在介绍一种用在高速通道中传播数据的选择式广播技术的基础上，设计了一个具有两个连接器的高速数据分布系统模型，并进行了仿真。模型由数据库接口网络和用户接口网络组成。前者负责从中心数据库传播信息到服务器；后者负责从服务器传播信息到用户终端。模型中的数据库接口网络就使用了选择式广播技术。从设计的模型和仿真的结果来看，选择式广播技术在正常条件下的时延比非选择式广播技术（如数据循环系统）要短得多。
Based on the introduction of a selective broadcasting technology used to transmit data in high-speed channels, a high-speed data distribution system model with two connectors is designed and simulated. The model consists of a database interface network and a user interface network. The former is responsible for transmitting information from the central database to the server; the latter is responsible for spreading information from the server to the user terminal. The database interface network in the model uses selective broadcast technology. Judging from the model of the design and the simulation results, the selective broadcast technology has a much shorter latency under normal conditions than non-selective broadcast technologies such as the data circulation system.
