2. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org Applications controlling networks Research efforts around the world: UCLP, AutoBahn, DRAGON, G-Lambda, Enlightened Research efforts in the Netherlands: SURFnet and CPL, EnlightenYourResearch and … StarPlane When do applications need this level of control? - Research involves very large datasets - Data needs to be transported securely - No hick-ups in the connection allowed - Remote collaborations - Access to distributed resources - Use of HD-video or high quality media (4k digital cinema) e-Science applications need more control over the network

3. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org Lightpaths Lightpaths provide the best service Two approaches to delivery of lightpaths: -Static: ‘Here is your path, bye.’ -Dynamic: ‘Tell me when you need it, tell me when you are done’ Two approaches to control of the paths characteristics: -Provider controlled: ‘Tell me what you need’. -User/application controlled: ‘Do-it-yourself’ Lightpaths are: - Dedicated connection in the network; - Guaranteed QoS: jitter, delay and bandwidth; - Use optical/photonic equipment: lambdas

4. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org The StarPlane project StarPlane is an NWO-funded project. UvA and VU (Vrije Universiteit) perform the research together, in close cooperation with SURFnet and Nortel Networks. Dynamic and application controlled lightpaths Five DAS-3 clusters communicate over the WAN using controllable lightpaths in a portion of SURFnet6.

Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org CPL and WSS CPL- Common Photonic Layer - dark fiber network (6000Km) with Nortel DWDM and TDM equipment; - DAS3 sites connected on one ring. WSS- Wavelength-Selective Switches - allow to redirect a selected input color to a selected output fiber; - goal is sub-second switching, and topology reconfiguration.

10. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org First applications: SCARIe eVBLI: correlation of astronomical data. Lightpaths transport data from telescopes to correlation centers. Software correlation: dividing the incoming data into small chunks of data that are correlated independently. SCARIe over StarPlane: dynamic photonic lightpath switching is an efficient solution to distribute datasets for network intensive tasks.

11. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org First applications: AWARI AWARI: a distributed game-tree search. Performance on distributed cluster approaches that of a single large cluster. Slide material courtesy of Kees Verstoep

12. Session 9A, 25 October 2007 eChallenges e-2007 Copyright 2007 StarPlane: www.starplane.org Conclusions First results: -First batch of applications making use of the StarPlane network. -Starting to test the integration of the management plane and the control plane (SPMP and DRAC). Work ahead: -Involve more applications; -International links and expanding infrastructures, Grid5k in France.
