The embodiment of the invention is applied to specific IPTV multi-screen services, and mainly comprises the following contents:
two core modules for implementing the above data processing technology: one is an access network element device, specifically an access server; the other is a registered network element device, specifically a registration server, and the functions of the two modules are respectively:
accessing a server: and the system is responsible for balancing the access load of the terminal and the set-top box and distributing the registration server.
The registration server: and the terminal is responsible for acquiring and maintaining the information of the terminal user, including registration and keep-alive.
The access server only has one in the system as a single point, and the reliability of the access server is ensured by adopting a dual-machine mode. The functions of maintaining a registration server and processing access information of a terminal user are mainly carried out.
The registration server bears the management of the terminal data, and the registration servers are distributed to manage the terminal data. Multiple registration servers in the system are managed by the access server and, when the registration servers are started, will register in the access server, report its own information, the access server maintains the relevant information of the registration server in the system, and assigns an ID value to each registration server, the maintained information is then pushed to all registry servers, so that all registry servers in the system know the information of other registry servers, when the registration server is abnormally hung up or a new registration server is added, the access server will re-assign a new ID value to each registration server, then timely informing other registration servers, and through the distributed control mechanism, for the change situation of the registration server in the system, other registration servers can sense the change in time and automatically migrate the terminal data according to the change.
When a terminal such as a set-top box and the terminal is started up, an access message is firstly sent to an access server for access, after the access server receives the access message of the terminal, a hash value is calculated according to a Device ID of the terminal, then a registration server with the ID value closest to the hash value of the terminal is selected and returned to the terminal, and in the return message, the access server returns an IP address and the hash value of the registration server to the terminal. After receiving the return message of the access server, the terminal saves the address and the hash value of the registration server, sends the registration message to the registration server, reports the information of the terminal, and the registration server establishes an index in a memory according to the Device ID of the terminal, saves and maintains the information of the terminal. The subsequent terminal sends heartbeat to the registration server at regular time, and the heartbeat message reports the hash value to the registration server.
The embodiment of the invention mainly realizes the migration of user data among the registration servers when the registration servers are increased or decreased through the matching of the access server, the registration server and the terminal of the multi-screen gateway, and simultaneously realizes the migration of the heartbeat message sending of the terminal. For the registration server, when the terminal maintains the online state information of itself through the heartbeat message, the heartbeat message of the terminal carries the hash value calculated by the access server for the terminal, the registration server analyzes the hash value in the message after receiving the heartbeat message, then checks whether the hash value of the terminal is closest to the ID value of the registration server according to the information of all the registration servers in the system maintained by itself, if the registration server changes during the heartbeat message of the terminal, because the access distributes a new ID value to the registration server again, the hash value of the terminal is probably closest to the ID values of other registration servers, therefore, the terminal needs to migrate under the condition, the registration server returns a new registration server address to the terminal in the return message of the heartbeat message, and deletes the relevant information of the terminal in the memory of itself at the same time, after receiving the message, the terminal will register and keep alive heartbeat with the new register server again, and the information is maintained by the new register server
As shown in fig. 6, a complete process of a specific application scenario to which the embodiment of the present invention is applied is shown, where an access network element device is specifically an access server of a multi-screen gateway, and a registration network element device is specifically a registration server of a multi-screen gateway, in this application scenario, two registration servers are taken as an example, and there are no two registration servers in practical application, and the process includes a preprocessing step of starting the access server and performing monitoring on a specific port, and further includes the following steps:
601, the registration server starts up, establishes connection to a monitoring port of the access server, and reports registration related information of the registration server; and the registration server sends heartbeat messages to the access server at regular time to maintain the online state information of the registration server.
Here, the heartbeat message tells the access server that the registration server is still alive because the message is sent every fixed time like a heartbeat. That is, the heartbeat message is transmitted in order to confirm a fact that both the interconnected parties are on-line without communication for a long time or that a communication link existing between the interconnected parties has been disconnected. Once established, the connection can only be broken abnormally or normally, and not because there is no data transmission.
Step 602, after receiving the registration related information of the plurality of registration servers, the access server stores and maintains the registration related information in the access server, and assigns an ID value to each registration server.
Step 603, the access server pushes the relevant information of the registration server maintained by itself to all the registration servers, so that each registration server knows the relevant information of other registration servers in the system.
Here, the case where the number of registration servers is reduced includes: when the registration server is hung abnormally, the access server can judge whether a certain registration server is abnormal or not through whether a connection (such as a TCP connection) exists or whether heartbeat is overtime or not, and if the connection is abnormal, an ID value is reassigned to each registration server and other surviving registration servers are notified.
Here, the case where the registration server is added includes: when a new registration server is added, the newly added registration server can automatically establish connection with the access server and report the state information of the newly added registration server, after the access server receives the reported information, the information of the newly added registration server is added in a registration server list maintained by the access server, meanwhile, the hash value is recalculated for each registration server, and the related information of all the registration servers is pushed to the registration server.
And step 604, when the IPTV terminal accesses the multi-screen gateway system, applying for access to an access server through the access message.
Step 605, the access server calculates a hash value according to a Device identifier (Device ID) of the terminal, selects a registration server whose ID value is close to the hash value of the terminal, and allocates the registration server whose ID value is closest to the hash value to the terminal.
Step 606, the access server sends a return message to the terminal, where the return message carries the IP address of the registration server whose ID value is closest to the hash and the hash value calculated in step 605.
Here, the terminal subsequently queries the registration server via the IP address to be able to initiate a registration message with the registration server.
Step 607, after receiving the return message, the terminal stores the hash value and registers to the registration server.
And step 608, the terminal sends the heartbeat message to the registration server periodically to keep alive, and the hash value stored in the step 607 is carried in the heartbeat message.
Step 609, the registration server sends the incremental or decremental change and the access server reassigns a new ID value to each registration server.
Step 610, the access server sends a new ID value that is reassigned for each registration server.
Step 611, after receiving the heartbeat message sent by the terminal, the registration server analyzes the hash value in the heartbeat message, and reconfirms whether the hash value is closest to the ID of the registration server; if not, go to step 612; otherwise, the current connection is saved without processing.
Step 612, sending a heartbeat reply message, where the message is used to notify the terminal that the message needs to be re-registered, and the heartbeat reply message returns the new IP address and hash value of the registration server to the terminal, and meanwhile, deletes the relevant information of the terminal in the memory.
Step 613, the terminal judges the hash values obtained before and after the comparison (one hash value calculated by the server obtained in step 606; and one hash value calculated by the registration server obtained in step 612, and the calculation rules of the hash values are the same), if the hash values are the same, the migration is not needed, and if the hash values are not the same, the terminal is required to perform data migration, and the data migration is performed.
Step 614, the terminal receives the heartbeat reply message, and the message is used for notifying the terminal that the terminal needs to register the message again, and then the terminal registers the message with a new registration server.
And step 615, sending heartbeat messages to keep alive.
Here, step 613 may or may not be present; step 614 and step 615 may occur simultaneously or in a sequential order as shown in the present flow.
