Abstract:
Teleteaching has become an important application of the Internet and the MBone. Unfortunately the costs for the hardware, necessary to participate in remote lectures, are still prohibitively high and the degree of distributiveness of the implemented scenarios is very low. In the Interactive Home Learning project we plan to provide methods to participate in a Teleteaching lecture live from a PC at horne via a low-bandwidth connection (e.g. ISDN). This paper summarises technical aspects of this learning scenario and presents our approach, the fully Java-based Reflection and Scaling Tool jrst, which meets the requirements of an application layer multicast routing demon with a highly restrictive broadcasting policy and a dynamic tunnelling mechanism.
