WP 6 - High Bandwidth on Demand.

Work Package coordinator is Paul Boven (boven@jive.nl).

This Workpackage is a Service Activity in the area of Dynamic Circuits for radio astronomy, in particular real-time e-VLBI and LOFAR Long-Term Archive data.

The Workpackage consists of 4 tasks:

  • Task 1: Integration of e-VLBI with Bandwidth-on-Demand (JIVE, SURFnet, NORDUnet, OSO, CSIRO)
  • Task 2: On-demand access for large archives (ASTRON, SURFnet)
  • Task 3: Testing and validation of on-demand circuits (UMAN, JIVE)
  • Task 4: Multi Gbps on demand for e-VLBI (JIVE, SURFnet, NORDUnet, OSO)
