Broadband IP MAN IP backbone network , the telecom operators in the building within the metropolitan area is the city's premier information infrastructure , telecom operators to obtain an important pillar of growth performance . In recent years, with the sharp increase of the size of the network continues to expand , and the number of users , the the original broadband IP network is increasingly unable to meet the requirements of the dynamic growth of the communications business development , defects and deficiencies of its network gradually manifested mainly in the network structure unreasonable , scalability, poor stability , lack of business support . This paper demonstrates how through optimal adjustment of the whole network , a state-of-the-art technology , security and stability , scalability , and with powerful IP network transfer capabilities and service functions . This paper described of Huzhou telecom broadband IP MAN optimize the transformation of the necessity , feasibility , network optimization , significance , and MAN optimize the transformation of the theory involved . Then, starting from the network structure , combined with operational practices , depth and detailed analysis on the status quo of Huzhou telecom IP MAN , pointed out that the problems existing in the network . Next, to address the problem , the proposed detailed optimization rehabilitation programs . Programs start from the the MAN physical network optimization , optimization of the core layer, convergence layer and access layer , to obtain advanced physical network , reasonable topology and flexible service delivery approach ; routing organization and IP address re- planning , network efficient dynamic protection while minimizing equipment overhead ; optimize the design of the entire network security policy , to further enhance the stability of the network . Finally, on Huzhou telecom broadband IP MAN optimization summarized, and MAN technology and business trends , prospects .
