GRNET intends to contribute mainly to the eInfrastructure Work Package. GRNET as the National Research and Education Network of Greece, and its participation in the GEANT, SEEREN and Eumedconnect projects, has gained the necessary experience and knowledge including the necessary contact persons and conditions in the region, in order to conduct the related work. GRNET will mainly focus on providing support in the deployment of e-Infrastructure tools and services, such as video-conferencing and AccessGrid virtual collaboration environment. In addition, through its participation in European and regional related Grid projects such as EGEE, SEEGRID, EUMEDGRID and EuChinaGrid, GRNET can also provide links with the Grid ecosystem, with both peer European and regional entities, as well as HPC communities and research groups. GRNET has well qestablished teams and mechanisms for delivering Grid training, supporting the application porting in the Grid, as well as installing and operating Grid infrastructure. In the last year of the project, GRNET will make an effort to transfer some of the above experience and knowledge to the ITHANET communities, with the help of other ITHANET partners, such as CESNET. In particular, training events will be organised in Cyprus or other areas of interest, and an effort to investigate the feasibility of porting ITHANET application into the Grid will be made as follows: With regards to collaboration with other projects, GRNET can link Ithanet with European or regional projects doing similar work in both the networking and grid area. On the networking environment GRNET can link the Ithanet partners with the Eumedconnect and GEANT projects, that have worked in the past or offering related video-conferencing services. A cookbook on different video conferencing options would be proposed. In addition, an effort to transfer the experience from the TERENA Task Forces on real-time services will be made also. On the grid environment GRNET can link with pan-European and regional efforts such as EGEE, SEE-GRID, EUMEDGRID and EUCHINAGRID, that are undertaking porting and adaptation of similar applications. Similarities with the ITHANET environment and communities needs will be investigated, so that economies of scales and reuse of existing software can be the case. In addition, experienced teams will be consulted on the above issues. Finally Grid induction and more advanced training such as training on application porting will be investigating, after evaluating the maturity of the related communities.
