The Optimization Design And Implementation Of Qinghai Branch Of China Telecom’s IP MAN

Broadband IP MAN is the bearer network of Telecom operators, which can transport the internet business within the city. Original Broadband IP MAN can not meet the requirements of the dynamic growth of communication services, because of its unreasonable network structure and poor ability of support to new business. It is necessary to optimize the IP MAN based on the principles and methods of optimization, then the companies can maintain a leading position and the operational capacity can be improved.To build a broadband IP MAN adapting the development of telecommunication services in Qinghai, optimal design and implementation of Qinghai had been researched.By analyzing the status of the business and network of IP MAN in Qinghai, the necessity and feasibility of reconstruction is proposed. The viable broadband IP MAN optimization program has been proposed through in-depth analysis of the current situation of Qinghai broadband IP MAN using the theory of related technologies. First, the three-tier network architecture including the core layer, convergence layer and the access layer was optimized and a reasonable network topology was established. And to improve the reliability of the network, the routing protocol was planned by choosing the mature and efficient ones. Then in order to achieve rapid deployment capability of new business, the VLAN identification is researched. Moreover, the QoS and security of IP MAN was improved to increase the robustness of the network. Finally, a detailed and operational optimization program of Qinghai broadband IP MAN was formulated. The target of having boutique network and high bearer ability of Qinghai will be achieved,through the implementation of the program.
