starplane overview
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.
starplane goals
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).
background surfnet6
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

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

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.
how to make it work
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.
current progress
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
slide14
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);
future plan
Future Plan
  • Finish the WS development
  • Research on the GMPLS simulation box in Canada via remote access
  • Integrate AAA, DRAC...
