A Virtual secondary school classroom on the Net

This chapter presents an application level network service based on the TCP/IP reference model. Our service is made of both a new Co-operative Activity Control Protocol (CACTP) and a new Application Program Interface. This service was used for the creation of an Interactive Multimedia Tele-learning Environment, which supports a visual secondary school classroom where the children and the teacher join a synchronous class session in Internet/Intranet networks.
