Network Connections – e-VLBI Tasso Tzioumis ATNF Basic Network • • • • • • 2 dark fibres from NextGen network AARNet3 regional network CSIRO + Universities – Gigabit connections “Production” network (~1 Gb/s) “Research” Network (~10 Gb/s) x ? CSIRO ITS Business Case – ATNF inputs – Submitted 13 May 2004 31/5/2004 A. Tzioumis 2 The NextGen Network 31/5/2004 A. Tzioumis 3 Network “Lighting up” • • • • Dark Fibres (only 2 lit-up commercially) Need equipment every 80 Km $8-10M to light Base network ”Australia Research & Education Network” (AREN) funding? – $5M • AARNet management of connections • Replace current phone/data links 31/5/2004 A. Tzioumis 4 Network speeds & costs • Coarse Wave Division Multiplex (CWDM) – 8 x 1 Gb/s – Relatively inexpensive – Lifecycle 3-4 years – CSIRO $1-1.5M + $150-350k/year • Dense Wave Division Multiplex (DWDM) – 80 x 10 Gb/s (or 40 Gb/s) – CSIRO $1.7-2.5M + $300-500k/year – Lifecycle >10 years 31/5/2004 A. Tzioumis 5 “Last mile” connections • Need network “tail-end” connections to each site • Expensive BUT included in budgets • AARNet will manage project • Sites provide “air-conditioned” rack • ATNF sites surveyed and costed (NDC) • Connection Maps 31/5/2004 A. Tzioumis 6 Parkes Connections 31/5/2004 A. Tzioumis 7 Mopra Connections 31/5/2004 A. Tzioumis 8 Narrabri Connections 31/5/2004 A. Tzioumis 9 Production Network ANU, Siding Springs ATNF Mopra (Coonabarab ran) ATNF Narrabri Cotton Research Narrabri ATNF Parkes AARNet Regional Network Sydney Access Node, UTS 10 Research Network ATNF Narrabri ATNF Mopra ATNF Parkes ATNF Epping SX Transport Tidbinbilla This Project Swinburne Univ Ceduna Mt Pleasant, Tas Related (future) Projects 11 Tail Link Costs • Production net - $900k-1.4M – +$40k per extra link • Research DWDM network • 10 Gb/s links – $72k for link <600 Km (Mopra, Parkes) – $144k for link >600 Km (Epping) • Tidbinbilla “in scope” – Link with ICON network – Up to $400k? – ANU/Stromlo connections 31/5/2004 A. Tzioumis 12 Related & Future links • Mt. Pleasant observatory – LIEF proposal • Ceduna Radio telescope – Long distance (200km) to NextGen – Telstra? • Swinburne – Capital cities network – Traffic? • NTD pathfinder in WA ? – New Norcia? • Overseas – Japan, USA 31/5/2004 A. Tzioumis 13 Key Milestones Event/Milestone Deliverable Date AARNet secures AREN Agreement with DEST funding May-04 AARNet completes RFT for equipment Supplier selected and equipment costs known May-04 AARNet secures member sign-offs Agreement from participating universities and CSIRO Jun-04 AARNet provides physical connections to CSIRO sites Connections into active equipment in site computer rooms Aug-04 Production network operational with gigabit links Cutover from existing leased lines to gigabit backbone Aug-04 Research network links (first phase) operational Dedicated links operate at 1 Gb Nov-04 Benefits • • • • • eVLBI – World leader Data Grid – AVO Pulsar Timing (ATNF – Swinburne) Efficient Service delivery (one-IT) Research Net – enhance CSIRO reputation • (AREN is $42.5M project) 31/5/2004 A. Tzioumis 15 eVLBI - Opportunity • Production network will happen – Independent of eVLBI • Great opportunity – High BW connections to telescopes – Minimal cost to ATNF/Unis – “leverage” on developments • Unique opportunity – MUST take!! 31/5/2004 A.
