StarPlaneOverview

• 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.

StarPlaneGoals

• 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).

BackgroundSURFnet6

• 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

BackgroundCPL

• 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.

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
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
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)

15
Future Plan

• Finish the WS development
• Research on the GMPLS simulation box in Canada
  via remote access
• Integrate AAA, DRAC...
