GridPP 11th Collaboration MeetingNetworking: Current Status Robin Tasker 14 September 2004
Network Objectives 1. To bring the technology of very high rate/long distance data transport to practical use in experimental production environments (both current and LHC experiments); and to demonstration of one or more UK HEP experiments being able to regularly transport data at rates in excess of 500 Mbit/s and preferably 1 Gbit/s. 2. To exploit the UKLIGHT infrastructure to utilise switched dedicated circuits between major centres including UK Tier1 and 2, CERN and FNAL. 3. To participate in EGEE oriented network monitoring service developments and deployment within the UK, and development of diagnostic engines for Grid operations 4. To maintain the strategic relation which HEP holds with all relevant major Network authorities globally. 5. To provide PPNCG support and other work as specified
High Performance Networking • The Details • Life of a Packet: Setting the scene. • Just What is OC-48?: Explanation of • networking terms • TCP Theory • TCP - Changes for High Speed Transmission • End-User Systems - NICs and Operating • System Kernel • Discs and Other Server Issues • LANs & Firewalls • Security Aspects • Diagnostic Steps in diagnosing performance • problems • An application Viewpoint: How do • applications view the network? http://grid.ucl.ac.uk/nfnn.html
High Performance Networking • Workshop Summary • Hosted by UCL • Organised by UCL / Daresbury Laboratory • Financial support from PPARC • 45 advance registrations • 2 attendees from the US including • Jenny Shopf from the Globus Team at • Argonne. • Delegates from a diversity of science • application areas, e-Science projects • and support roles. • Presenters from various UK institutions, • with European representation from CERN. • To be repeated at NeSC in March 2005 Coming Soon!!! Networks for Non-Networkers Early March 2005, NeSC Feedback ….a great deal of interest in the general themes addresses by the workshop: using an understanding of networking issues, common problems, diagnostics and fixes to "bring high performance to (your) applications".

Grid Network Monitoring http://gridmon.dl.ac.uk/gridmon/ Current partners: Current collaborators: Current status: Reported at AHM, Nottingham. Presentation attracted ~50 people, diverse interest See: http://www.allhands.org.uk/ for details, also on GridPP Web site
Grid Network Monitoring Activities 1. Tidying / consolidating existing infrastructure 2. Publication of performance data to Grid apps and middleware, via web/Grid services in conjunction with GGF NM-WG. Co-chaired by Mark Leese. http://www-didc.lbl.gov/NMWG/ Dealing with the What? Where? When? And How? Questions Goal is prototype operation using the UK Infrastructure by Christmas, but in close collaboration with EGEE JRA4, DANTE and UKERNA 3. Working in the GGF GHPN-RG, specifically in the thread net-services modelling the network as a Grid resource allowing “advance reservation” etc. 4. Developing a network Diagnostic Tool Starting consultation with GOCs (e.g. e-Science) and EGEE. Likely to involve collaboration (or at least liaison) with Internet2, and DANTE via EGEE
