connect communicate collaborate 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 lots Dialogue 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.

Security policy exceptions only allow traffic from partners. DMZ hosts may use routed or P2P paths. Allows multiple projects.

connect communicate collaborate NETWORK MONITORING PERFSONAR 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: perfSONAR PS within I2/ESnet:

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:

connect communicate collaborate 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! 17
