4. 06-06-06@UvA 4 StarPlane::Overview StarPlane is a NWO funded project carried out by UvA and VU with major contributions from SURFnet and NORTEL. StarPlane will use the physical infrastructure provided by SURFnet6 and the distributed supercomputer DAS-3. The vision is to allow part of the photonic network infrastructure of SURFnet6 to be manipulated by Grid applications to optimize the performance of specific e-Science applications. The novelty is to give flexibility directly to the applications by allowing them to choose the logical topology in real time, ultimately with subsecond lambda switching time.

5. 06-06-06@UvA 5 StarPlane::Goals fast, application-specific allocation of the network resources with deterministic characteristics; application-specific composition of the protocol stack that is used to control the resources; low-level resource partitioning (and, hence, no interference); high-level requests (whereby policies and inference are used to assist the user).

6. 06-06-06@UvA 6 Background::SURFnet6 In The Netherlands, SURFnet connects between 180: - universities; - academic hospitals; - most polytechnics; - research centers. with a user base of ~750K users It is a part of the world wide Internet. It is a hybrid network which offers not only regular Internet services but also lighpaths with speeds up to 10Gbps SURFnet6 was officially launched on 23-01-2006 ref: SURFnet

7. 06-06-06@UvA 7 Background::CPL Common Photonic Layer (CPL) is photonic portion for lightpaths: -6000km dark fiber network with Nortel DWDM and TDM equipments -5 rings -initially 36 lambdas (4x9) -later 72 lambdas (8x9) Each lambda with up to 10Gbps possible throughput

9. 06-06-06@UvA 9 Architecture I Control Plane Management Plane Connection from each site to: fixed OADM (Optical Add Drop Multiplexer) equipment and the WSS (Wavelength Selectable Switches) in the Amsterdam area.

10. 06-06-06@UvA 10 Architecture II Applications Network Elements Management Plane Control Plane web services job/workflow scheduler resource broker... resource description interfaces GMPLS / DRAC + AAA WSS, OADM, OME... Star Plane

11. 06-06-06@UvA 11 WSS WSS will allow us to redirect a selected input color to the output fiber This allows us to flexibly reconfigure the network according to the application demands. The key issue of StarPlane is subsecond switching, and topology reconfiguration.

12. 06-06-06@UvA 12 How to make it work develop the interfaces between the application and the management plane; describe all resources in a ‘common language’; investigate the capabilities of the various network devices related to StarPlane; manipulate the network devices in control plane on demand of application; integrate all possible solutions from different parties.

13. 06-06-06@UvA 13 Current Progress App use cases:  Large ‘stand-alone’ file transfers  Large file (speedier) Stage-in/Stage-out  App with static bandwidth requirements  App with dynamic bandwidth requirements WS prototype development Determine APIs for app (see next) Investigate HW

14. 06-06-06@UvA 14 APIs Examples:  query_availability(site_A_to_B, bw, s_time, diff_slot);  reservation(site_A_to_B, bw, s_time, duration);  free(res_id);
