QOS Control of Continuous Media : Architecture and System
نویسنده
چکیده
In an interactive multimedia environment that handles multiple sessions dynamically, a mechanism for controlling the Quality of Service (QOS) among sessions is very important. The QOSControl Server described in this paper is such a mechanism, developed on RT-Mach. This paper gives the results of several experiments with this server, and describes the extensions of RT-Mach needed for e cient QOS control. The thread-model extension makes it possible to create a thread suitable for processing continuous media, and the CPU-reservation mechanism gives more e cient QOS control. In accordance with these experiments, a new QOS-control model based on \QOS-Ticket" is proposed. In this model, QOS control is achieved through cooperation of the operating system, the QOS Manager, and each continuous-media session. The QOS-Ticket, which represents the resource reservation for each session, mediates these activities.

QOS-Ticket: A New Resource-Management Mechanism for Dynamic QOS Control of Multimedia Kiyokuni KAWACHIYA
In an interactive multimedia environment that handles multiple sessions dynamically, a mechanism for controlling the QOS among sessions is very important. It is, however, di cult to achieve such QOS control without any system support. A new resourcemanagement mechanism and QOS-control architecture for multimedia applications are needed. This paper rst discusses features required for such archit...

Until recently the World Wide Web (WWW) and associated browser technologies have provided no support for the delivery of continuous media in real time. Instead, les have been down-loaded completely and then played back. There are now some systems available that provide support for streaming of audio and/or video between WWW servers and clients. However the Internet comprises a vast range of net...
متن کاملQoS Management in a Continuous Media Network System
In this paper, we describe the design and implementation of a suite of network protocols on a real time operating system that ensures the QoS (Quality of Service) of continuous media applications. The suite consists of a newly designed transport layer, a network layer that includes ST-II, a reservation-based network protocol, and a data link layer providing network access to ATM and Ethernet in...
متن کاملAn Architecture for Dynamic Multimedia QoS Control
The execution of repetitive tasks related with the handling of continuous media is something that should be detached as much as possible from multimedia applications. However, applications should have control over the most significant aspects of the process. This paper presents a framework to enable applications to exercise this control in terms of QoS concepts. Instead of defining low-level Qo...
متن کاملA Review of Quality of Service Architectures
The integration of distributed multimedia systems support into a communications architecture, including new multiservice networks, is important in realising end-to-end quality of service (QoS) guarantees. A key observation is that quality of service provides a unifying theme around which new QoS architecture can be constructed. For applications relying on the transfer of multimedia, and in part...
