Technical Field

Background
The existing current limiting technology defines the concept of resources and rules for a system, wherein the resources are codes needing protection, and the rules are access control rules, fusing degradation rules, system protection rules, hotspot protection rules and the like. And in the system operation, the flow condition is monitored in real time, and the protection effect on the existing system is realized according to the flow rule.
When the existing flow prevention and control system is actually used, the definition of resources needs to be preset and points are buried in advance. That is, in the development and design stage, the resources of the traffic hot spot need to be identified, so that the hot spot is predicted in advance and the rule is set.
