Why was the GNT needed?

The Grid Networking Team (GNT) plays a crucial role in supporting e-Science and grid applications by providing essential end-to-end networking expertise. The GNT, led by experienced members from various universities and organizations, assists grid projects in identifying their communication requirements and advising on key networking developments. Collaborating with major bodies such as JISC and GGF, the GNT facilitates the integration of campus networks, metropolitan area networks, and core facilities to enhance the technology and infrastructure necessary for advanced research and collaboration.

Presentation Transcript

  1. Why was the GNT needed? • End-to-end networking essential for e-Science & Grid applications • UKERNA / SuperJANET provides a core facility to users • MANs, campus networks (and end-systems) complete the end-to-end picture • Technical and organisational assistance with networking evidently needed by Grid users David Hutchison, February 2003

  2. What has the GNT been doing? • Source of networking expertise for Grid projects: Demonstrators, Testbed applications, Grid Centres activities, international projects etc. • helping projects specify end-to-end communications requirements and advise on networking developments • Liaison with bodies including the JISC Committee for Networking (JCN), Global Grid Forum (GGF), National Research Networks (NRNs), DANTE, … • Advising the Director e-Science Core Programme about any networking issues that arise David Hutchison, February 2003

  3. Who are the GNT members? • David Hutchison (Lancaster Univ., chair) • Peter Clarke (UCL, vice chair) • Chris Cooper (OBU/UKERNA) • Jon Crowcroft (Cambridge Univ.) • Bob Day / Jeremy Sharp (UKERNA) • Roland Rosner (Computer Centre, UCL) • Paul Jeffreys (Oxford Univ. Comp. Services) • David Williams (Networking Division, CERN) • Tim Chown (Comp./EE, Southampton Univ.) • Robin Tasker (CLRC, Daresbury Lab.) • Scott Currie (Edinburgh University) • David Salmon (UKERNA, secretary) • Jim Fleming (for EPSRC) • Ray Browne (for DTI) • [David Boyd (CLRC, RAL); • [Mike Daw (Manchester Univ.)] David Hutchison, February 2003

  4. How has the GNT operated? • The GNT members have met 4-6 times a year and at other times as necessary, to set policy etc. • The core group consisting of David Hutchison, Peter Clarke, Chris Cooper and David Salmon have met and/or conferred on an as-needed basis • The operations staff based at UKERNA have been set up to provide technical and strategic support • The monitoring group based at Daresbury Lab have initiated Grid monitoring for Centres and projects David Hutchison, February 2003

  5. Grid Network Team National & Regional GridCentres GNT technical support eScience support centre Grid projects & users e-Science Dir ; JISC / JCN ; UKERNA / NOSC University Computer Centres and MANs What links does the GNT have? David Hutchison, February 2003

  6. What basic questions do we ask? • Does the project stretch the Grid, with today’s networks? • What sort of support would be required from the GNT? • Is this potentially related to other projects or Grid activities? • Does the project have specific challenges or other interests? • What are the future requirements likely to be? David Hutchison, February 2003
