This is a survey paper on IP QoS over ATM. It describes the need for QoS in the Internet and the mechanisms of QoS provisioning in IP. ATM is briefly described with a view to highlight its inherent support for QoS. Then, mechanisms of providing IP QoS over an ATM network are considered. Also issues that arise in implementing the various IP QoS over ATM is considered. See Also: Quality Of Servic...

For a long time the proponents of the ‘best-effort’ Internet argued that the appropriate response to increased demand for bandwidth and resulting congestion is added capacity. Things have changed! In the last few years we have witnessed the demand for bandwidth to increase at a rate much faster than ISPs can handle. We have also observed a shift in application requirements for networkservices. ...

With the big success of 802.11 wireless networks, there have been many proposals addressing end-to-end QoS guarantees in 802.11 WLAN. However, we have found that current end-to-end QoS architectures lack of one or more important properties such as cross-layer interaction, end-to-end integration, reconfigurability and modularity. In this work, we present an end-to-end reference QoS architecture ...

The rapid growth and coexistence of different application domains, such as multimedia and electronic commerce, present a significant challenge to the provision of their Quality of Service (QoS). To solve this challenge, we need a unified QoS framework, which allows flexibility and reconfigurability. In this paper, we present a reconfigurable component-based QoS framework, called 2KQ, which solv...

In a growing web services environment, the usage, design and composition methods of web services require proper and reliable information about web services quality. QualityofService (QoS) is usually referred to the non-functional characteristics of web services which can be used as an important role to differentiate between different web services. In order to select the best web services among ...

The main objective of the model we describe in this paper is to allow easy, flexible addition of quality of service (QoS) control to Java Internet applications. In this work the QoS is expressed in terms of network and host resources, the network QoS being controlled with RSVP. Flexibility is provided by a prototype product from the ANSA research consortium; Reflective Java which uses the Meta ...

The introduction of the concept of QoS has led to an extension of the traditional concepts of service and service specification. However, design of QoS support is usually done without a systematic approach, leading to concepts of QoS support ranging from basic QoS monitoring capabilities to hard real-time guarantees. In more advanced QoS support, intermediate layers should be designed in a way ...

Developers of distributed real-time and embedded (DRE) systems face challenges in provisioning network quality of service (QoS) properties due to the presence of application flows that require a range of network-level QoS properties, as well as the complexity of specifying perflow network QoS requirements and mapping them to network QoS enforcement mechanisms. This paper describes a QoS-enablin...

Wireless Body Area Sensor Networks (WBASNs) applications have emerged as major type of Wireless Sensor Networks (WSN). Ample research work has already carried out to improve the QoS in WSN. However, QoS provision in WBASN needs further investigation. Majority of the research work in WBASN improves the QoS considering timeliness, latency or energy as a basic requirement. Most of the researchers ...

In this paper, a novel quality of service (QoS) prediction framework is proposed to accommodate different applications with various QoS requirements. The purpose of the proposed structure is to estimate, given the QoS requirements of different applications, the number of them can be satisfied according to the predefinedQoS level and the number of themhave to be rejected or accepted under lower ...
