The inventor found that the current address management methods mostly adopt centralized management methods. For example, when users access, the address pool module is unified and centrally managed for address allocation. Such management methods are executed serially, with low operating efficiency and layout. It is not flexible enough, and it is prone to address waste; or separate the address pool database to the upper application module and apply for free addresses in real time, and use the stored free addresses for address allocation during user access, although this improves user access efficiency , But it cannot achieve load sharing, and it is easy to cause uneven address allocation and cause address waste.

Based on this, this application provides an address management method that can be used in a distributed deployment method based on address pools. Multiple resource pool components receive address applications allocated by load balancing components, and perform user address allocation tasks in parallel when multiple users are connected. .
