DISTRIBUTED DEPLOYMENT AND CENTRALIZED CONTROL CABLE TELEVISION NETWORK BROADBAND ACCESS SYSTEM

The present invention provides a cable TV broadband access system with distributed deployment and centralized control, which comprises: a system terminal end, configured to receive and transmit uplink and downlink service data, and receive and respond to access control data and management control data; a system access end, configured to implement data format transformation and data forwarding or processing for said uplink and downlink service data, said access control data and said management control data of said system terminal end, and transmit, receive and respond to management control data of said system access end; a system head end, configured to implement management control and access control for said system access end and said system terminal end, and process, converge and forward said uplink and downlink service data. Said system uses a system architecture with three-stage distributed deployment and centralized control comprising a system terminal end, a system access end and a system head end, and it can not only realize the end-to-end control management and QoS priority assurance of the broadband data service, but can also realize easy network deployment, low comprehensive cost and high management efficiency.
