Quality of service management in distributed multimedia systems
Guojun Lu · 2002
Real-time distributed multimedia applications have special requirements in terms of bandwidth, delay and delay jitters, etc. A notion of quality of service (QOS) is used for applications to specify these requirements and for the system to guarantee these requirements. To support the QOS notion, mechanisms to specify QOS requirements, QOS negotiation and renegotiation, admission control, resource management and policing are required. This paper describes the overall QOS framework and these mechanisms, and identify issues in providing QOS guarantees.
