This Recommendation specifies performance requirements and objective measuring methods of quality of service (QoS) for the delivery of digital video broadcasting services over broadband Internet protocol (IP) networks. The specified performance requirements are based on an IP QoS ranking at various levels, from “excellent” to “out-of-service”. They rely on the objective end-to-end measurement o...

The arrival of ubiquitous computing environment, while providing services in many devices and users has been a lot of movement. In this environment, users want „seamless‟ service. A lot of mobility in ubiquitous computing environment to provide „seamless‟ service to users, many studies was used to substitute the service. An existing service substitution does not considerate the characteristic o...

Quality of Service (QoS) guarantee is an important component of service recommendation. Generally, some QoS values of a service are unknown to its users who has never invoked it before, and therefore the accurate prediction of unknown QoS values is significant for the successful deployment of Web service-based applications. Collaborative filtering is an important method for predicting missing v...

As the number of Web services with the same or similar functions increases steadily on the Internet, nowadays more and more service consumers pay great attention to the non-functional properties of Web services, also known as quality of service (QoS), when finding and selecting appropriate Web services. For most of the QoS-aware Web service recommendation systems, the list of recommended Web se...

The immense growth in internet technologies leads to increase in size of the web service repository. Normally, all the service requestor expects very qualitative resultant web service for their request. These requestors may not have previous knowledge about their requesting domain. So it is difficult for them to filter out the relevant web service from huge pool of data. Moreover, the resulting...

In this paper analyzes various scheduling algorithms applied to multi-media streaming system for providing real-time service in Internet and proposed a scheduling algorithm that can meet the QoS requirements of delay-sensitive traffic and loss-sensitive traffic for specific services. First, the concept of QoS drafted from the recommendation of ITU-T is defined and the requirements for packet mu...

Web services are integrated software components for the support of interoperable machine-tomachine interaction over a network. Web services have been widely employed for building service-oriented applications in both industry and academia in recent years. The number of publicly availableWeb services is steadily increasing on the Internet. However, this proliferation makes ithard for a user to s...

With the increasing number of Web services on the Internet, selecting appropriate services to build one’s application becomes a nontrivial issue. When searching Web services, users are often overwhelmed by a bunch of candidates with similar functionalities. Quality-of-Service (QoS), the non-functional characteristics of Web services, has become an important factor to distinguish the functionall...

With the growth of Web Services number and with the diversification of their types and qualities, the choice of the service that complies with user preference became a fundamental issue. The task of finding the best Web service is no longer an easy task and may end to unsatisfactory result. To resolve this problem, we adopt in this paper a Web services discovery and selection approach based on ...
