Description
Technical field
The present invention relates to network communications technology field, relate in particular to the management method of resource consistency between a kind of telecommunication apparatus.
Background technology
Along with the development of Internet (the Internet) technology, and the quick growth of user's request, various multi-media network services are fallen over each other to emerge in large numbers.The multimedia service that occurs in the network a large amount of bandwidth resources in the network that will account for.Therefore, when sudden high FTP (file transfer protocol (FTP)) being arranged on the network or contain the business such as HTTP (HTML (Hypertext Markup Language)) of image file, the real time business comparatively responsive to characteristics such as network transfer delay, delay jitters will be subjected to very big influence; And then the key business that causes needing in the network to guarantee is difficult to be transmitted reliably.For this reason, various QoS technology are arisen at the historic moment.For satisfying the demand of QoS, IETF has advised a lot of service models and mechanism.
The industry more application is to use integrated service model (Int-Serv) at the access and the edge of network at present, uses differentiated service model (Diff-serv) at server.Because differentiated service model (Diff-serv) is only set priority level and ensured the QoS measure, therefore, corresponding QoS ensures that effect is difficult to prediction.For this reason, industry begins to introduce an independently bearer control layer for backbone network differentiated service Diff-Serv, set up the special Diff-Serv qos signaling mechanism of a cover, just set up a resource management layer specially for Differentiated Services Diff-Serv network, the topological resource of supervising the network, being called for this resource management Differentiated Services Diff-Serv mode has the Diff-Serv of independent bearing control layer model.
In the Differentiated Services of bearer control layer (Diff-Serv) model is arranged independently, load network resource manager has disposed rule and network topology in { comprising bandwidth broker device (Bandwidth Broker) or QoS server/explorer }, is used to client's service bandwidth application Resources allocation.As shown in Figure 1, 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 be the routing information of professional application distribution, or the like.Normally each CN (nucleus equipment) that goes up to bearer network at CM (load network resource manager) simulates a routing table, and pathfinding in the territory of each CM realizes professional route in the realization bearer control layer.Resource request of each concrete type of service (being concrete Business Stream) and a series of LSP (label switched path) binding promptly utilize the resource of corresponding LSP to be, when calling is finished, LSP and other resource are discharged again.
Concrete processing procedure is: 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.Bearer network utilizes MPLS (multiprotocol label switching) technology usually, use the resource reservation mode to set up LSP, use the demonstration routing mechanism of RSVP-TE (RSVP-traffic engineering) or CR-LDP (limited tag distribution protocol) to set up LSP end to end along the service flow path of bearer control layer appointment.
Usually, after professional connection was set up successfully, the CM of the CA of service layer, bearer network key-course and the CN equipment of bearer network can be preserved the professional resource state information that takies that is connected in IP Telecommunication Network.Because abnormal factors, for example system busy or communication are subjected to the unusual reason of disturbing or the like and may cause occurring between described CA (Call Agent), CM, the CN the inconsistent situation of system resource, for example, owing to cause unusually to keep the resource status that this business connects on some equipment, and some equipment have been deleted corresponding resource state information.In IP Telecommunication Network,, then may cause the system resource of telecommunication apparatus forever to be taken the phenomenon appearance if the same professional resource occupation state that connects of equipment room is inconsistent.
At the problems referred to above, the present system resource that does not also have a kind of reliable resource consistency checking mechanism to go out and discharge the resource status that professional connection takies between CA, CM and the CN inconsistent (connection has not had application value to corresponding business) with real-time searching.

Equally, on described Requested Party telecommunication apparatus, when the message timer expiry, also need to send KA message to requesting party's telecommunication apparatus, and etc. Requested Party return response message;
Step 26: receive the response message that the other side returns when requesting party and Requested Party, when perhaps receiving the KA message that the other side sends, then with the keep-alive timer, i.e. KA timer restart.
When both sides' resource consistence, then between both sides with circulation execution in step 23 to step 26.
For the inconsistent situation of resource occurring, then as shown in Figure 3, specifically comprise:
Step 31: when Requested Party is not received described KA message in KA timer timing length, KA timer expiry then, can determine that this business connection disconnects this moment, or it is unavailable, be that the inconsistent situation of resource appears in two ends communication equipment both sides, and execution in step 32, remove this business and connect, discharge this business and connect the resource that takies;
Step 33: after Requested Party is received the KA message that the requesting party sends, confirm not have described KA message, then abandon corresponding message, and need not to return KA message to the requesting party;
Equally, if in the timing length of KA timer, do not receive the KA message of Requested Party, the then operation of execution in step 32 the requesting party.
Among the present invention, the transmission of can packing of described KA message as long as be no more than a MTU (MTU), still, then gone up independently the processing of KA message and to be finished.
In above-mentioned normal process, employing be the processing mode of point-to-point, two equipment rooms carry out the resource inspection to each connection, for each KA message, all need to respond.If the processing mode to above-mentioned point-to-point is improved, then the resource consistency that can connect the business that comprises plural telecommunication apparatus is checked.
Concrete implementation as shown in Figure 4 and Figure 5, Fig. 4 is not for the processing procedure that resource consistency is checked between the more than two devices under the inconsistent situation of resource occurring, Fig. 5 is the processing procedure that resource consistency is checked between the more than two devices that occurs under the inconsistent situation of resource, will describe the processing procedure under two kinds of situations respectively below.
With reference to Fig. 4 and shown in Figure 5, described resource consistency checks that processing procedure comprises:
Equally, when telecommunication apparatus sends resource bid message, carry KA timer timing length in the described message, after described telecommunication apparatus sends stream successful response message of mapping or resource bid success message, start described KA timer;
When being a plurality of telecommunication apparatus, as the CM1 among the figure, CM2, CN, CA1 etc., then each telecommunication apparatus all needs to start the KA timer, simultaneously, on the telecommunication apparatus that sends resource bid message at first, also needs to start the 1/3K timer, on the CA1 among the figure;
After described CA1 receives the resource bid response, when the 1/3KA timer expiry, promptly every time, just send one and be used to connect the KA message that refreshes through 1/3KA timer timing length;
When CM1, CM2, CN receive described KA message:
If there is this connection, and consistent with the opposite end connection resource, then continue to transmit this KA message downstream, if inconsistent, then remove local the connection, and send resource release message with the opposite end connection resource;
If do not have this connection, then abandon this KA message;
For the telecommunication apparatus of centre,, do not need to return KA message after receiving described KA message as CM1 and CM2; After receiving KA message for the end points telecommunication apparatus that connects,, then need the KA message of receiving is responded, promptly return KA message as the CN among Fig. 4 and Fig. 5;
If the some professional KA timer expiry that connects on some telecommunication apparatus thinks equally that then this connection disconnects, need remove this connection in this locality, and send resource release message to other telecommunication apparatus that should connect process.
