BT Organisation Structure Qualifying team……… Process is ongoing and parallel with…. Proposal Team Workpackage Owner - Ron McArthur, Workpackage Manager - Shobo Leung, Relationship Manager - Lea Brothwick, Legal & Regulatory - John Ward Network Solution Design Network Construction Network Plan and Build

Our research capabilities…. Committed to research in advanced communications We have over 3500 people engaged Adastral Park Commercial Research Centre BT, and Fujitsu, Alcatel, Pirelli, Seimens, Corning, UCL, CMI, Xeros, MMO2 and Marconi with over 4000 researchers on site Optical Labs, IP, Advanced Communications Labs, RF Research Labs, Materials…. Strategic consulting internal and external Technical Consulting internal and external Evaluation of telecommunications equipment Network Acceptance Testing - certification Software Development Trial of new Services and Facilities Demonstration Brightstar Research incubator - transfer research into commercial market place

What is required... Instruments Optical connected VLBI Financial models should include telecommunications requirements Co-ordination of telecommunications activities - an agreed view and timing Generic network component(s) - building blocks Service rap for Astronomy Research e.g. Real-time VLBI etc Standards : Use International VSI-H R&D Transport protocols - 1GE, 10GE, 10G/40G/160G Statement(s) Network Of Requirement (SNOR) - Locations, Bandwidths, Service Communications Solution Design Co-ordination Funding activities Consortium of suppliers and partners Implementation plan Instruments Construction of New Infrastructures - upgrade Design Studies - Technical preparatory - evolution to 10GE, 40G, 120G, 160G IST Integrated Projects - possible new workpackage Advanced Optical Networking proposal

Network Requirements ... Capacity Dependent Array Interface Elements Scientific instruments integrated at optical transport layer Network Configuration : Star Routing : Single Path (no path protection) Route Protection : manual Network Management Centre Alarm Management The data flow is one way - telescope to Correlaters Data Protocol - VSI-H (others ?) Transport: jitter free Interfaces : 1GEathernet and 10G Lambda (transparent) Evolution - 10GEathernet, 40G, 120G, 160G Interface protection (N to 1, manual switch) Seamless interconnection with existing research Networks New build for ‘last mile’, ‘middle mile’ new fibre (DWDM) Affordability Array Interface Elements Capacity Evolution Dependent eMERLIN 3 x 10G 7 210 Gbps 40G eEVN 1 x 1GEnet 16 30 Gbps 10G New Correlater LOFAR 40G or 160G Sites 1 Tbps 20 Tbps SKA Global VLBI 1 x 1GEnet Upto 50 100 Gbps 10G ALMA 10G or 40G 64

Questions …. Will there be an element of ‘Public Understanding of Science’ Also, ‘Public Engagement in Science’ Linkage with Educational Initiatives
