Network Connections – e-VLBI Tasso Tzioumis ATNF

31/5/2004A. Tzioumis2 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

31/5/2004A. Tzioumis3 The NextGen Network

31/5/2004A. Tzioumis4 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

31/5/2004A. Tzioumis5 Network speeds & costs Coarse Wave Division Multiplex (CWDM) – 8 x 1 Gb/s –Relatively inexpensive –Lifecycle 3-4 years –CSIRO $1-1.5M + $ k/year Dense Wave Division Multiplex (DWDM) –80 x 10 Gb/s (or 40 Gb/s) –CSIRO $ M + $ k/year –Lifecycle >10 years

31/5/2004A. Tzioumis6 “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

31/5/2004A. Tzioumis12 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

31/5/2004A. Tzioumis13 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

Key Milestones Event/MilestoneDeliverableDate AARNet secures AREN funding Agreement with DEST 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

31/5/2004A. Tzioumis15 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)

31/5/2004A. Tzioumis16 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!!
