The Research Of The Construction Plan Of Digital Network In Dongling District

Because of the Internet information and the service content are enormous rich. The demand of users to enter the net is growing sharply. The wide band application purpose is mainly for the receiving and dispatching mail, the downloading material, the browsing website, chats with people, play the on-line game, VOD and so on. Due to The CNNIC statistics, the Chinese wide band user's population broke through15 million in 2005. But our country wide band user's popular rate only has 2% now, the international telecommunication alliance (ITU) just announced: The global top two country, South Korea and the Chinese Hong Kong area's family wide band popular rate respectively was 21% and 15%,we can tell, the Chinese wide band market has a very big room for growth.The Dongling cable TV network covers the whole Shenyang city's five areas, the Dongling district, Hun Nan newly developed district, He Ping district-Chang Bai area, Shen Bei newly developed district-agriculture high newly developed area, the Qipanshan traveling development zone, altogether supposes 9 machine stations, the network extend all directions, has the cable TV numeral service, the increment service development plat-form.This article formulated under this kind of big environment has planned the Dongling area numeral wide band network concrete implementation on plan. Using the optical fiber network which has, the construction wired wide band has turned on the net, the double platform network which the realization cable TV and the data wide band service coexists.The article first briefed the cable TV network data wide band present situation, the market demand and the cable TV network development numeral wide band service superiority. Then the elaboration the technical plan which should be used under the factor, Turns on the technology take the Ethernet as the leadership. How including chooses the network equipment, how realizes costs, the authentication, how does the stroke molecular net, how plan the IP address, how completes the route agreement, the QoS grade of service, as well as the threat and the risk guard and the anti-radar system design, finally proposed Dongling wired wide band network implementation concrete plan. In order to solve the Dongling cable TV wide band network,the existing city plot wiring's difficulty, this plan also proposed to use the CableWay series product, utilize the existing realized wired to turn on the net transmission data wide band service to concrete the implementation plan.Dongling area wired television station existing more than 60,000 cable TV user, through this plan's implementation, the wide band user quantity will achieve 20% accounts of the existing cable TV user, it may create the yearly income increase to 10 million Yuan, which is double size of current income. The investment is only about 10 million Yuan, and will recoup the outlay of capital in three years.This Plan's implementation, not only in the social effect but also in Economical point of view will provide a good development space to the Dongling wired television station. Create a glorious future for the Dongling wired television station.
