Delivery of Distance Learning Content Across High-Speed and Low-Speed LANs in a Campus Environment

David H. Dirks, Doug Coffland

While distance learning technologies have been in existence for over 30 years, new forms of transport and delivery are required to provide asynchronous or “just-in-time” instruction. Advanced Local and Wide Area Networks (LAN's, WAN's) allow distance learning content to be delivered in the form of video-on-demand to the corporate employee at any time and virtually anyplace. The Advanced Video Research Project (AVRP) at Lawrence Livermore National Laboratory (LLNL) is developing applications and tools to transport compressed video and audio content across low-speed and high-speed LANs to the employee desktop. Our efforts include finding cost-effective means to deliver MPEG-1 compressed content via 10 Mbps ethemet, 25 Mbps ATM, and 155 Mbps (OC-3) ATM. We are testing and evaluating commercially available systems. In addition, we have developed a custom user application and interface.
