Despite the tremendous
growth in terms of users, applications and protocols that the Internet has
experienced since its inception three decades ago, its basic design has
remained intact, namely of providing basic best effort unicast delivery of
packets. On the other hand, there is a growing demand for sophisticated
services by a rapidly growing, diverse in outlook user population that
requires more advanced network architectures, system design and
protocols. The purpose of the
workshop was to provide a forum for discussion and exchange of ideas
regarding service-oriented networks and computing that requires modular,
distributed and re-configurable capabilities, and blends network and
service functions in order to enhance end-user and business
functionality. The workshop includes 14
oral presentations that cover diverse topics, including pricing, dynamic
resource allocation, architecture, workload models, and
security. The presentations are organized in regular
sessions, consisting of full-size, peer-reviewed articles, and “hot topic”
sessions. Specifically, Haddad and
Viniotis examine 3-tier service level agreements for network applications
that require quality-of-service guarantees and introduce an automatic
class upgrade mechanism when unused bandwidth becomes available.
Kallitsis, Michailidis and Devetsikiotis study optimal resource allocation
for a network node supporting advanced services subject to
quality-of-service constraints. The proposed allocation mechanism is based
on maximizing the node operator’s utility function and incorporates an
online traffic monitoring scheme. Zhu and Pavel study pricing designs for
a power control game in optical networks through a state-space modeling
framework. Batista and de Fonseca survey resource allocation mechanisms in
service oriented grids, examine their relative merits and discuss future
research directions. Three papers address
network architecture issues. Specifically, Ooms et al. propose
architectures for delivering authentication, authorization and accounting
to multi-domain services, while Wu et al. introduce a network architecture
capable of coordinating the management tasks amongst network providers,
service providers and end users. Brown, Kolberg and Buford discuss an
adaptable overlay structure for wide area network service
discovery. The characterization and synthesis of
Markovian workload models is the focus of Casale, Zhang and
Smirni. The hot topics
contributions cover a wide range of topics, including availability and
reliability issues for service oriented networks by Rigler and an overview
of security issues associated with large scale networks by Meyr,
Tschofenig and Karagiannis; a proposal of a framework for experimental
screening, control and optimization of network architectures and protocols
by Sirotiuk; a survey on the cross-layer paradigm for the next generation
Internet by Granelli; middleware challenges in next generation networks by
Kormentzas and Skianis, and service-oriented networking architectures by
Callaway and Rodriguez. |
