Description
Technical Field
The present invention relates to the field of data processing, and in particular to a data processing system for a conference.
Background
The current hot-standby scheme mainly includes the following modes:
(1) Master-slave mode: the mode slave node automatically synchronizes the data of the master node, and realizes the hot backup of the data. When the master node fails, the designated slave node needs to be actively switched to be a new master node.
(2) Sentinel mode: according to the mode, a monitoring system is added on a master-slave mode, fault transfer is achieved, the sentry nodes monitor the operation state of the master-slave nodes, and after the master node goes offline due to fault, the sentry nodes select one slave node to serve as a new master node to continue providing services.
(3) Cluster mode: according to the mode, a monitoring mechanism and a data slicing mechanism are added on a master-slave mode, fault transfer and data horizontal expansion are achieved, a plurality of masters and slaves are combined in a cluster, each master node is responsible for storing part of data in the cluster, and when a certain master node goes offline due to fault, the cluster can select one slave node of the node to serve as a new master node and continue to provide service.
However, the simple master-slave mode needs to define the master-slave relation in advance, needs active switching when in fault, and cannot adapt to the scene needing automatic switching; the sentinel mode is suitable for the scene with less data quantity, but single-point faults of the sentinel nodes exist, and a sentinel cluster is generally required to provide service; the trunked mode has stability and expandability superior to the sentry mode, but the use mode is complex. Thus, none of the above three modes are applicable when there are scenarios such as conferences where resources are limited and flexible automatic failover is required.

The main processing module determines the connection state of the terminal equipment and the main processing module based on the registration packet and the heartbeat packet sent by the terminal equipment, for example, a TCP interception server is started for determination. If the connection is successful, the connection state of the terminal equipment is identified as a first state, and if the connection is failed, the connection state is identified as a second state.
After the terminal device is registered on the main processing module, the main processing module generates a corresponding registration list, the r-th row of which includes (r, id) r ) R is the serial number of the r-th terminal equipment in the registration list, and is determined based on the registration sequence; id (Id) r And r is a unique identity of the r-th terminal equipment, and the value of r is 1 to m.
