A Service Kernel for Multimedia Endstations

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 di erent domain speci cations (layerto-layer translation) and domain-resource speci cations (layer-to-resource translation); (2) Admission and Allocation of resources; and (3) Negotiation and Coordination of QoS speci cations among the distributed endpoints. For each service we propose architectural solutions. We are testing the service kernel with an ATM-based telerobotics application. 1 Problem Description Quality of Service (QoS) guarantees for delay sensitive networked multimedia applications must be application-to-application. Guarantees are achieved if: (1) the information is carried between end-points using delay-bounded communication protocols 6], 5], (2)...
