Design and Implementation of Load Balancing Module of Substation Intelligent Gateway under Multi-service Access

The load balancing module of the multi-service access edge computing gateway of substation is designed. Based on the theory of software engineering, the analysis of module objectives and functional requirements, the overall design of system architecture and module functions, the realization of module functions and the testing of key functions are carried out respectively. The design is based on the node information collection module, the load calculation module and the load judgment module, and takes the scheduling module within the edge computing gateway node and the scheduling module between the edge computing gateway nodes as the core, realizing a complete control process from access management scheduling to load balancing, so that the workload of the edge computing gateway nodes in the region can be kept in the most balanced state. The test results show that the load balancing module of the substation multi service access edge computing gateway can judge the load of the currently accessed service terminal, complete the dynamic scheduling of the access association mode, make the association access always in the optimal state, and maintain the overall workload balance of the current intelligent gateway.
