提出了一种在单向有线数字电视HFC网和IP网上采用软交换技术I、P技术的远程教育方法,并将该方法加以实现。通过软交换体系使HFC网和IP网能够互通互用,较好地解决了广播电视HFC网I、P网分别开展远程教育所带来的网络拥塞、时延、QoS保证及双向互动等不足,为远程实时教学提供了一种可行方案。
A new distance education method between HFC net in single direction CADTV and IP her is immoduced, which presents exclange teehnology in softswitch and IP technology, This system can be implemented perfectly, whieh overcome these, shortcomings, such as net congestion,delay and QoS Service.
