(Tianwei video network carries more than 800000 IP users, with 300000 online users and more than 13g Internet export traffic. It can provide users with integrated services such as interactive TV, high-speed data and VoIP. Through the Hanbai flow control system scheme, P2P downloads and network TV are diverted to static ISP lines in the late peak hours, greatly reducing the bandwidth pressure of the original BGP link and optimizing the bandwidth use. It provides effective technical support for the next expansion of the export link and reduces the expansion cost. At the same time, through the combination of radius and flow control system, the correspondence between IP address and user account is realized. Tianwei video can implement strategies such as guarantee and restriction according to the traffic, bandwidth, time period, application type and other parameters of end users, so as to lay a foundation for the development of personalized bandwidth services, home video phone terminals, and the integration of cable TV / broadband / telephone multi services in the future.)
