Service-Oriented Architecture (SOA) provides a flexible framework for service composition. In a service market scenario, given a functional description of service, different providers may offer diverse service implementations that match such a functional description, but differ for some QoS attributes. It is increasingly vital to provide a service selection and recommendation mechanisms that best...
In this paper, we analyze the problems of existing Service Computing model and propose a closed-loop mechanism for service evaluating and discovering on the Internet which is not only compatible with the basic principles of Service Computing--loosely coupled, protocol independent and location transparent, but also can rank, classify and recommend services based on their real-time performance. This...
As more and more Web Services appear on the public Internet, Quality of Service (QoS) becomes one of the most important factors for Web Service selection. Meanwhile, accuracy and speed of Web Service selection come to be the new barriers. Focusing on those QoS attributes that are measurable on client-side, this paper proposes a new Web Service selecting model, extending the general searching architecture...
SOA has become more and more popular, but fault tolerance is not fully supported in most existing SOA frameworks and solutions provided by various major software companies. SOA implementations with large number of users, services, or traffic, maintaining the necessary performance levels of applications integrated using an ESB presents a substantial challenge, both to the architects who design the...
