User-to-User QoS

Abstract

The rapid development towards networked multimedia applications Ieads to new and high requirements on the network as weil as on the systems involved. Especially guaranteed Qualityof-Service (QoS) is required for certain applications with isochronous data streams or with highly interactive characteristics. Therefore, an integrated systemwide QoS management is needed. Among others, issues such as mapping of QoS parameters between fundamentally different Ievels of the system (user, application, network) and QoS monitoring are very important. This paper presents a framework for QoS management. Requirements of networked multimedia applications as weil as several QoS management issues are discussed. Moreover, a QoS monitor as part of the QoS framework and its implementation J.s presented.
