And finding a service node according to the distribution result of service management when the calling party uploads/downloads the file, and performing actual file processing.
1) Load balancing strategy based on service management
In the invention, after the multimedia data management service node is started, the functions supported by the service are automatically discovered, the registration message is generated, the self functions are broadcast and sent to the service management module through the MQ, the probe is added, and the self load of the node is reported to the service management module. The service management module collects the information of all nodes in real time, sorts the nodes according to the sequence from low to high, returns the information sorted in real time when the service management interface is called externally, and the calling party finds the information of the interface to be called actually from the address list and carries out file operation.
