Service Adaptation: issues and visions

Dr Antonio Liotta, Lecturer,
University of Surrey, Centre for Communication Systems Research

Service adaptation in the context of 3G and beyond has gradually gained interest alongside the development of the necessary baseline technologies. The OSA/Parlay specification addresses the need for a unified service architecture towards the realisation of the important concept of service-centric network. We are also witnessing dramatic evolutions in the business context that seems to have matured only now what TINA was already envisioning in the 90s: the need to decouple service providers-related roles from the network operator role. This need arises from a combination of factors which originate in the general believe that the best way to increase future ICT-related revenues is through new, advanced services. These have the potential to appeal customers, on the one hand, and increase traffic, on the other one, generating new revenues for service, content, and network providers. The ultimate killer service has, however, still to be invented, so many are looking at adaptable, context-aware, context-driven, personalised services as a "revenue-buster" vehicle. The talk will address some burning issues related to the lifecycle of adaptable services, looking at new means for scalable service deployment.

Media Adaptation for Ubiquitous Computing

Prof. Dr.-Ing. Andreas Schrader

In future ubiquitous computing environments, the heterogeneity of existing networks, applications, services and user profiles will increase even further. More sophisticated methods for adaptation of real-time and non-realtime media will be necessary. Although the pervasive embedding of computation power into everyday objects will enable completely new multimedia scenarios, it is actually unclear, how this kind of distributed - somehow chaotic and often adhoc established networks using very limited device capabilties can support media. The talk presents a survey on some of the current technologies for media adaptation in the Internet, present some results on video adaptation and outline necessary future steps.

Intermediaries for the WWW: Survey and Classification

Marios D. Dikaiakos, Ph.D.

Dept. of Computer Science -- University of Cyprus   

Intermediaries  are  software  entities,  deployed  on  hosts  of  the  wireline  and  wireless  network,  that mediate the  interaction  between  clients and servers of the  World-Wide Web.  In this talk we present  a survey of intermediaries,  focusing on systems beyond simple caching  proxies.   We  classify  different  intermediary  systems  into  three  categories,  based  on  their   functionality  and  focus:  First,  we  investigate notification intermediaries,  which are driven by end-user  profiles  and operate  even  in the  absence  of end-user  connection.  Then,   we  study   intermediaries  developed   to   support  wireless  connectivity,   mobility,   and   ubiquity.    Finally,   we   examine  intermediary  infrastructures designed  to extend  the support  of the  core  network for  the  development and  deployment  of new  services.  Based on this survey, we propose a detailed taxonomy of intermediaries  and  identify key features  of emerging  intermediary infrastructures.  Taking  into  account  recent  advances  and trends  in  wireless  and  pervasive  Internet  technologies, we  present  a  number of  research  challenges,  which  need  to   be  addressed  in  order  to  integrate  intermediary systems in next-generation Internet infrastructures.  

Adaptable service provision over reconfigurable mobile networks

Nikos Houssos, Research Associate
Communications Networks Laboratory, Dept. of Informatics and Telecommunications,
University of Athens

The significance of adaptation in next generation mobile systems and services is widely recognized. Adaptation capabilities form a principal enabler of ubiquitous, seamless service provision over highly diverse, reconfigurable underlying infrastructures. Although many research efforts have already focused on various aspects of adaptability, there is a lack of systematic methods for tackling the respective technical issues. This talk introduces a framework and principles for the engineering of adaptation functionality in mobile systems and services. Futhermore, it identifies critical research problems and presents an overview of potential solutions that are based on a mediating service provision middleware architecture.
