Time and resource constraints often force developers of highly configurable quality of service (QoS)-intensive software systems to guarantee their system’s persistent software attributes (PSAs) (e.g., functional correctness, portability, efficiency, and QoS) on very few platform configurations and to extrapolate from these configurations to the entire configuration space, which allows many sour...

With quick advancement in web technology, web-services offered on internet are growing quickly, making it challenging for users to choose a web-service fit their needs. Recommender systems save the hassle of going through range products by product recommendations analytical techniques historical data user experiences available items/products. Research efforts provide several methods recommendat...

Growing demand for differentiated services and the proliferation of Internet multimedia applications requires not only faster switches/routers, but also the inclusion of guaranteed qualities of service (QoSs) and support for multicast traffic. Here, the authors introduce a parallel shared memory (PSM) architecture that addresses these demands by offering both QoS guarantees and support for mult...

As Web services have become the grand vision these days, more and more people are seeking out the practicalities of implementing and using them for business benefit. Thus Web services make application functionality available over the Internet in a standardized, programmatic way. QoS support for Web service has become a widely researched area and has shown to be an effective mechanism in Web ser...

Mobile real-time video streaming for web-casting and video conferencing conforming to the ITU-T H.264 data compression recommendations format is emergent. However, the quality of the video services for typical applications is hard to foreseen and sustain. Qualities of Services (QoS) approaches, such as video frame skipping techniques, are thus attractive to address the problem. Many conventiona...

Selecting an optimal service from a group of functionally equivalent ones is non-trivial. This is more so when the service to be selected is part of a composite application. Research in the past has resolved this issue making use of the Quality of Service (QoS) attributes of the services to determine the most optimal from the functionally equivalents. This paper too attempts to tackle this prob...

Computing clusters have been one of the most popular platforms for solving Many Task Computing(MTC) problems, especially in the case of loosely coupled tasks. However, building and managing physical clusters exhibits several drawbacks:1)Major investments in hardware, specialized installations, and qualified personal; 2) Long periods of cluster under-utilization; 3)Cluster overloading and insuff...

Design decisions for complex, component-based systems impact multiple quality of service (QoS) properties. Often, means to improve one quality property deteriorate another one. In this scenario, selecting a good solution with respect to a single quality attribute can lead to unacceptable results with respect to the other quality attributes. A promising way to deal with this problem is to exploi...

Modern day communication systems have gained a revolutionized growth in long-distance wireless data transmission. High speed packet transfer impacts quality requirements. Critical factors that ruin service (Qos) are calculated by the primary involving power efficiency, delivery ratio, and overall transmission reception delay. A well-developed routing protocol with unique attributes should be de...

Object-based storage systems (OSS) have evolved from the traditionally unintelligent management to intelligent and selfmanaged schemes by delegating low-level management activities to storage devices, and providing new functionalities, such as greater scalability and dynamic reconfiguration. An object consists of data, user-accessible attributes and device-managed metadata, which is responsible...
