14 September 2004
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
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
Networks for Non-Networkers
Early March 2005, NeSC
….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".
High Speed Cookbook: development using the information here and available from
MB-NG, DataTAG and elsewhere
UK Access Network
UK national R&D network infrastructure
Lancaster + DL
1. CDF : Connecting UCL - FNAL
1 Gbit/s sustained using new UDP protocol (UDT)
2. Radio Astronomy – eVLBI
eVLBI will connect up to 6 Telescope to JIVE in real-time for 2 years as a proof of concept
1. UK LIGHT Town Meeting
Organiser: Pete Clarke
Within the Programme:
Technology for High Performance Networks
Speaker, Robin Tasker
Live Demo of capability UCL-FNAL
Presenter: Nicola Pezzi
2. ESLEA: Exploitation of Switched Lightpaths for eScience Applications
Delivering the Potential of Optical Networking with UK Light
“The following applications can benefit immediately from UK Light:
HEP :Particle Physics Data transfer
VLBI: Radio Astronomy Very Long Baseline Interferometry
HPC: Computational steering and Visualisation
eHealth: Oncology Remote Visualisation”
Project Kick-Off Meeting : Thursday 16 September
Overview of Architecture Requirements
Requirements to be served
Teaching & Learning
IP production network
Flexible transmission platform
Reported at AHM, Nottingham. Presentation attracted ~50 people, diverse interest
See: http://www.allhands.org.uk/ for details, also on GridPP Web site
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.
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
