UDP testing by Dantong Yu (dtyu@bnl.gov) demonstrated that the full 400mb/s was attainable, and that packets in excess of the 400mb/s were dropped (as designed). Configured LSP for testing between GA and NERSC ----------------------------------------------- A pair of bi-directional LSPs were setup between GA and NERSC to test wide-area QoS. One LSP was given best effort service, and the other guaranteed service. The traffic injected into either LSP was based on source-destination host-pair filtering. A summary of the test setup and results are below: GA test host 'EOS' was GigE connected, and generated best effort service traffic. GA test host 'GEMINI" was FastE connected, and generated guaranteed service traffic. NERSC test host was GE connected, and used as a sink for test traffic. Bottleneck was an OC3 (155mb/s minus overhead). Iperf was used as the testing application. All UDP test streams was limited to 100mb/s using Iperf parameters. - Single Non-Competing UDP streams 100mb/s UDP stream from EOS resulted in 98.4 mb/s 100mb/s UDP stream from GEMINI resulted in 95.3 mb/s - Single Non-Competing TCP streams TCP stream from EOS resulted in 47.1 mb/s TCP stream from GEMINI resulted in 76.8 mb/s - Concurrent Competing UDP streams 100mb/s UDP stream from EOS resulted in 48.5 mb/s 100mb/s UDP stream from GEMINI resulted in 95.7 mb/s - Concurrent Competing TCP streams TCP stream from EOS resulted in 31.2 mb/s TCP stream from GEMINI resulted in 76.5 mb/s - Concurrent Competing UDP/TCP streams 100mb/s UDP stream from EOS resulted in 66.2 mb/s TCP stream from GEMINI resulted in 76.1 mb/s As seen from the test results above, the traffic in the guaranteed service LSP (from GEMINI) was unaffected by competing traffic in the best effort service LSP (from EOS). With the above tests completed, GA has started testing with real data from the MDSPlus server in GA to a client at NERSC. NERSC's participation --------------------- The tests between GA and NERSC was made possible by the significant involvement of Eli Dart (dart@nersc.gov) from NERSC. His participation included locating a test host, identifying the traffic path within NERSC's LAN, and making the necessary configurations on routers and switches to accommodate the tests without impacting production traffic. He also assisted GA in identifying an appropriate test host and provided technical assistance in setting up the appropriate test suite and TCP tuning parameters. NERSC's role in OSCARS is to develop and test LAN architectures to provide QoS for traffic flows that will utilize the LSPs provided by OSCARS. With the ESnet Bay Area MAN coming on-line within the next few months, NERSC is an excellent choice to test high bandwidth guaranteed circuits and potentially be an early adopter of the service. Presentation and BOF at Internet2's Joint Tech Meeting in Salt Lake City ------------------------------------------------------------------------ A presentation of the OSCARS project was given at Internet2's Joint Tech meeting in Salt Lake City in mid-February. In addition to the presentation, a BOF was hosted by ESnet to discuss technical issues relating to reservable guaranteed bandwidth services. This opened discussions with other like-minded projects, notably Internet2's "Bandwidth Reservation for User Work" (BRUW), and GEANT's "Bandwidth on Demand" (GN2-JRA3) projects. Collaboration with Internet2's BRUW project ------------------------------------------ Resulting from the BOF at Internet2's Joint Tech meeting, ESnet and Internet2 have agreed to share design and implementation details, including code sets, so as to better facilitate interoperability. Goals for next quarter ---------------------- - Bring on-line Reservation Manager with simple authentication. - Allow user to create a bandwidth circuit reservation via a web-page. - Dynamically setup and teardown the circuit. ----------------------------------------------------------------------------
