High Energy and Nuclear Physics SIG Meeting
Fall 2004 Internet2 Member Meeting

The Internet2 High Energy and Nuclear Physics (HENP) Special Interest Group (SIG) met on 28 September 2004 at the Fall 2004 Internet2 Member Meeting. This session focused on future networking issues, especially related to 10 Gigabit networks and beyond.  The agenda featured reports on ESNet, UltraLight, FASTTCP, 10GB transfers, E2E efforts and information about other ongoing activities relevant to HENP.

Dial-In Participants, See Connection Info Below.

Agenda

HENP, E2E and Other Activities [PPT] — Shawn McKee, University of Michigan, smckee@umich.edu

10GbE WAN Data Transfers for Science [PPT] — Yang Xia, Caltech, yxia@caltech.edu

The adoption of 10GE network is now widespread; the benefits are compelling and the supporting technologies are mature.  This presentation will explore some of the important technical issues to successfully and efficiently transfer data on the 10GE WAN with Linux and Windows for demanding projects such as LHC.  The talk will discuss these topics:

• Introduction
• 10GE NIC comparisons & contrasts
• 10GE WAN performance from A to Z, including
  • Interoperability
  • benchmarks
  • diagnostic tools
  • network architecture and tuning
  • new network features in Linux 2.6.x kernels

ESNet, Status and Plans [PPT] — William E Johnston, ESnet/LBNL, wejohnston@lbl.gov

ESnet is driven by the requirements of the science Program Offices in DOE's Office of Science (OSC). ESnet currently provides a high-bandwidth core network ring around the country, with hubs at strategic locations. Forty-two sites are connected to the hubs, and the OSC Labs typically connect at 0.6 or 2.5 Gb/s. However the findings of two workshops that systematically examined OSC science requirements, as they relate to networking and middleware, have established some new strategic directions for ESnet in order to meet the OSC networking needs in the next 5-10 years. A new architecture extends the reliable ring concept to connecting sites and a second core network (the Science Data Network) is devoted to large-scale data movement.

FAST TCP: Recent Experiments [PPT] — Steven Low, Caltech, slow@caltech.edu

We investigate the effectiveness of FAST TCP in several high-speed network infrastructures.  We also report on new developments that address some performance issues, such as burstiness control, reverse path congestion, and briefly summarize some theoretical results.

UltraLight: A Preview [PPT] — Shawn McKee
