A service kernel for multimedia endstations

Abstract

Quality of Service (QoS) guarantees for delay sensitive networked multimedia applications, such as teleoperation, must be application-to-application. We describe a set of services, a service kernel, required at the end points, for multimedia call establishment with QoS guarantees. These services provide: (1) Translation among different domain specifications (layerto- layer translation) and domain-resource specifications (layer-to-resource translation); (2) Admission and Allocation of resources; and (3) Negotiation and Coordination of QoS specifications among the distributed endpoints. For each service we propose architectural solutions. We are testing the service kernel with an ATM-based telerobotics application.
