professional application distribution etc.
Mainly carry out information interaction between CM and service control layer and other CM, mainly carry out information interaction between CM and the ER (edge router) by the COPS+ protocol interface by RCIP (Resource Connection Initial Protocol) protocol interface.Because it is not extensive that above-mentioned agreement is used at present, realizes information interaction if desired between each signalling point, need increase different agreements, implementation procedure complexity in signalling point.
Independently also can realize Internet resources and Topology Management in the bearer control layer by BB (Bandwidth Broker bandwidth broker device) is set, on the QBone try net as IETF and some manufacturers, the common promotion of research institution, be exactly that the utilized bandwidth proxy server is realized Internet resources and Topology Management.Be provided with the bandwidth broker device bearer control layer concrete network model as shown in Figure 3.
In Fig. 3, the bandwidth broker device mainly is responsible for handling from subscriber's main station, perhaps service server, perhaps network maintenance staff's bandwidth application request, the bandwidth broker device determines whether to allow user's bandwidth application according to the resource reservation situation of current network and configured strategy and the professional SLA (service level agreement) that signs with the user.
Realize the request of resource by direct transmission SIBBS between the bandwidth broker device, but do not have source synchronous mechanism between the bandwidth broker device, do not have the foundation and the maintenance process of session, also be not used in the information interaction mechanism of maintenance management.
The bandwidth broker device comes down to a load network resource manager with bandwidth broker function.Because also there are a lot of implementation issues in bandwidth broker device model, does not also have commercialization before this type order.

Embodiment
Core of the present invention is: determine the common agreement of supporting between service quality signal point, each service quality signal point carries out service quality signalling interaction according to the agreement of described common support.
Based on core concept of the present invention technical scheme provided by the invention is further described below.
The present invention at first needs to determine the common agreement of supporting between each service quality signal point, because SIP (session initiation protocol) uses one of agreement very widely at present, a lot of equipment are all supported SIP, so, SIP is carried out the agreement of service quality signalling interaction as each service quality signal point, avoided in the equipment of existing each service quality signal point, increasing the process of new agreement, made service quality implementation method of the present invention have the advantage that is easy to realize.
The present invention can expand the content of SIP as required, to satisfy the signaling requirement between each service quality signal point.Owing to only need do a spot of extension process to SIP, can finish service quality function, make service quality implementation method of the present invention have the retrofit work amount little, be easy to advantage such as realization.
Extension process to SIP can be the expansion to qos parameter, as increasing delay parameter, jitter parameter etc., also can be the expansion of resource path information, as increasing LSP (label switched path) information etc.
Among the present invention between each service quality signal point the common agreement of supporting can also be DIAMETER agreement, agreement etc. H.248.
Service quality signal point of the present invention can for: CA, load network resource manager, ER etc., wherein: load network resource manager can be for there being the load network resource manager of bandwidth broker function.
Between CA and the CM, between the CM, carry out the mutual flow process of quality of service information between CM and the ER as shown in Figure 4.
Between CA and the CM, between the CM, the method that realizes service quality function alternately by quality of service information between CM and the ER as shown in Figure 5.
In Fig. 5, the service quality signal that transfers to CM from CA comprises: resource request signaling, resource release signaling, resource query signaling, resource audit signaling etc.
The service quality signal that transfers to CA from CM comprises: resource request confirms that signaling, resource request rejection signaling, resource release response signaling, resource query response signaling, resource status report signaling, resource audit signaling, overload to report signaling etc.
Mutual service quality signal between the CM comprises: resource request signaling, resource request confirm that signaling, resource request rejection signaling, resource release signaling, resource release response signaling, resource query signaling, resource query response signaling, resource status report signaling, resource audit signaling, overload to report signaling etc.
The service quality signal that transfers to ER from CM comprises: resource bid signaling, resource release signaling, resource status inquiry signaling, source synchronous demand signalling etc.
The service quality signal that transfers to CM from ER comprises: resource bid report signaling, resource discharge the report signaling, resource status reports signaling, overload to report signaling, source synchronous signaling etc.
The common agreement of supporting of each service quality signal point is not limited to Session Initiation Protocol, DIAMETER agreement, agreement H.248 among the present invention, also can adopt the agreement of the common support of other each service quality signal points to finish service quality function.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, and the claim of application documents of the present invention comprises these distortion and variation.
