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 us...

User Services Assistant (USA) is a novel reactive QoS agent that provides facilities for managing user to user QoS in Internet environments. By being reactive, it overcomes the problems associated with QoS management schemes that have been proposed to date, such as the mapping of the QoS parameters to end system parameters, and pre-determining the optimum way of degrading/upgrading the QoS. How...

Quality of service (QoS)-enabled publish/subscribe (pub/sub) middleware provides powerful support for data dissemination. It is hard, however, to maintain specified QoS properties (such as reliability and latency) in dynamic environments (such as disaster relief operations or power grids). For example, managing QoS manually is often not feasible in dynamic systems due to slow human response tim...

Network Quality of Service (QoS) criteria of interest include conventional metrics such as throughput, delay, loss, and jitter, as well as new QoS criteria based on power utilization, reliability and security. In this paper we suggest a theoretical framework for the characterization and comparison of adaptive routing algorithms which use QoS as the criterion to select between different paths th...

Current quality of service (QoS) management approaches in real-time systems lack support for configurability and reusability as they cannot be configured for a target application or reused across many applications. In this paper we present the concept of a QoS aspect package that enables developing configurable QoS management for real-time systems. A QoS aspect package represents both the speci...

ABSTRACT In this paper, we investigate a new efficient quality of service (QoS) routing protocol based on the time-slot leasing mechanism over Bluetooth wireless personal area networks (WPANs). In a Bluetooth scatternet, a QoS route path is constructed through a series of QoS slave-masterslave communications. The ”transmission holding” problem is incurred because the master node is the communic...

Service-oriented architecture (SOA) middleware has emerged as a powerful and popular distributed computing paradigm due to its high-level abstractions for composing systems and encapsulating platform-level details and complexities. Control of some details encapsulated by SOA middleware is necessary, however, to provide managed quality-of-service (QoS) for SOA systems that require predictable pe...

Nowadays, Value Added Web Services (VAWS) are becoming a hot spot for web services providers. Quality of Service (QoS) support in VAWS is an important issue. The need for providing and assuring an acceptable level of QoS is the objective of most of service providers. Service providers compete in satisfying requirements of potential clients by providing QoS support of VAWS. In this work, we prop...

As a result of the rising popularity and necessity of real-time multimedia applications, Quality of Service (QoS)monitoring needs more attention in wireless networks. Due to infrastructureless and mobile nature of wireless mobilead hoc networks (MANETs), QoS monitoring is a challenging task. This paper extends our previously published workand provides a framework for a robust and a multi-metric...
