We designed a kind of data broadcast system based on HFC network without return paths. 我们针对缺乏回传通道的传统有线电视网络,设计了一个基于HFC的数据广播系统。
Data Broadcast System Based on Local Area Network 基于局域网的数据广播系统的设计
The relay needs to receive data from the two terminals, combine the two data streams by network coding and broadcast the network coded signals to the two terminals. 中继先从二个终端接收信息,把接收到的二路数据采用网络编码合并之后广播给二个终端。
Data broadcast efficiently utilize the bandwidth asymmetry of mobile network, broadcast periodically the popular data and solve the problem of numerous clients availably. 数据广播充分利用移动环境中网络带宽的非对称性,周期性的将热点数据广播出去,有效地解决了移动端用户规模庞大的问题。
The data is transmitted mainly by the broadcast in existing network visualization system, and excessive network resources will be wasted in this way. 现有的网络可视化系统主要采用广播的方式传送数据,可是这种方式过度的浪费网络资源。
