ESnet On-Demand Secure Circuits and Advance
Reservation System (OSCARS)

• Testing and Deployment Status (1/2)
• Circuit Testing Between BNL and FNAL (4Q04, 1Q05)
• Bidirectional circuit between BNL and FNAL (at
  Starlight).
• Initial LSP was configured for 50mb/s and
  subsequently increased to 400mb/s.
• FNAL used lambdaStation (www.lambdastation.org)
  to drop return traffic at Starlight.
• UDP tests succeeded in showing containment of
  reserved bandwidth.
• TCP tests yielded poor results due to unshaped
  traffic being policed.
• Circuit Testing Between GA and NERSC (1Q05)
• We were successful in running a real application
  test using the MDSPlus data management and
  acquisition system.
• With contending traffic, MDSPlus transfer was
  3.2mb/s without an OSCARS circuit, and 23mb/s
  with an OSCARS circuit.
• MDSPlus application ran without any alteration
  (e.g. no changing of DSCP bits, etc.).
• NB Maximum MDSPlus data transfer of 23mb/s was
  limited due to application implementation.

• Testing and Deployment Status (2/2)
• First Production Use of OSCARS Circuits (2Q05)
• OSCARS functionality was pressed into service
  when the production LHC 10GE connectivity between
  FNAL and CERN was disrupted due to a fishing boat
  severing CERNs link to Chicago.
• As a result of the cut link, LHC Service
  Challenge data was rerouted over FNALs
  production OC12 (622mb/s) causing severe
  congestion.
• As a temporary measure, an OSCARS circuit
  carrying only LHC traffic was configured between
  32AoA (in New York) and Starlight (in Chicago).
  This caused the LHC traffic to traverse FNALs
  non-production connection at Starlight,
  offloading the production OC12.
• Yet More Testing
• The scheduler and authentication modules are
  currently undergoing more tests and refinements.
• End user beta testing is expected to start 3Q05.

• Collaborative Efforts
• Collaboration with Internet2 (2Q05)
• ESnet hosted a 2-day working meeting with
  Internet2s Bandwidth Reservation for User Work
  (BRUW) project.
• A decision to jointly develop code for OSCARS and
  BRUW was agreed upon. This is possible because
  OSCARS and BRUW have very similar architectures.
  We have adopted their WBUI, but are rewriting a
  substantial portion of the back-end. They are
  interested in using our PSS and potentially the
  BSS. Joint development of the AAAS may be
  complicated by different security requirements.
• Dynamic setup of an inter-domain LSP circuit
  (between ESnet and Internet2) is targeted for the
  SC05 timeframe. A motivation for this would be
  to accommodate LHC T1-T2 data transfers.
