User-to-User QoS
Martina Zitterbart · 1997
The rapid development towards networked multimedia applications leads to new and high requirements on the network as well 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 levels 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 well as several QoS management issues are discussed. Moreover, a QoS monitor as part of the QoS framework and its implementation is presented.
