Grid Integration of Future Arrays of Broadband Radio-Telescopes Moving Toward E-VLBI

The purpose of this chapter is to present the design for the integration of radio-astronomical VLBI experiments with the Grid environment. The current status of VLBI process is described, and the main part of this document presents the proposed architecture for the development of the next-generation e-VLBI system, together with the analysis of potential problems and design limitations. This design was done for the purpose of the EXPReS project [5], partially funded by the European Commission (FP6–IST). It was created with significant help and close cooperation from the Joint Institute of VLBI in Europe (JIVE) [10].
