The National Centre for Scientific Research (NCSR) DEMOKRITOS is the biggest
research centre in applied sciences and engineering in Greece and it is a self-governing
research organisation, under the supervision of the Greek Government. NCSRD
consists of eight Institutes spanning a broad range of activities, and of divisions
responsible for administrative and technical support. Staff sums up to about 800 persons. It is the
home of the Greek National Host and a major node in the Greek National Research and Technology
Network (GR-Net). NCSRD participates in the project through the Institute of Informatics and
Telecommunications (IIT) that comprises 15 senior researchers, 6 postdoctoral fellows and 12 Phd
Students. IIT has a leading experience in the telecommunication and
informatics areas relevant for the project such as Next Generation, media-oriented network
architectures based on technology convergence, IP Multimedia Subsystem (IMS) and IMS-based
management of multimedia services, Real-time network adaptation and dynamic resource allocation
for multimedia provisioning, Virtual Private Network and Network Security over Heterogeneous
Networks, Virtualisation Environments Secure Networking. The following are some of latest EUfunded
competitive research and development projects, in the area of Telecommunications, in
which the Institute of Informatics and Telecommunications has participated: LIAISONFP6/
IST(IP), ENTHRONE-I and II-FP6/IST(IP), ATHENA-FP6/IST, IMOSAN-FP6/IST, UNITEIST/
FP6, ADAMANTIUM-ICT/FP7, HURRICANE-ICT/FP7, ALICANTE-ICT/FP7(IP) and
PERSEUS-SEC/FP7(DEMONSTRATION).
Role in the project. In GERYON, NCSRD will undertake the leadership of WP3 and will coordinate the design and development of GEMS. In addition to participating to the system definition/specification phase, NCSRD will focus on the implementation of the TAMS and its submodules (RCM, TMM, SMM, ESMM) on an existing experimental IMS platform. NCSRD will also contribute to the implementation of GEMS Media and Security Gateways and will actively participate in the integration and trials phase.
