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.
