Packet Scheduling for Multimedia Tra c in a Resource-Partitioned Network
نویسنده
چکیده
We present a general purpose model and schedulability condition for supporting multiple service classes using bandwidth resource partitioning. The model supports guaranteed communication performance for real-time multimedia tra c via an Earliest Deadline First (EDF) packet transmission policy. We show how the EDF model can incorporate the e ect of multiple service classes sharing the same transmission link.

An Evaluation of Routing and Admission Control Algorithms for Multimedia Tra c in Packet-Switched Networks
Support for real-time multimedia applications is becoming an essential requirement for packetswitched networks. In this work, we investigated how routing and admission control in uence the performance of packet-switched networks. We propose and evaluate the use of routing algorithms which take into account the constraints imposed by the admission control algorithms. Routing algorithms proposed ...

متن کاملClass provisioning using proportional delay di erentiation
We consider the problem of link provisioning in a di erentiated services network that o ers N classes of service. At the provisioning phase, the network manager con gures the link to support the requirements of M distinct tra c types. Each tra c type is speci ed by an expected arrival rate and an average delay requirement. The objective of the provisioning phase is to jointly determine: the min...
