Research Of Key Problem Of Telecom Local Transit Network Optimization

The telecom trades of China has got continued and fast speed development since the reform and opening, and brought about historic stride a crossing. The trade of telecom and information services has become one of the fastest speed development trades in the national economy department. According to the vocational requirement and the market application, the telecom trades will make a biggest and deepest change in the future make a strategy change from phone business to digital business. The requirement from the users including the reliability of the telecom network and the video business has made a clearly increase. Obviously, our network no matter from our scale,technical levels,structure and service quality can not support such requirement. So we should develop and build next generation network of huge capacity,high reliability,flexible and stainable development.Though there have essential changes from the business and market in the telecom trades. It will bring us to renew our telecom network. It is an opportunity and challenge to every telecom operator. The paper first described the development and status of the transit network of Shenzhen telecom. Then against the change of the market requirement,and analyze the bottleneck problem of the transit network in the business dispatching. analyze the resource of the network can not contended to the market requirement, analyze the cause of affecting the network safety running, and combine to the tendency of the technical development of telecom transit network. The paper put forward a series of solution plan, such as how to extend our network to support the increased requirement of the traditional business, and how to reform our present network to Multi-Service Transport Platform(MSTP) to lighten the pressure of the increased requirement of the optical fible resource. Last the paper suggest that Shenzhen should plan to build Metropolitan Area Network base of DWDM technology and the network should have huge capacity and high reliability to running and it can unify to dispatch the business flexibility.
