The present paper introduced the wide band metropolitan area network concept, the stratification structure, the network technology briefly; Provides ADSL, ETHERNET, SDH, and so on the service types, as well as these basic essential factors in the network planning application, the wide band metropolitan area network technology select the principle.In this foundation, unifies Zhanjiang's situation to carry on the plan design to the Zhanjiang wide band metropolitan area network, introduced the local area network turning on service several realization way, and has made some discussions to the wide band metropolitan area network trend of development.In recent years, had the significant breakthrough take 10G SDH and the DWDM technology as representative's fiber optic transmission technology, the backbone network band width from Gb/s to the Tb/s development; In enterprise and inhabitant subscriber's premises network speed, but then enters the commercial use along with G bit ethernet technology toward the Gb/s development.These two tendencies caused the city territory transmission network to have the huge band width pressure and many kinds of new function demand.
差不多就这样 楼主自己在感觉下嘛 我们的 只能给你参考 祝你好运~@@~

The present paper introduced the wide band metropolitan area network concept, the stratification structure, the network technology briefly; Provides ADSL, ETHERNET, SDH, and so on service types, as well as these base elements in network planning's application, the wide band metropolitan area network technology select the principle. Based on this, unifies Zhanjiang's situation to carry on the plan design to the Zhanjiang wide band metropolitan area network, introduced that the local area network turning on service several kinds realize the way, and has made some discussions to the wide band metropolitan area network trend of development. In recent years, the technology had the important breakthrough take 10G SDH and DWDM as representative's fiber optic transmission technology, the backbone network band width from Gb/s to the Tb/s development; In the enterprise and the resident subscriber's premises's network speed, enters the commercial use along with G bit ethernet technology, but to the Gb/s development. These two tendencies caused the city territory transmission network to have the huge band width pressure and many kinds of new function demands.

This paper briefly introduced the concept of broadband MAN, hierarchical structure and network technology provided by ADSL, ETHERNET, SDH, such as type of business, and these basic elements in the application of network planning, the choice of broadband technology MAN Principle. On this basis, the combination of Zhanjiang City of Zhanjiang on the design of broadband MAN planning to introduce several of the LAN access business to achieve, and the development trend of broadband MAN was some discussion. In recent years, 10 G SDH and DWDM technology as the representative of optical transmission technology has a major breakthrough in the backbone network bandwidth from Gb / s to the Tb / s development of enterprises and residents in the client's network rate, as the G-bit Ethernet Technology into commercial applications and to Gb / s development. This trend has two metro transport network produced a huge bandwidth pressure and a variety of new functional requirements.
