Service Integration has become a critical issue as organizations find a greater need to consistently interact with their partners and share their Business logics to carry out the necessities. To accurately and efficiently extract and integrate the required service logics from the rapidly expanding Business services, developers need to empathize the whole service and must decide on proper approach...
Cloud computing is the next stage in evolution of the internet, which provides large amount of computing and storage to customers provisioned as a service over the internet. However, cloud computing facing so many security challenges due to the possible compromise or byzantine failures. In this paper, we focus on Ensuring data storage security in cloud computing, which is an important aspect of Quality...
In this paper, we introduce an IP Multimedia Subsystem (IMS) based testbed which provides a platform for service innovations. This open-source based testbed is built on the principle of Service Oriented Architecture (SOA), whereby system functionalities such as bandwidth management and video streaming are packaged as interoperable services, so that service providers can combine and reuse them through...
This paper proposes a service selection solution named ZX, which is based on the selector-side QoS measuring results. In ZX, we identify the QoS attributes which could be measured in selector's side, and provide possible solutions to gather the QoS information, and we introduce a new service selecting method, which concerns normal-the-better QoS attributes, by implementing the nearest neighbor algorithm.
Quality of service (QoS) is adopted widely in Web services research and practice for various purposes such as for metadata publishing and operational management of Web services. Nonetheless, current tools for monitoring and gathering QoS information support only a limited number of QoS attributes (e.g. response time, successful execution rate, availability) and therefore can neither well keep up to...
This paper presents a software application that can be used to secure existing web services, regardless of the language they were developed in and without any modification to the original source code. Thus, it can be used to expose internal services to external networks, in a secure way. Web service methods can be accessed based on the userpsilas rights. Furthermore, logging data can be maintained...
