For China modern communication, the switch can be said to be a barometer and one of the most basic facilities for communication construction. In the early 1980s, China just took the step of reform and opening up and began to build modern communication. The first high-tech project introduced by the state from abroad was the SPC exchange of Shanghai Bell. Today, 30 years later, China's modern communication has developed to a brand-new stage, and the competitive situation of switches and the demand of switch market are ever-changing. So, is there any chance for the exchange network, and what is the prospect? Automatic telephone exchange has developed from "electromechanical" mode to "program-controlled" mode, which is another major change in telephone communication in the 20th century. The next generation network is an operational, maintainable and manageable communication network represented by softswitch and based on IMS, which can flexibly provide large-scale video, voice data and other communication services for the public, take packet switching as a unified service bearing platform, and the transport layer adapts to the characteristics and bandwidth requirements of data services, which is related to communication operators.
