AGENDA • 8:00 AM:Welcome and Agenda review --- Shawn McKee (10 Minutes) • 8:15 AM:Optical Networking/Future Technologies --- Benoit Fleury (30 Minutes) • 8:50 AM:iVDGL/iGOC Operations Center --- Jim Williams (20 Minutes) • 9:15 AM:TCP Transfers over High-latency/bandwidth Networks --- Sylvain Ravot (20 minutes) • 9:35 AM:Open Discussions --- All (25 minutes) • End-to-end intitiative • Working with Astronomy on common network issues • Next Meeting location and agenda

3. Working with the E2E Initiative • HENP has been a “focus” group for the End-to-End Initiative • Many of our goals are focused on addressing pieces of this problem • We are currently exploring ways of working closely together to make some progress… • MonaLisa seems like a possible framework to house some of the needed monitoring/testing for E2E • Others interested in participating?

4. Joint Techs, February 1, 2003 HENP WG meeting Agenda • 9:00 Welcome/Agenda - Shawn McKee/Harvey Newman/Alberto Santoro • 9:10 Optiputer Applications - Tom DeFanti (20 minutes) • 9:30 Overview of HENP WG - Shawn McKee (15 minutes) • 9:45 HENP Activities - Harvey Newman (20 minutes) • 10:05 <Break> (10 minutes) • 10:15 FAST Protocol Overview - David Wei (20 minutes) • 10:25 Astronomy Overview - Eduardo S. Vera (15 minutes) • 10:40 VLBI and networks - Alan Whitney (20 minutes) • 11:00 Open discussion on networks, future technologies and common areas of focus between HENP and Astronomy We are exploring ways to work with Astronomy on networking issues of interest to us both

5. Next Meeting/Future Agenda? • We need to determine our next meeting date: • Joint Techs in August • Fall Meeting in Indianapolis • Possible “Joint” meeting with Astronomy at APAN meeting in Busan, Korea • Agenda Topics of Interest: • IPV6: Costs and Benefits, How to deploy? • End-to-end Monitoring/Diagnosis • Grids, QoS and Networks • Others?

6. HENP WG Goals • One of our first task upon forming our working group was to define a set of goals • These goals needed to address the range of interests and concerns of our community • We arrived at 9 goals, which are now part of our charter. • These are are the best definition of what our working group is about…

7. HENP WG Goal #1 • Support the development and deployment of toolkits, documentation and guidelines for best practices so that existing expert knowledge and tools for high throughput data transfers, packet loss and throughput-limit monitoring, and collaborative systems are widely known. Contact: Tom Hacker/Shawn McKee

8. HENP WG Goal #2 • Support the deployment of testing and monitoring tools and applications, link and site instrumentation, and a standard methodology, in association with the Internet2 End-to-End Initiative, so that all of HENP's major network paths can be adequately monitored, and used at full capability. Contact: Iosif Legrand

9. HENP WG Goal #3 • Share information and provide advice on the configuration of routers, switches, PCs and network interfaces, and network testing and problem resolution, to achieve high performance over local and wide area networks in production. Contact: Sylvain Ravot

10. HENP WG Goal #4 • Work with the staffs of the international (Tier0), national (Tier1), regional (Tier2) and local (Tier3) Grid facilities as needed, to verify high throughput and network responsiveness, in association with the Grid projects, and for new collaborative interactive systems. Contact: Les Cottrell

11. HENP WG Goal #5 • Work with the sites, expert networking teams at national labs, universities, and computational science centers, to develop and expand on a knowledge base for high performance networks. Develop a support base of knowledgeable engineers, technicians and scientists to assist with the above goals. Contact: <TBD>

12. HENP WG Goal #6 • Work to identify and track the programmatic network needs of the current and future generation HENP program: quantitatively in terms of bandwidths, throughputs and computer system capabilities required to provide the needed overall performance; and qualitatively in terms of the features and characteristics of existing and new systems needed for efficient distributed data access, processing and analysis as well as remote collaboration. Contact: Harvey Newman

13. HENP WG Goal #7 • Work with GriPhyN, PPDG, EU DataGrid, iVDGL and other Grid projects to ensure that the US and global network infrastructures are satisfying the programmatic needs of scientists using grids. Contact: Dantong Yu/Iosif Legrand

14. HENP WG Goal #8 • Work with the network engineering staffs of the US and global research networks to help define the requirements and operational procedures for a Global Grid Operations Center, and mission-specific Grid Operations Centers as needed, so that the ensemble of research networks is able to work efficiently and provide the high level of capability required. Contact: Jim Williams

15. HENP WG Goal #9 • Investigate emerging new network technologies, such as optical switching and lambda-based network infrastructure, for applicability and potential use in support of the HENP program. If appropriate, develop a strategic plan for coordinated deployment of these technologies among HENP sites. Contact: Phil Demar/Bill St. Arnaud
