Deployment of IP multimedia services with guaranteed Quality of Service (QoS) is a primary requirement for Beyond 3G (B3G) systems. In this paper we propose a new architecture to support Internet QoS-sensitive services (e.g., video-conferencing, voice over IP, interactive gaming), thus providing users with end-to-end QoS guarantees. In particular, the paper discloses a new hybrid Intserv/Diffse...

The break of the 2 and the 3 century is in telecommunications characterised by an integration of various services that are provided by different networks into a single network. This trend is called service integration or network integration. Currently, this integration is not only focused on research work, but the solutions come to be implemented in practice as well. Service integration results...

Seamless end-to-end Internet Quality of Service (QoS) management is very challenging not only because Internet management is not well understood and practiced in the real world but because the nature of the Internet is hard to predict and manage. Secure transmission, transport reliability, ability to differentiate service qualities, QoS-based intelligent routing, QoS monitoring, and customerori...

The migration of the Internet from classic computer communication to a platform for multimedia applications with real-time communication requires end-to-end improvements of the network-level service. The proposal known as Differentiated Services is a very promising approach for implementing quality of service in the Internet and is being discussed and developed. The challenge is to deliver end-...

The paper presents a model for Quality of Service (QoS) signaling for complex multimedia services in the next generation network (NGN), from establishing necessary QoS support at session setup, to further QoS modifications in response to dynamic changes during the session. The model aims to maximize user perceived quality, while taking into account constraints imposed by the user, network, and ...

In an open and dynamic cloud computing environment, the randomness of cloud services with unreliable quality leads to low accuracy in service composition. To address the above problem, this paper proposes a global trust service composition approach based on random QoS and trust evaluation, considering the multi-criteria assessment of service quality. Firstly, statistical test is employed to rem...

Web services are becoming widespread nowadays. Determining the desired Web services is becoming an emergent and challenging research problem in many of the enterprise business applications. In this paper, we propose a Web service discovering approach which compares functional similarities to users’ queries, and nonfunctional QoS characteristics of Web services to obtain normalized result based ...

The successful integration of the Service Oriented Architecture (SOA) in large distributed environments greatly depends on their support of quality of service (QoS) management. The aim of QoS management is to guarantee diverse QoS levels to users issuing requests from a variety of platforms and underlying networks. In this paper, we present our policy-based framework for QoS management in SOA e...

FU, ZHI. Network Management and Intrusion Detection For Quality Of Network Services (Under the direction of Dr. S. Felix Wu) The explosive growth in worldwide communication via the Internet has increased the reliance of organizations and individuals on the electronically transmitted information, which consequently created rising demands to protect data from information leakage, corruption or al...

Business processes and their implementation as Web Service Compositions are not only dependent on Web Services and partners all over the Internet, but also on their failsafe execution. Service providers have to obligate their services to perform according to negotiated Quality of Service (QoS) parameters. For example, response time and throughput are important parameters to achieve fast and eff...
