摘要： 构建IPv6 over DVB体系框架，可以在下一代互联网中利用卫星等广播信道实施远程教育。该体系框架包括“支持IPv6的教育资源管理与发布系统”、“IPv6 over DVB传输系统”以及“IPv6 over DVB在远程教育中的应用示范”3个部分。实现了将IPv6互联网中的教育资源通过卫星链路发布到目前尚无网络覆盖的1 000所农牧村中小学。给出了设计方案和部署策略。

Abstract: A new architecture is proposed to deploy IPv6 over DVB in distance education. This architecture includes three parts. The first one is management and distribution system of education resources, the second one is IPv6 over DVB transmission system, and the last one is deployment scheme. Education resources scattered in different areas are packed into IP packets and transmitted to 1 000 country elementary schools by these systems on satellite. The details are presented.
Key words:
