THE GÉANT 100 GIGABIT ROLLOUT


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.


Day-1 connectivity used by MXs and extant routers (high level view)

CONNECTING THE CAMPUS &DATA TRANSFER END SYSTEMS


A Typical SiteAd Hoc Data Node Deployment

Eli Dart ESnet

Transfer node where user has space

Traffic subject to firewall &general campus LANs

perfSONAR at border

The goal is to provide:a high bandwidthloss free path to the data moving nodes.


Prototype Science DMZ

Eli Dart ESnet

Simple extension

Port on Border Router

perfSONAR at border & close to data transfer node

Campus firewall remains the same.

Security policy exceptions only allow traffic from partners.


Virtual Circuit Prototype Deployment

paths.13

Adding a P2P circuit

Direct or through Border Router

perfSONAR at border & close to data transfer node

Campus firewall remains the same.

Security policy exceptions only allow traffic from partners.

DMZ hosts may use routed or P2P paths.

Allows multiple projects.


NETWORK MONITORINGPERFSONAR MDM


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/


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!
