GridPP 11th Collaboration MeetingNetworking: Current Status

Robin Tasker

14 September 2004

Gridpp 11 th collaboration meeting networking current status

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

  • 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


….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".

Early Adoptors

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

Grid network monitoring1
Grid Network Monitoring


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

via EGEE
