NEXPReS WP6 - High Bandwidth on Demand
Paul Boven ([email protected]) - WP6 Activity Leader
• 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)

NEXPReS WP6 - High Bandwidth on Demand
Future activities (?)
• Implement NSI v2.0 in the NEXPReS client
• Topology, Pathfinding, A&A
• Integration with network (observatories & JIVE)
• Higher bandwidth observations (4 Gb/s)
• GÉANT GN3+ Open Call
• Proposal for Topic 3 (Novel uses of Dynamic Circuits)
• OSO, SURFnet, JIVE
• If accepted, starts October 2013

Current and Future Requirements



eVLBI is preferred to disk based observations (real time results,
fault diagnosis at stations, ToO experiments, etc)
Higher data rates allow increased sensitivity observations - new
science
Digitized data provided by:
Time


Analogue back end:

Mark 4/VLBA formatter - 1024 Mbps

VSI-H - > 4096 Mbps
Digital back end:

dBBC + FILA 10G, RDBE & others – 10 Gbps
Third NEXPReS EVN-NREN meeting – Tuesday, 25th June 2013

RI-261525
Current and Future Requirements
Mark 5 recorders – standard for VLBI and Geodesy

Current:
Time



Mark 5A: data rates ~ 1024 Mbps to disk or network

Mark 5B: data rates ~ 2048 Mbps to disk, > to network

Mark 5C: data rates ~ 4096 Mbps to disk, > to network
New (available as of 2013-06-21):

Mark 6: data rates ~ 16 Gbps continuous to disk or network (31 Gbps
burst)
Third NEXPReS EVN-NREN meeting – Tuesday, 25th June 2013
RI-261525
Current and Future Requirements

Mark 5A/B hardware now obsolete (i.e. new units no longer
available to purchase)

Mark 5C/6 hardware current

Mark 5* support until September 2015

Users urged to upgrade

June 2012, 3 station (Efflesburg, Onsala, Yebes) eVLBI at 4 Gbps

Future – more stations, more bandwidth

In summary
The GÉANT backbone upgrade is nearly complete offering:
“More for all”
– more bandwidth at our disposal
– more flexibility – versatile & rapid service provisioning
– more function – leading to more service offerings
– more accessibility to GÉANT users
Real Future Proofing … towards the Horizon (2020)
The GÉANT MX approach to the 100G multi-domain challenge:
BoD service available in every PoP
NSI v2.0 availability
– alpha July 2013
– beta in September 2013
OpenFlow on MXcould be a powerful API for configuring the
L2 data plane
