The
TAPAS consortium brings together significant expertise from the
application hosting, distributed computing and middleware, fault
tolerance, software engineering, computer security and computer
networking communities.
All
the partners will take part and contribute to all the workpackages
and its tasks.Their principal responsibilities are described below.
The
coordinating contractor for TAPAS, the
Distributed Systems group conducts research on concepts, tools
and techniques for constructing distributed fault-tolerant systems
that make use of standard, commodity hardware and software components.
Current work is focused on dependable workflow management for
cross-organisation workflows, information sharing in virtual enterprise
and wide area group communication systems. The group has built
a number of major distributed software systems as CORBA middleware
services.
Newcastle
will lead WP2 and will play active role in the development of
the TAPAS architecture, tasks on QoS enabled group communication,
trust management, trusted coordination and auction application
development.
The
Principal Investigator at Newcastle is Prof.Santosh
Shrivastava.
Adesso
AG is a German mid-range company offering IT consulting, software
development and application hosting. Main clients are insurance
companies and banks, for which the company analyses, designs and
implements enterprise relevant applications based on component
technologies such as Enterprise JavaBeans. The variety of hosted
applications include applications in fields of telecommunication
(B2B) and Internet portals for online communities and banks. Hosting
of applications in areas of insurance companies and banks in mainly
performed by the clients themselves, though the requirements and
concepts are defined by the consultants and developers of Adesso
AG.
Adesso
will lead WP 4 and will provide case studies, hosting facilities
and undertake auction application development and evaluation work.
Adesso will also play an active role in WP1 by providing requirements
of application hosting.
The
Principal Investigator at Adesso AG is Werner Beckmann.
The
research group is currently investigating a number research issues
in the design of QoS-preserving, distributed middleware platforms.
Specifically, these issues include: i) strategies for providing
World Wide Web service users with adequate QoS. This activity
involves investigating the design of middleware services that
can meet effectively application-level (i.e., end-to-end) QoS
requirements of Internet-based, latency-sensitive multimedia applications;
and investigation on the use of group communication mechanisms
to support replication in database systems.
Bologna
will lead WP3 and will contribute to all the activities concerned
with QoS, in particular, QoS monitoring and QoS aware component
containers, as well as work on network control architecture and
auction development. Subcontractor of Bologna will be the Institute
for Information Science and Technology (ISTI), based in Pisa.
The key personnel of this Institute will provide Bologna and the
TAPAS project with highly qualified expertise on analysis and
evaluation of computer network architectures and protocols.
The
Principal Investigator at Bologna is Prof
Fabio Panzieri.
The
Software
Systems Engineering Group is concerned with the development
of large and complex software intensive systems. It focuses on:
the real-world goals for, services provided by, and constraints
on such systems; the precise specification of system structure
and behaviour, and the implementation of these specifications.
The three key technologies where the group contributes to the
state-of-the-art are: databases, distributed objects (particularly
middleware and mobile agent technologies), web infrastructure
(particularly XML and related technologies).
UCL
will lead WP1 and will contribute to the development of SLA specification
and analysis tool, architecture development, QoS aware containers
and evaluation.
The
Principal Investigator at UCL is Dr
Wolfgang Emmerich.
The
Systems
Research Group at the Computer Laboratory, University of Cambridge,
has been one of the premier research forces in communications,
distributed systems and operating systems since the founding of
the lab, the oldest computer science teaching department in the
world. Past projects include Universe (which delivered one of
the earliest high speed distributed systems), nemesis, a novel
operating system with excellent multimedia scheduling properties,
as well as Home Area Networks, Xenos (an accountable peer-to-peer
distributed architecture). Networks and Operating Systems related
work is focusing on Disk QoS Enforcing Quality of Service in Storage
Systems , Efficient Network Routeing, Next Generation Inter-AS
Routeing.
Cambridge
will concentrate on QoS networking requirements (WP1), Network
Control Architectures (WP2) and QoS enabled group communication
(WP3).
The
Principal Investigator at Cambridge is Prof
Jon Crowcroft.
