The present invention also provides a kind of switching device shifter based on two centers disaster tolerance in the IPTV system, comprises main central platform and is equipped with central platform, sets up main central platform and be equipped with central platform in the IPTV system, and carry out the strange land and dispose;
Also comprise switching server, described switching server is monitored in real time to the running status of described main central platform;
When switching server monitors main central platform running status when unusual, send initiation of services message to each network element device that is equipped with central platform;
Each network element device that is equipped with central platform responds described initiation of services message, starts business process, so that the described alternative described main central platform of central platform that is equipped with provides service for the user.
It is specially, and as shown in Figure 2, disposes two two central platforms that professional ability is identical in the IPTV system, main central platform and be equipped with central platform, and carry out the strange land and dispose.Comprise equipment in each central platform: access server, Service Database (DB), service processor (SCP), Centroid, content valut, WEB server and IMP (interface message processor (IMP)).
Being equipped with central platform when initial does not provide service to the user, has only main central platform to provide service to the user, is equipped with the Service Database of central platform and the Service Database of main central platform and keeps data sync; Be equipped with central platform and share the edge EPG and the fringe node of main central platform; The syndeton block diagram of wherein main Centroid and fringe node as shown in Figure 3, and main Centroid be equipped with Centroid and be in connection status always.
Detect the whether normally operation of main central platform equipment at the switching server that is equipped with on the central platform by the heartbeat mode; When arbitrary equipment in main central platform DB (Service Database), SCP (service processor), the Centroid network element device can not provide service, be judged as central machine room and occur unusually, need carry out two centers and switch; Switching server carries out pair process of centers switching, as shown in Figure 4,
Step S41), be equipped with the central platform device start: be equipped with the startup of central platform appliance services, timed task startup; Wherein, the switching server notice is equipped with central platform equipment I MP, WEB server, service processor, access server, DB, IMP, the unlatching of DTS server.
Step S42), main central platform equipment stops: main central platform appliance services stops, timed task stops, and the switching server that is equipped with on the central platform notifies main central platform IMP, WEB server, service processor, DTS, DB to stop service; Because disaster tolerance might equipment component be available when taking place, continuing to use to influence the service that is equipped with central platform.
Step S43), be equipped with the link re-establishment of central platform access server: switching server sends link setup message to the access server that is equipped with central platform, be equipped with the access server of central platform and be equipped with central platform service processor SCP link setup, and write the configuration information that needs;
Step S44), be equipped with central platform valut server and open service;
Step S45), main central platform edge EPG link re-establishment; Switching server sends link re-establishment message to the edge EPG of main central platform, the edge EPG of main central platform again be equipped with the central platform link setup;
Step S46), main central platform fringe node link re-establishment; Switching server sends link re-establishment message to the fringe node of main central platform, the fringe node of main central platform again be equipped with the central platform link setup;
By above step, be equipped with central platform and formally use, central apparatus provided service by being equipped with central platform when the user served.
After disaster takes place, removed the disaster of main central platform by artificial mode, on the main central platform all network element devices all normal after, need manual triggering the back to cut flow process by switching server, switching main central platform provides service for the user.Its concrete steps are as shown in Figure 5:
Step S51), main Centroid content recovery; Be equipped with Centroid be provided with main Centroid in hold the task of pushing away, when guaranteeing back to cut, the integrality of main Centroid content.Content recovery is real-time, guaranteed ageing when time cutting.
Step S52), main central platform valut content recovery;
Recovering the preparatory stage by enabling main central platform DTS client, and be equipped with central platform DTS and carry out synchronous method and recover.
Step S53), being equipped with the central platform business freezes; Notice is equipped with central platform service processor, requests such as refusing user's order; Prevent to produce in the switching flow the inconsistent phenomenon of data;
Step S54), main central platform appliance services startup, timed task start;
Step S55), be equipped with that the central platform appliance services stops, timed task stops;
Step S56), active and standby central platform valut DTS state switches;
Step S57), active and standby central platform access server link re-establishment;
Step S58), main central platform edge EPG equipment again with main central platform link setup;
Step S59), cancel main central platform business and freeze, when recovering owing to main central platform, the professional frozen state of central platform is returned and is switched to main central platform fully, and the business that needs to cancel main central platform is freezed, and opens main central platform and provides service to the user.
Through above nine steps, main central platform formally provides service for the user.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
