specific Embodiment approach
[0015] Each functional module and module communication of the virtual encryption card are as follows:
[0016] Among them, the load balancing module, the redundancy module, the work scheduling module and the monitoring module are modules that are always running, and the other modules are interface modules (interfaces for application and management calls).
[0017] Load balancing is only responsible for the load balancing of each encryption card. The current load of each encryption card is recorded based on the amount of requests being processed by the encryption card. Each request will be distributed to one or several encryption cards with the smallest load in parallel according to whether it can be processed in parallel. (job scheduling module).
[0018] The work scheduling module schedules and completes the requested processing work according to the allocated card resources (which encryption cards), keeps the results that need to be kept and intermediate results, such as key...
