本文提出了一种宽带分布式网络设计,该网络能在CATV电缆上同时进行数据、实时数字话音及模拟电视通信。本系统能支持大量用户间的通信。由于采用了宽带技术和总线网令牌与CSMA/CD的混合协议,从而解决了局域网所面临的距离和时延问题。本文最后对所提出网络的话音性能作了评估,所得结果与相关试验报导数据相符。
This paper presents a broadband distributed network design that enables simultaneous data, real-time digital voice and analog television communications over a CATV cable. The system can support a large number of user communication. As a result of the broadband technology and the bus network token and CSMA / CD hybrid agreement, which solves the LAN is facing the distance and delay issues. Finally, the paper evaluates the speech performance of the proposed network, and the results are consistent with the relevant experimental report data.
