Implementation of an Internet video conferencing application over ATM

The paper describes a complete implementation of an Internet video conferencing application taking advantage of the quality-of-service (QoS) capabilities provided by ATM. RSVP has been used to exchange the QoS parameters among the communicating video conferencing applications. The RSVP QoS parameters are mapped to ATM parameters and dedicated VCs with the corresponding ATM parameters are established by the underlying classical IP over ATM implementation. These VCs provide the desired QoS from the ATM network to the application data flow. The implementation is based on existing components such as an Internet conferencing tool, a RSVP implementation, and a classical IP over ATM implementation. The paper presents the required modifications of all these components to support QoS communication and the adaptation for their integration.
