The GÉANT Procurement
Started at the beginning of 2010 with an RFI exercise (6 months)Formal Competitive Dialogue procurement process at the end of 2010 in 3 lotsDialogue ran throughout 2011, resulted in ITT for:
Technology agnostic approach to transmission“100G-optimised” transmission with flexible deployment of 10G services [lot 1]“Classical IP/MPLS” for “Packet transport” solutions for the switching layer [lot 2](Alternatives (MPLS-TP, PBB-TE) did not look sufficiently convincing)
We selected:DTN-X solution from Infinera Juniper MX IP/MPLS switch/routers
In addition we have re-procured the dark fibres.

NETWORK MONITORINGPERFSONAR MDM
connect • communicate • collaborate
Collaboration + brilliant performances: perfSONAR – effective monitoring
Effective operations require proper network troubleshooting at an international scale
perfSONAR gathers information from different network domains and builds a global picture
Each measurement point runs perfSONAR software to measure the following metrics:
Available Bandwidth
One Way Delay
Jitter (One Way Delay variation)
Route Tracing
Regular historical & ad hoc on demand measurements.
Implementations interoperate, OGF standard:
perfSONAR MDM within GÉANT: http://perfsonar.geant.net
perfSONAR PS within I2/ESnet: http://psps.perfsonar.net/
connect • communicate • collaborate
A new perfSONAR MDM:Compatible, open, interoperable
Developers actively working with the user community
Using direct user feedback to keep meeting their expectations
perfSONAR User Panel to gather requirements and steer development
Simplified installation procedure
RPMs and DEB packages available
Pre-installed, ready to use, Virtual Machines available
perfSONAR-take-away – live distribution on a USB stick
Revised documentation (lightweight and modular)
Interoperable with perfSONAR-PS
Successful use-cases: http://bit.ly/pdJJlf, http://bit.ly/pc5sZO,

Summary
With European and world collaborations, the network is an integral part of the science and research.
Many connectivity service options are available to match the project requirements: Routed IP, pt-2-pt circuits, Lambdas, BoD.
The upgrade of the GÉANT infrastructure will to move it towards Terabits – plenty of Bandwidth available & more flexibility.
Involving the campus and NREN network teams in the e-infrastructure projects is a big plus.
Design the connectivity to the high performance nodes to avoid campus bottlenecks – e.g. the DMZ approach.
Make debugging easy by provide on-campus perfSONAR MDM network monitoring.
Provide a budget line item in the project for network connectivity.
Don’t forget to get the remote end to contact their NREN too!
