This paper presents the components of a synchronous teleteaching application, their underlying
technology and their interaction with network services. In addition, it presents the
architecture and design of a synchronous teleteaching application used over the public ATM
network in Greece. This paper presents various teleteaching scenarios over an ATM network
infrastructure with the use of native ATM and IP over ATM. In each scenario we present the
standards used, the logical components, the resource demands (network and equipment) and
its special characteristics. For each scenario we give detailed information about the transmission
and frame rates and the video delay. The main result of our experiments is that
broadband networks offer many capabilities for high quality teleteaching, and generally
speaking, high quality telematic services.
