3rd International IST-Anwire Workshop on Adaptable Service Provision
To be held in conjunction with the DAIS-FMOODS conferences 18 November 2003 - Paris
Invited presentations
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
Media Technology and Communication Networks - University of Lübeck
ISNM - International School of New Media GmbH
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.
Asst. Professor -- Head, High-Performance Computing Lab
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.
