Fig. 3 realizes the general flow chart that is redirected for the present invention.
Embodiment
Referring to Fig. 1, Fig. 1 is the system diagram that the realization of one embodiment of the invention is redirected, this system comprises media business server (MSS, Media Service Server), media business Control Server (MSCS, Media Service Control Server), subscriber terminal equipment (UE, User Equipment), Service Database (MSDB, Media Service Database).
Wherein, MSS is used to receive the RTSP service request that UE sends as the service request control unit of node in the IPTV system; Also be used for simultaneously can't providing under the situation of service and send redirect request to MSCS at this service server; Can also return service available MSS access links to UE.
UE is used for sending the RTSP service request to MSS, according to the RTSP service response that MSS returns, initiates the RTSP service request again to available MSS.
MSCS is used for the synchronous MSS information such as resource situation that had of each MSS from MSDB, and is saved in the shared drive; Upgrade the resource situation of each MSS simultaneously by inquiry MSDB.Can also receive redirect request and the basis service available MSS of information inquiries such as the resource name chained address wherein of MSS, again the MSS chained address that inquires be returned to MSS.In addition, after business process is restarted because of reasons such as collapses,, provide disaster recovery capability to a certain degree by reading the resource information of each MSS in the shared drive.
In concrete the application, MSCS can be redirected required MSS resource information synchronously from MSDB.Usually, only need be used to finish the required minimum data set of redirection function synchronously, to reduce taking of data sync time and shared drive, that wherein must comprise is the nodal information controlled of each MSS and the ID of all resources of intranodal.And, MSCS can be regularly from the increment information of the synchronous MSS resource of MSDB, with guarantee and MSDB in data consistent.The record that every changes among the MSDB all can be assigned with time corresponding and stab.Therefore MSCS is when MSDB obtains increment information, and the record of the timestamp of a synchronized timestamp during greater than last success synchronously will need synchronous timestamp to be inserted in the existing data acquisition system according to the sequencing of timestamp afterwards.The use of timestamp has guaranteed integrality and the order that increment information is synchronous, has also just guaranteed the data consistency of shared drive and MSDB.
MSCS can create the processing of index to synchronous MSS resource data, to improve inquiry velocity.Index can not preserved in shared drive, but preserves in the heap space of process, to reduce taking of shared drive as far as possible.Here said index is meant that the ID with resource is keyword key, and the node at resource place is the Hash HASH table that value value creates, and can find the MSS information of resource place node like this by the resource ID in the redirect request fast.
Certainly, after having obtained increment information, can upgrade index equally.
When MSCS received from the redirect request of MSS, according to searching available MSS chained address in the MSS resource information of this request in shared drive, and the available MSS chained address that will find fed back to MSS.
After the MSDB collapse, MSCS can rely on the service resources information in the shared drive to continue to provide redirect services.This be because, even after business process collapse, because shared drive is not released; Therefore after business process is restarted, can read the data in the shared drive again, and rebuild described index, to continue to provide redirect services.
As seen from the above description, system shown in Figure 1 can realize flow process shown in Figure 2.Referring to Fig. 2, Fig. 2 is the flow chart that the realization of one embodiment of the invention is redirected, step 201 in this flow process is described the flow process of synchronizing traffic data and the process that business datum makes up to step 205 in shared drive, step 206 is to the handling process of step 210 description to the RTSP service request.Flow process shown in Figure 2 may further comprise the steps:
Step 201:MSCS starts the back and creates shared drive, sends data synchronization request by the data base querying interface to MSDB afterwards, needs data in synchronization to comprise VOD distributed intelligence, TVOD distributed intelligence, channel distributed intelligence.
Step 202:MSDB gives MSCS with data that MSCS asked by the data sync response feedback, and MSCS receives that the data sync of MSDB replys, and therefrom parses all data and is saved in the shared drive.
Step 203:MSCS carries out index creation to the data of preserving in the shared drive, is that the HASH index created in keyword with request type and content ID (as content ID of VOD, TVOD, channel etc.), and the HASH index is saved in this process heap memory.
Step 204:MSCS regularly sends the increment synchronization request to MSDB, comprises last increment or full dose successful timestamp synchronously in the request.
Step 205:MSDB feeds back to MSCS with data updated after the described timestamp by the increment syn ack, MSCS uses the data in incremental data (incremental data that mainly comprises VOD, TVOD, channel table) the renewal shared drive that MSDB fed back, simultaneously can also be according to the index in the Data Update heap memory after upgrading.
Step 206:UE initiates the RTSP service request to MSS A.
After step 207:MSS A receives the RTSP service request, determine that self temporarily can't provide service, then initiates internodal redirect request to MSCS.
After step 208:MSCS receives the redirect request of MSS A, by resolving service field in this request to obtain request type (VOD, TVOD, channel) and content ID, inquire about corresponding index, from shared drive, obtain address and the port information of the complete MSS B that serves.
Step 209:MSCS is packaged into the MSS chained address with MSS information such as the address of the MSS B that obtains and port informations, and this MSS chained address is carried on to be redirected feeds back to MSS A in replying.
After step 210:MSS A receives redirected the replying of MSCS, the MSS chained address that is wherein comprised is carried in the RTSP service response sends to UE.
Step 211:UE receives the RTSP service response from MSS A, and the pairing MSS B in the MSS chained address in this RTSP service response initiates the RTSP service request.
In conjunction with above-described system and method as can be known, the present invention realizes that the operation thinking that is redirected can represent as shown in Figure 3.Referring to Fig. 3, Fig. 3 realizes the general flow chart that is redirected for the present invention, and this flow process may further comprise the steps:
Step 310: in the MSS information synchronization of the MSDB shared drive beyond the MSDB.
When step 320:UE need be redirected, determine available MSS according to the MSS information in the shared drive, and notice UE.
Step 330:UE is redirected at notified available MSS.
Need to prove, in system shown in Figure 1, lock unit can be set among the MSCS, be redirected decision package.Wherein, lock unit can be with in the MSS information synchronization of the MSDB shared drive beyond the MSDB; In fact, lock unit can safeguard the shared drive among the MSCS, and with synchronous MSS information storage in this shared drive.When receiving that information such as redirect request determine that UE need be redirected, redirected decision package can be determined available MSS according to the MSS information in the described shared drive, and feeds back the chained address of this available MSS to UE.
Particularly, lock unit can send data synchronization request to MSDB when synchronous described MSS information, trigger the data that MSDB is asked according to this data synchronization request feedback; And MSDB institute feedback data is saved in the shared drive of having created.Be redirected decision package when determining the MSS that UE can use, then can receive because of UE and need be redirected the redirect request of initiating, by resolving service field in this request obtaining request type and content ID, but from shared drive, obtain address and the port information of the MSS of complete service UE.
In addition, lock unit can be created the operation of index, and redirected decision package then can be used to the index of creating; And redirected decision package can also be notified to UE with available MSS, triggers UE and is redirected at notified available MSS.
In sum as seen, because the resource information of each MSS all remains in the shared drive, and the access speed of shared drive is far above database, so redirect request can be handled faster, and user experience is improved greatly.Under the situation that database collapses and business process is restarted owing to a variety of causes, still can rely on the data in the shared drive to continue to provide redirect services simultaneously, the reliability of system is provided greatly.
Obviously, no matter be method or system, the present invention realizes that the technology that is redirected is compared with the prior art and has following advantage:
(1), MSCS when receiving the redirect request of MSS, Query Database not, but the node resource information of preserving in the inquiry shared drive is obtained the MSS address date that can serve, inquiry velocity improves greatly;
(2) even database can't provide service, MSCS still can rely on the data in the shared drive that service is provided;
(3), under the situation that database collapse and business process are restarted, the data in the shared drive can not disappear, MSCS only needs rebuild index operation to the data in the shared drive, can continue to provide service.
The failure that above advantage all can effectively avoid the problem because of database to cause the user to ask, thereby can obviously improve user satisfaction.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
