QoS Management within High Speed Transport System
نویسنده
چکیده
A high speed transport system must be able to manage the Quality of Service (QoS) requirements of multimedia applications. QoS management functions in this paper are related to OSI management functional areas and RACE telecommunications management requirements. We discuss especially management functions for QoS translation, admission control and resource management, monitoring and accounting using a common QoS oriented management information base (MIB). We focus on design and implementation aspects of QoS oriented MIB used by the management functions. A practical implementation of QoS management is based on eXpress Transfer Protocol eXtended (XTPX) in an internetwork environment including ATM. We investigate translations of transport user QoS interfaces to ATM networks and discuss admission functions in respect to different QoS interfaces. This paper addresses a practical approach for provision of management services on demand based on SPECTRUM network management tool. We discuss the use of SPECTRUM application views on XTPX QoS oriented MIB objects for configuration, performance and accounting management decisions.

Layer Integrated Quality of Service Management
Emerging high speed networks give rise to new classes of applications like teleconferencing or video-on-demand which demand Quality of Service (QoS). To provide QoS support on an end-to-end basis, the demand of integrating network, transport, and operating system appears since applications compete for network access, processor time and QoS guarantees. This paper discusses QoS requirements to th...
متن کاملManaging FDDI in a High Speed Multi- Network: the QoS Application
In this paper a set of Quality of Service criteria is proposed that enables the monitoring of any network element. For QoS computation the service management information model is instantiated with these QoS criteria. Emphasis lies on the FDDI network management considered as a component of a high speed multi-network. The lacks of the current FDDI management architecture for providing the necess...
متن کاملImplementation and evaluation of the QoS-A transport system
The long awaited Ônew environmentÕ of high speed broadband networks and multimedia applications is fast becoming a reality. However, few systems in existence today, whether they be large scale pilots or small scale test-beds in research labs, offer a fully integrated and flexible environment where multimedia applications can maximally exploit the quality of service (QoS) capabilities of support...
متن کاملFlow Management in a Quality of Service Architectures
Quality of Service (QoS) in distributed systems supporting real-time and multimedia applications must be guaranteed system-wide, including end-systems, communications systems and networks. This paper concentrates primarily on the transport layer of such a system but also describes a generalised Quality of Service Architecture (QoS-A) used to specify and implement application defined QoS over al...
متن کاملImplications of Self-Similarity for Providing End-to-End QoS Guarantees in High-Speed Networks: A Framework of Application Level Traffic Modeling
This paper is based on two novel research movements in the context of modeling, design, control, and management of future high-speed networks: (i) end-to-end QOS guarantees and (ii) the self-similar (fractal) nature of real-world traac. The former pertains to building an integrated framework within which end-to-end QOS guarantees are fully supported in an eecient way while taking advantage of t...
