According to the hierarchy of the business logic, the paper expounded the implementation mechanism of short message transmission and service, the network management interface protocol, and each monitoring business application. Furthermore, the paper analyzed possible performance issues in the application of the platform, and proposed two optimization methods from the view of software design, including dynamic multi-threading service and window-based flow control at the sender.This platform has been put into trial operation in Guizhou Telecom, and running stably. It meets the requirements of the daily network management of network operators, and has wide applications in future.
