The aim of this review paper is to bring into light a potential area i.e., web services supply chains for research by analyzing the existing state of art in this. It is observed from the review process that there seems to be much less work done in the area of web service supply chains as compared to e-commerce and product oriented service supply chains. The service quality assurance models, end...

We address the QoS (Quality of Services) bandwidth reservation and service work scheduling mechanism of how to fairly provide advance quality of service in polling based TDM networks like Ethernet PON (Passive Optical Networks). Unlike existing differentiated QoS supporting schemes, such as SP (Strict Priority) based DBA(Dynamic Bandwidth Allocation) or static work scheduling with min-max theor...

Web services technology is critical for the success of business integration and other application fields such as bioinformatics. However, there are two challenges facing the practicality of Web services: (a) efficient location of the Web service registries that contain the requested Web services and (b) efficient retrieval of the requested services from these registries with high quality of ser...

Internet telephony imposes Quality of Service (QoS) requirements in terms of delay, jitter and loss ratio to provide reliable, high-quality multimedia services. While the Internet has historically offered a best effort service, it is hard to satisfy the required QoS of multimedia applications. In order to provide a tight QoS guarantee to telephony services, priority must be offered to real-time...

With the increasing deployment of functionally similar web services by different service providers, nonfunctional aspects, which are often referred to Quality of Service (QoS), play a vital role in ranking web services. Various users may have different priorities of QoS attributes. However, ordinary users are lacking in the ability to map their plain requirements to the obscure technical QoS me...

Flexible and adaptive quality-of-service (QoS) is desirable for distributed real-time applications, such as e-commerce, or multimedia applications. The objective of this research is to dynamically instantiate composite services by effectively utilising the collective capabilities of the resources to deliver distributed applications. Related to this objective are the problems of: (1) predicting ...

Long Term Evolution (LTE) has emerged as a comprehensive evolution of the Universal Mobile Telecommunications System (UMTS). In this paper, a Quality of Service (QoS)-guaranteed cross-layer resource allocation algorithm for multiclass services in LTE system is proposed. Numerical results demonstrate that the proposed algorithm can provide better behavior for QoS-based services than other previo...

Research reported here deals with a communication architecture with guaranteed end-to-end quality of service (QoS) in an IPv6 environment providing differentiated services within a single DiffServ domain. The article successively presents the design principles and services of the proposed architecture, their implementation over a national platform, and experimental measurements evaluating the Q...

Formal specification of various constraints, including quality of service (QoS) and price, is very important for successful dynamic (i.e., runtime) composition of Web Services. For specification of these constraints, it is important to formally define QoS metrics, measurement units, and currency units used. Ontologies provide a mechanism for such formal definition. In this paper we discuss some...
