detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides a data push method, and the data push method is applied to an IPTV cluster. Referring to FIG. 1, the IPTV cluster includes a main EPG server and a plurality of slave EPG servers. Referring to FIG. 2, in the data push method of the present invention. In an embodiment, the data pushing method includes:

Step S10, when receiving the service request sent by the IPTV terminal, determining, by the EPG server, whether the received service data pointed by the service request is currently stored;

As is well known, the content of the ordinary WEB server is stored locally, but for the EPG server, the situation is very special, because the WEB content is very large, mainly the picture and third-party templates (such as JSP files, etc.), and With the expansion of business, 4K is extremely clear, and various value-added services are booming. This part of the content will also grow exponentially, which will cause the EPG server to be overwhelmed in content synchronization. Although WEB content is large, the content that is actually accessed in each EPG server in the live network environment is a very small part. Therefore, it is a great waste of I/O resources to place all WEB content locally on the EPG server. , affect the performance of the IPTV cluster.

Based on the foregoing deficiencies, the main purpose of this embodiment is to separate the WEB content of the EPG server. To this end, the present embodiment provides a distributed IPTV cluster architecture as shown in FIG. 1 , as shown in FIG. 1 , compared with related technologies. This embodiment introduces two types of WEB containers, namely, a primary EPG server and a secondary EPG server, wherein all WEB content is placed on the primary EPG server, and the primary EPG server is responsible for distributing the user's WEB request for load balancing; the secondary EPG server Responsible for intercepting and processing the user's WEB request, the slave EPG server downloads the corresponding WEB content from the main EPG server to the local WEB container when processing the user's WEB request. Those skilled in the art can understand that the on-demand downloading method from the EPG server can ensure that only a small amount of content is contained in the WEB container local to the EPG server, and there is no need to care about the synchronization of the WEB content, and the WEB downloaded to the WEB container. The content is reusable and does not need to be downloaded again if it already exists locally. In addition, the primary EPG server can automatically sense the working status of the EPG server in the cluster (such as monitoring through heartbeat packets). When a certain EPG server is abnormal, the primary EPG server can remove the EPG server from the cluster. The request is no longer distributed from the EPG server. When the station returns from the EPG server status, the main EPG server can add it to the cluster to provide services. In addition, the primary EPG server can automatically sense the newly added slave EPG server, which enables the cluster to be smoothly expanded without reconfiguration or restart, to meet higher and higher performance requirements. It should be noted that the users of the IPTV cluster That is, the IPTV terminal, the IPTV terminal may include at least one of a mobile terminal such as a computer, a set top box, a smart TV, or a smart phone.

In this embodiment, when the primary EPG server allocates the EPG server that provides the service to the IPTV terminal, the IP_Hash algorithm is used to combine the load status of each EPG server to perform weighting, and the slave IPTV terminal is allocated a lightly loaded slave EPG server in real time. Specifically, the primary EPG server virtualizes each EPG server in the cluster into n nodes and evenly distributes them on the hash ring; and when receiving the original service request sent by the IPTV terminal, calculates a hash value according to the configured parameters. Finding the virtual node in the vicinity of the calculated hash value on the hash ring, and then weighting according to the load state of the nearby virtual node to determine the virtual node with light load, and the slave EPG server corresponding to the lighter virtual node The information is sent to the IPTV terminal, and the IPTV terminal is served by the EPG server corresponding to the virtual node. It should be noted that, after receiving the slave EPG server information sent by the primary EPG server, the IPTV terminal repackages the original service request into a new service request and sends the message to the slave EPG server, and the subsequent other services. Requests are also sent to the assigned slave EPG server.

When receiving the service request sent by the IPTV terminal based on the information from the EPG server, the slave EPG server determines whether the service data (ie, WEB content) pointed to by the received service request is currently stored, according to the judgment result. The corresponding operation is performed, for example, when the service data pointed by the service request is stored, the stored service data pointed by the service request may be directly sent to the IPTV terminal.

Step S20: When the service data pointed by the service request is not currently stored, the slave EPG server acquires and stores the service data pointed by the service request based on the primary EPG server, and redirects the service request to The primary EPG server, for the primary EPG server to push the service data pointed to by the received service request to the IPTV terminal;

In this embodiment, when the service data pointed by the service request is not currently stored, the EPG server adds the service data pointed by the service request to the download queue, and the service that the service request points to by the download queue Data is downloaded from the primary EPG server to the local. And adding, by the EPG server, the service data pointed by the service request to the download queue, and redirecting the received service request to the primary EPG server, where the primary EPG server pushes and receives the received data to the IPTV terminal. The business data pointed to by the service request. It can be understood by those skilled in the art that, in this embodiment, the slave EPG server and the IPTV terminal can simultaneously obtain the service data pointed by the service request, and the IPTV terminal can obtain the acquired service data. Presented to the user. In addition, when the service data pointed by the service request is requested again, the service data pointed by the service request can be directly obtained from the local.

In step S30, when the service data pointed by the service request is currently stored, the EPG server sends the stored service data pointed by the service request to the IPTV terminal.

Based on the foregoing description, those skilled in the art can understand that the purpose of storing the service data from the EPG server is to directly provide the service with the stored service data when receiving the service request for the stored service data again. Therefore, in this embodiment, when the service data pointed by the service request is currently stored, The service data pointed to by the stored service request is directly sent from the EPG server to the IPTV terminal, and the IPTV terminal presents the service data pointed by the service request to the user.

In addition, because the primary EPG server plays the role of “heads” in the IPTV cluster, if the primary EPG server works abnormally, the entire IPTV cluster will not be able to provide external services normally. Therefore, in order to improve the stability of the IPTV cluster, the embodiment also introduces a redundancy mechanism. Specifically, as shown in FIG. 1 , the IPTV cluster proposed in this embodiment further includes a backup EPG server, which is used as a hot backup of the primary EPG server. For example, when the primary EPG server is abnormal, the primary EPG server and the standby EPG server are switched, and the standby EPG server takes over the primary EPG server.

Further, in this embodiment, the primary EPG server also periodically synchronizes the local WEB content. As shown in FIG. 1 , the IPTV cluster proposed in this embodiment further includes an FTP server, and the primary EPG server is based on the FTP. The server performs synchronization of the local WEB content. For example, the main EPG server acquires a new picture file from the FTP server and stores it locally. It should be noted that after the synchronization is completed, the primary EPG server also sends a content synchronization notification to each slave EPG server in the cluster, and notifies each slave EPG server to perform content synchronization with the primary EPG server; After the content synchronization notification sent by the primary EPG server, the locally stored WEB content is verified to update, add, and/or delete the local WEB content.

The data pushing method proposed in this embodiment separates the full amount of WEB content (service data) into each slave EPG server in the IPTV cluster including the primary EPG server and the slave EPG server, and each slave EPG server is based on the stored WEB content and receiving. The IPTV terminal's service request provides services and updates the stored WEB content as needed. Compared with the related art, the embodiment of the present invention avoids the waste of IPTV cluster I/O resources caused by synchronizing the full amount of WEB content, and can achieve the purpose of improving the working performance of the IPTV cluster.

Further, based on the foregoing first embodiment, a second embodiment of the data pushing method in the embodiment of the present invention is provided. In this embodiment, the service data includes a first type of service data and a second type of service data. Before the redirecting the service request to the primary EPG server in the step S20, the method may further include:

When the service data pointed to by the service request is the second type of service data, and based on the service data pointed to by the service request by the primary EPG server,

The service data acquired from the EPG server is loaded into the servlet container of the EPG server, and the result of the operation is returned to the IPTV terminal as the service data pointed by the service request.

It should be noted that resources can be referenced as static or dynamic resources, which is used by The StaticResource tag extension or the DynamicResource tag extension is done. The static resource refers to a resource that can be directly fed back to the user when requested by the user; the dynamic resource refers to when the user requests, the dynamic resource is run according to different users to feed back different results. In this embodiment, when receiving the service request of the IPTV terminal, it is also required to determine the operation to be performed according to the StaticResource mark extension or the DynamicResource mark extension carried in the received service request.

Specifically, when the service data pointed by the service request is not currently stored, and the service request carries the StaticResource mark extension, the IPTV terminal requests the static resource that is not currently stored (the first type of service data). The service data pointed to by the service request is added to the download queue from the EPG server, and the service data pointed by the service request is downloaded from the primary EPG server to the local by the download queue. . And adding, by the EPG server, the service data pointed by the service request to the download queue, and redirecting the received service request to the primary EPG server, where the primary EPG server pushes and receives the received data to the IPTV terminal. The business data pointed to by the service request.

When the service data pointed to by the service request is not currently stored, and the service request carries the DynamicResource tag extension, the IPTV terminal requests that the dynamic resource that is not currently stored (the second type of service data) needs to be consumed. The processing resource is running. At this time, the service data pointed by the service request is added to the download queue from the EPG server, and the service data pointed by the service request is downloaded from the main EPG server to the local by the download queue. After downloading the service data pointed by the service request from the primary EPG server to the local area, the slave EPG server loads the downloaded service data into the servlet container of the EPG server, and uses the running result as The service data pointed to by the service request is returned to the IPTV terminal to avoid unnecessary occupation of the processing resources of the primary EPG server, thereby improving the working performance of the IPTV cluster.

When the service data pointed by the service request is currently stored, and the service request carries the StaticResource mark extension, the IPTV terminal requests the currently stored static resource (the first type of service data), and does not need to be processed. The resource operation directly sends the stored service data pointed to by the service request to the IPTV terminal, where the IPTV terminal presents the service data pointed by the service request to the user.

When the service data pointed to by the service request is currently stored, and the service request carries the DynamicResource tag extension, the IPTV terminal requests the currently stored dynamic resource (the first type of service data), and needs to consume the processing resource. Running, at this time, the EPG server loads the stored service data pointed by the service request into the Servlet container of the EPG server, and returns the running result as the service data pointed by the service request to the office. Said IPTV terminal.

Further, in this embodiment, when the content is synchronized with the FTP server, the main EPG server needs to pre-compile the acquired dynamic resources and obtain the pre-compilation when acquiring the dynamic resources from the FTP server. Compiling the object, for example, after the main EPG server obtains the JSP file from the FTP server, pre-compiling the obtained JSP file into a class file storage for the slave EPG server when needed Get and load the run.

Further, based on the foregoing first embodiment, a third embodiment of the data pushing method of the present invention is proposed. In this embodiment, before the step S30, the method may further include:

When the verification is passed, the step S30 is performed;

As is well known, in the network transmission process, there are problems such as data packet loss and data packet disorder. Therefore, in the embodiment, when the content separation is performed, the service data separated from the EPG server may be related to the primary EPG server. The stored original service data is different. To ensure that the user can be served normally, the slave EPG server needs to perform verification operations on the service data before providing the service.

Specifically, when the service data pointed by the service request is currently stored, the EPG server performs a verification operation on the service data pointed by the stored service request, for example, the CRC check (Cyclic Redundancy Check) is used in this embodiment. , Cyclic Redundancy Check) verifies the integrity of the stored service data pointed to by the service request. The service data pointed to by the stored service request is directly sent from the EPG server to the IPTV terminal, where the service is sent by the IPTV terminal, when the stored service data pointed to by the service request is verified. The service data pointed to by the request is presented to the user; when the stored service data verification pointed by the service request fails, the EPG server adds the service data pointed by the service request to the download queue, and the service is sent by the download queue. The service data pointed to by the request is downloaded from the main EPG server to the locality, and replaces the service data pointed to by the locally stored service request. And adding, by the EPG server, the service data pointed by the service request to the download queue, and redirecting the received service request to the primary EPG server, where the primary EPG server pushes and receives the received data to the IPTV terminal. The business data pointed to by the service request.

Further, based on any of the foregoing embodiments, a fourth embodiment of the data pushing method of the embodiment of the present invention is provided. In this embodiment, before the step S10, the method may further include:

Verifying, by the EPG server, the validity of the obtained session data;

When the verification is passed, the step S10 is performed.

It should be noted that, based on the first embodiment, this embodiment further provides a distributed session. The solution to improve the scalability of the IPTV cluster. Specifically, the primary EPG server records metadata information of the maintenance session, including version information, session location, copy information, and recovery, re-allocation, and invalidation of time-out session information when exiting from the EPG server; The slave EPG server is configured to obtain, from the primary EPG server, session information of the IPTV terminal when there is a service request of the new IPTV terminal, if the location information of the session is taken out from the corresponding slave EPG server (including the The session data of the IPTV terminal is read from the EPG server or the other, and if not, the main EPG server is notified to update the session information after newly creating the session object. For example, when receiving a service request from the EPG server A to the IPTV terminal, a session object is created. If the IPTV terminal is assigned to the slave EPG server B next time, the EPG server B can acquire the session created from the APG server A node according to the session ID. Object. Optionally, the embodiment uses the user ID corresponding to the IPTV terminal (assigned when the user registers) as the session ID, so that the sessionID does not need to be delivered from the EPG server.

In addition, in order to prevent the data from being damaged or the session is lost due to the failure of the EPG server, the embodiment also provides a session copy function, that is, the session data is stored in multiple copies. Specifically, after the session object is created persistently, the data is simultaneously copied from the EPG server to other slave EPG servers. Alternatively, the number of copies is set to an odd number, for example, the number of copies is set to three in this embodiment. When the local session data is in error, the EPG server can recover the erroneous data by copying the complete copy, so that the copy of the data is restored to the expected set number to ensure high reliability of the data.

In this embodiment, when receiving the service request sent by the IPTV terminal based on the information from the EPG server, the stored session data of the IPTV terminal is obtained from the EPG server. After obtaining the session data of the IPTV terminal, the validating the validity of the obtained session data from the EPG server, wherein verifying the validity of the obtained session data comprises: verifying the session Whether the data is complete, verify whether the session data is in error, etc. When the verification is passed, the EPG server determines whether the service data pointed by the received service request is currently stored to determine how to provide the service for the IPTV terminal. For details, refer to the foregoing embodiment, and details are not described herein again.

Further, in this embodiment, when the session data is not acquired, the sending an acquisition request from the EPG server to the primary EPG server;

Based on the foregoing description, those skilled in the art can understand that when the session data is corrupted or the session data is created by other EPG servers, the slave EPG server cannot obtain the session data of the corresponding IPTV terminal locally. In this embodiment, when the session data is not obtained, the EPG server sends an acquisition request to the primary EPG server, so that the primary EPG server can provide information according to the received acquisition request and the stored session metadata information. The session location information (instruction information) of the corresponding session data is fed back from the EPG server. Upon receiving the session location information returned by the primary EPG server according to the acquisition request, the slave EPG server obtains from the EPG server corresponding to the session location information. Take the session data. After the session data is obtained, the foregoing data pushing process is started. For details, refer to the foregoing embodiment, and details are not described herein again.

Further, since the primary EPG server also performs a failure process on the timeout session, when the slave EPG server sends an acquisition request to the primary EPG server to request session data, the primary EPG server may have timed out due to the corresponding session data. No indication is returned. In this embodiment, the slave EPG server creates the session data of the IPTV terminal when the indication information returned by the primary EPG server is not received, and notifies the primary EPG server to update the session metadata information after the completion of the creation. Reference may be made to the foregoing description, and details are not described herein again.

The embodiment of the present invention further provides a data pushing device, where the data pushing device is applied to an IPTV cluster. Referring to FIG. 1, the IPTV cluster includes a primary EPG server and a plurality of secondary EPG servers. Referring to FIG. 3, in the embodiment of the present invention, In a first embodiment of the data pushing device, the data pushing device comprises:

Those skilled in the art can understand that the on-demand downloading method from the EPG server can ensure that only a small amount of content is contained in the WEB container local to the EPG server, and there is no need to care about the synchronization of the WEB content, and the WEB downloaded to the WEB container. The content is reusable and does not need to be downloaded again if it already exists locally. In addition, the primary EPG server can automatically sense the working status of the EPG server in the cluster (such as monitoring through heartbeat packets). When a certain EPG server is abnormal, the primary EPG server can remove the EPG server from the cluster. The request is no longer distributed from the EPG server. When the station returns from the EPG server status, the main EPG server can add it to the cluster to provide services. In addition, the primary EPG server can automatically sense the newly added slave EPG server, which can make the cluster not reconfigured. Smoothly expand or restart, and respond to higher and higher performance requirements. It should be noted that the IPTV terminal is an IPTV terminal, and the IPTV terminal may include at least one of a mobile terminal such as a computer, a set top box, a smart TV, or a smart phone.

The first determining module 10, when the EPG server receives the service request sent by the IPTV terminal based on the information from the EPG server, determines whether the service request from the EPG server is currently stored and received. The service data (ie, the WEB content) is configured to perform a corresponding operation according to the judgment result. For example, when the service data pointed by the service request is stored, the stored service data pointed by the service request may be directly sent to the IPTV terminal.

Compared with the related art, the embodiment of the present invention avoids the waste of IPTV cluster I/O resources caused by synchronizing the full amount of WEB content, and can achieve the purpose of improving the working performance of the IPTV cluster.

Further, based on the first embodiment of the foregoing apparatus, a second embodiment of the data pushing apparatus of the embodiment of the present invention is provided. In this embodiment, the service data includes a first type of service data and a second type of service data. The data pushing device further includes a second determining module, configured to determine whether the service data pointed by the service request is the first type of service data;

The processing module 20 is further configured to redirect the service request to the primary EPG server when the service data pointed by the service request is the first type of service data;

The sending module 30 is further configured to: when the service data pointed to by the service request is the second type of service data, and the processing module 20 obtains the service data pointed by the service request by the primary EPG server, The business data is loaded into the servlet container it is running from the EPG server and will run the result The service data pointed to by the service request is returned to the IPTV terminal.

It should be noted that resources can be referenced as static resources or dynamic resources, which is done by using the StaticResource markup extension or the DynamicResource markup extension. The static resource refers to a resource that can be directly fed back to the user when requested by the user; the dynamic resource refers to when the user requests, the dynamic resource is run according to different users to feed back different results. In this embodiment, when receiving the service request of the IPTV terminal, it is also required to determine the operation to be performed according to the StaticResource mark extension or the DynamicResource mark extension carried in the received service request.

Specifically, when the service data pointed by the service request is not currently stored in the EPG server, and the service request carries the StaticResource mark extension, the IPTV terminal requests that the EPG server is not currently stored. The static resource (the first type of service data) does not need to consume the processing resource to run. At this time, the processing module 20 adds the service data pointed by the service request to the download queue of the EPG server, and the download queue The service data pointed to by the service request is downloaded from the primary EPG server to the local EPG server where it is located. While the service data pointed to by the service request is added to the EPG server download queue, the processing module 20 redirects the received service request to the primary EPG server, and the primary EPG server The IPTV terminal pushes the received service data pointed by the service request.

When the service data pointed to by the service request is not currently stored in the EPG server, and the service request carries the DynamicResource mark extension, the IPTV terminal requests that the dynamic resource that is not currently stored by the EPG server is requested. The second type of service data needs to consume the processing resource. At this time, the processing module 20 adds the service data pointed by the service request to the download queue of the slave EPG server, and the service queue points the download request by the download queue. The business data is downloaded from the primary EPG server to where it is located from the EPG server. After downloading the service data pointed by the service request from the primary EPG server to the local location of the slave EPG server, the sending module 30 loads the downloaded service data into the servlet container of the slave EPG server, and Returning the result of the operation as the service data pointed by the service request to the IPTV terminal, so as to avoid unnecessary occupation of the processing resources of the primary EPG server, thereby improving the working performance of the IPTV cluster.

When the service data pointed by the service request is currently stored in the EPG server, and the service request carries the StaticResource tag extension, the IPTV terminal requests that the static resource currently stored by the EPG server is located. a type of service data, which does not need to consume the processing resource, and the sending module 30 directly sends the service data pointed to by the service request stored by the EPG server to the IPTV terminal, where the IPTV terminal will The business data pointed to by the business request is presented to the user.

When the service data pointed by the service request is currently stored in the EPG server, and the service request carries the DynamicResource tag extension, the IPTV terminal requests that the dynamic resource currently stored by the EPG server is located. a type of service data, which needs to consume processing resources, and the sending module 30 loads the service data pointed to by the service request stored by the EPG server to the Running from the servlet container of the EPG server, and returning the result of the operation as the service data pointed to by the service request to the IPTV terminal.

Further, in this embodiment, when the content is synchronized with the FTP server, the main EPG server needs to pre-compile the acquired dynamic resources and obtain the pre-compilation when acquiring the dynamic resources from the FTP server. Compiling the object, for example, after obtaining the JSP file from the FTP server, the main EPG server pre-compiles the obtained JSP file into a class file storage for the slave EPG server to acquire and load and run when needed.

Further, based on the first embodiment of the foregoing apparatus, a third embodiment of the data pushing apparatus according to the embodiment of the present invention is provided. In this embodiment, the sending module 30 is further configured to be currently stored when the EPG server is located from the EPG server. And when the service data pointed to by the service request is performed, performing verification operation on the stored service data pointed by the service request; and transmitting, when the verification is passed, the stored service data pointed by the service request to the IPTV terminal;

The data pushing device further includes an updating module, configured to update the stored service data pointed by the service request based on the primary EPG server when the verification fails, and redirect the service request to the primary EPG server.

As is well known, in the network transmission process, there are problems such as data packet loss and data packet disorder. Therefore, in the embodiment, when the content separation is performed, the service data separated from the EPG server may be related to the primary EPG server. The original business data stored is different. In order to ensure that the service can be provided to the user normally, the business data needs to be verified before the service is provided.

Specifically, when the EPG server currently stores the service data pointed by the service request, the sending module 30 performs a verification operation on the service data that the service request is stored from the EPG server, for example, In the embodiment, the sending module 30 uses a CRC check (Cyclic Redundancy Check) to verify the integrity of the stored service data pointed to by the service request. The sending module 30 directly sends the service data pointed to by the service request stored by the EPG server to the IPTV terminal, where the IPTV is directly transmitted by the stored service data. The terminal presents the service data pointed by the service request to the user; when the stored service data verification pointed by the service request fails, the update module adds the service data pointed by the service request to the download queue of the EPG server Downloading, by the download queue, the service data pointed by the service request from the primary EPG server to the local EPG server, and after completing the download, the update module stores the service locally stored by the EPG server. The service data pointed to by the request is replaced with the service data pointed to by the service request newly downloaded by the download queue. The update module redirects the received service request to the primary EPG server by adding the service data pointed by the service request to the download queue of the slave EPG server, and the primary EPG server is The IPTV terminal pushes the service data pointed to by the service request received.

Further, based on any of the foregoing embodiments, a fourth embodiment of the data pushing apparatus of the embodiment of the present invention is provided. In this embodiment, the data pushing apparatus may further include a session module, where Receiving the service request sent by the IPTV terminal from the EPG server, acquiring the session data of the IPTV terminal stored by the EPG server; and verifying the validity of the obtained session data;

It should be noted that, based on the first embodiment, the embodiment further provides a distributed session solution to improve the scalability of the IPTV cluster. Specifically, the primary EPG server records metadata information of the maintenance session, including version information, session location, copy information, and recovery, re-allocation, and invalidation of time-out session information when exiting from the EPG server; The slave EPG server is configured to obtain, from the primary EPG server, session information of the IPTV terminal when there is a service request of the new IPTV terminal, and if yes, retrieve the location information of the session from the corresponding slave EPG server (including The local end or other from the EPG server reads the session data of the IPTV terminal. If not, the new EPG server is notified to update the session information after the session object is newly created. For example, when receiving a service request from the EPG server A to the IPTV terminal, a session object is created. If the IPTV terminal is assigned to the slave EPG server B next time, the EPG server B can acquire the session created from the APG server A node according to the session ID. Object. Optionally, the embodiment uses the user ID corresponding to the IPTV terminal (assigned when the user registers) as the session ID, so that the sessionID does not need to be delivered from the EPG server.

In this embodiment, when the session module receives the service request sent by the IPTV terminal based on the information from the EPG server, the session module acquires session data of the IPTV terminal stored by the EPG server. After obtaining the session data of the IPTV terminal, verifying the validity of the acquired session data, where verifying the validity of the obtained session data includes: verifying whether the session data is complete, and verifying Whether the session data is in error or the like. When the verification is passed, the first judging module 10 determines whether the EPG server currently stores the service data pointed by the received service request to determine how to provide the service for the IPTV terminal. For example, it will not be described here.

Further, in this embodiment, the session module is further configured to: when the session data is not acquired, Sending an acquisition request to the primary EPG server; and, upon receiving the indication information returned by the primary EPG server according to the acquisition request, acquiring the session data from the EPG server corresponding to the indication information.

Based on the foregoing description, those skilled in the art can understand that when the session data is corrupted or the session data is created by other EPG servers, the session module will not be able to locally obtain the session data of the corresponding IPTV terminal from the EPG server. In this embodiment, when the session data is not obtained, the session module sends an acquisition request to the primary EPG server, so that the primary EPG server sends the acquisition request and the stored session metadata information to the primary EPG server. The session location information (instruction information) of the corresponding session data is fed back from the EPG server. The session module acquires the session data from the EPG server corresponding to the session location information based on the session location information returned by the primary EPG server according to the acquisition request. After the session data is obtained, the foregoing data pushing process is started, and details are not described herein again.

Further, since the primary EPG server also performs a failure process on the timed session, when the session module sends an acquisition request to the primary EPG server to request session data, the primary EPG server may have timed out due to the corresponding session data. No indication is returned. In this embodiment, when the session module does not receive the indication information returned by the primary EPG server, the session module creates the session data of the IPTV terminal, and notifies the primary EPG server to update the session metadata information after the creation is completed, specifically Referring to the foregoing description, details are not described herein again.
