Description

The data construct net of broadband services
Technical field
The present invention relates to broadband network field, specifically a kind of data construct net of broadband services.
Background technology
Along with the development of network communication and video compression technology, the broadband Video service such as video request program, video conference and online game are provided to become the main management developing direction of broadband services just gradually by broadband networks for domestic consumer.But far above voice and conventional data transmission, the data construct of broadband services to be had higher requirement because video content takies broadband.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of data construct net of broadband services, and ensure the stability of video and voice transfer, data network wide coverage, transmission rate is fast.
Technical scheme of the present invention is:
The data construct net of broadband services, includes data backbone, prefectures and cities' metropolitan area network and data access net; Described data backbone includes two 10,000,000,000 core routers, and two 10,000,000,000 core routers are connected with the Internet respectively by a kilomega firewall; Prefectures and cities' metropolitan area network includes prefectures and cities' egress router, two EMS distribution of media switches be connected with prefectures and cities egress routers, the Broadband Remote Access Server be connected with prefectures and cities egress routers and the convergence switch be connected with Broadband Remote Access Server, and each prefectures and cities egress router is all connected with two 10,000,000,000 core routers; Described data access net includes the EOC local-side device being connected OLT device, the ONU equipment be connected with OLT device with convergence switch and being connected with ONU equipment.
Described each prefectures and cities egress router is connected with 2 10,000,000,000 core routers by DWDM transmission network.
10,000,000,000 described core routers select 10,000,000,000 core router CISCOGSR12816; Described prefectures and cities' egress router selects router CISCO7609; Described kilomega firewall selects kilomega firewall ASA5580.
