Design And Optimization Of China Mobile Changchun Suburban PTN Network

Nowadays, communication network has been an important transformation, it can be said to be an important direction of development, that is, the carrying capacity of the communication service network gradually IP and traditional bearer gradually grouping. So the current three major carriers that are mobile, telecom, China Unicom are starting to focus on how to adapt to the use of packet delivery technology for efficient transmission and carrying capacity. In order to solve the problem of load and speed of IP service in communication, the packet transport network is a good solution for PTN technology, and this technology has become an important choice for operators to choose the main transmission network. In this paper the packet transport technology for the actual situation of in-depth and comprehensive study based on combined with Jilin Mobile suburban branch of PTN network, for network planning and an example is given.This paper first systematically and comprehensively expounds the development, principle, system and structure of the packet transport network, and the main technology of packet transport network, including synchronization, protection and control maintenance. Then the in Changchun mobile suburban company suburban company now, the scale and structure of network of detailed analysis, and the business network data service bearing based on research needs, the network planning design, to establish the implementation of Changchun mobile suburban transport network PTN technology dominant network building strategy and principles, in focusing on the quality of service, network resources and network security construction scheme of the three aspects of the design core layer, convergence layer, access layer network construction program. Packet switching network is a multi service transmission platform, the construction scheme is fully considered in the paper. The problem is analyzed, and the network optimization scheme is given. The problem is analyzed, the network optimization scheme is given, which is based on the problem of network optimization.Through optimization, enhance the suburban company in Changchun mobile PTN network into a ring rate and double return rate, the whole network into a ring rate reached 73%, than that before optimization into ring rate of 11% increased 62%. Double return rate reached 88. 82, optimization of double return rate of 5% to elevate the 83. 82%, reduced due to transmission interruption of business interruption caused by long, was to promote and improve the quality of the Changchun municipal PTN network.
