  1. TEIN2 Kick-Off WSAARNet

  2. AARNet3 Network Highlights • STM-64c (10Gbps) Backbone • Dual STM-1 to NT & Tasmania • Replacing Procket with Juniper M320 • Deploying DWDM from Adelaide to Brisbane • Providing multiple GigE to regional areas • Rolling our backbone onto our DWDM kit • Multiple trans Pacific circuits • 2 x STM-64c for (10Gbps) research and education • 4 x STM-4c (4 x 622Mbps) for commodity • 2 x STM-1 • Looking to expand footprint to Asia © 2005, AARNet Pty Ltd

  4. Network Operations • A small NOC Team mainly based in Perth (4 people) • Support with state based managers and technical staff • 24x7 Contact point managed by outsourced call centre • 24x7 Monitoring by Nagios – email and SMS warnings • SNMP Management of the Network • 100% Netflow enabled at the customer edge • Currently 63 routers expanding to 80 at end of year • Over 8,000 kms of fibre • Moving to DWDM © 2005, AARNet Pty Ltd

  5. Security • High importance in the modern high bandwidth network • Proactively monitor • Netflow enabled to easily detect attacks • Actively participate with other NOCs to detect intrusions, bots and mitigate attacks. © 2005, AARNet Pty Ltd

  6. 10G Trans Pacific • Partnership with Southern Cross Cable Networks • AUP - Research and Education only • Dual STM-64c (OC192) • Northern path to Seattle • Layer 3 routed • Southern path to Los Angeles • Layer 1/2 - more later • Catalyse Global Astronomy Initiative • Mauna Kea, Big Island © 2005, AARNet Pty Ltd

  7. Why is a R&E network different? • Peak demand can be driven by a single user driving a single application • Interest in advanced services • IPv6 • Voice, video, multicast • Latency important to some but others more interested in bandwidth • Need to build for peak demand • So that means lots of “white space” • But “Nature abhors a vacuum” … © 2005, AARNet Pty Ltd

  8. IPv6 • Just plumbing but … • Unlike GOSIP it needs to be taken seriously • Important to Asia • End-to-end principle • First Australian IPv6 Summit • http://www.isoc-au.org.au/ipv6summit/ • October 2005 © 2005, AARNet Pty Ltd

  9. How does AARNet support IPv6? • AARNet3 is dual stack • International transit/peers • All customers can connect natively • AARNet Migration Broker • http://broker.aarnet.net.au • Hexago appliance • Same as Freenet6 • Open to anyone who can reach it via a domestic path © 2005, AARNet Pty Ltd

  10. Divide Network Users into 3 Categories • Cees de Laat classifies network users into 3 broad groups. • Lightweight users, browsing, mailing, home use. Who need full Internet routing, one to many; • Business applications, multicast, streaming, VPN’s, mostly LAN. Who need VPN services and full Internet routing, several to several + uplink; and • Scientific applications, distributed data processing, all sorts of grids. Who need very fat pipes, limited multiple Virtual Organizations, few to few, peer to peer. © 2005, AARNet Pty Ltd

  11. Who are these Type “3” Users? • How many times can you say “CERN”? • Astronomers, eVLBI • Synchrotron • Music Master Class • High Definition TV over IP • Massive data transfers from experiments running 24x7 © 2005, AARNet Pty Ltd

  12. High Definition TV over IP demo • Joint AARNet & Research Channel demo for SC2004 • Uncompressed signal • ~2million pixels per frame • 60 frames per second interleaved • using 1.5Gbps for each stream • Used 10Gbps circuit from Canberra to Pittsburgh • During the 30 hours of demonstration, 20 Terabytes of data were transmitted in each direction. • No custom equipment involved, all off-the-shelf components © 2005, AARNet Pty Ltd

  13. EXPReS and Square Kilometre Array • SKA bigger data generator than LHC • But in a remote location Australia one of countries bidding for SKA – significant infrastructure challenges AARNet and CSIRO ATNF are partners in EU Commission funded EXPReS project to link 16 radio telescopes around the world at gigabit speeds © 2005, AARNet Pty Ltd

  14. Huygens Space Probe • Cassini spacecraft left Earth in October 1997 to travel to Saturn • On Christmas Day 2004, the Huygens probe separated from Cassini • Started it’s descent through the dense atmosphere of Titan on 14 January 2005 © 2005, AARNet Pty Ltd

  15. Tracking the Descent • Very Long Baseline Interferometry (VLBI) is a technique where widely separated radio-telescopes observe the same region of the sky simultaneously to generate images of cosmic radio sources • Using this technique 17 telescopes in Australia, China, Japan and the US were able to accurately position the probe to within a kilometre (Titan is ~1.5 billion kilometres from Earth) © 2005, AARNet Pty Ltd

  16. Australian Contribution • Created “dedicated” circuit • The data from two of the Australian telescopes (Parkes [The Dish] & Mopra) was transferred via light plane to CSIRO Marsfield (Sydney) • CeNTIE based fibre from CSIRO Marsfield to AARNet3 GigaPOP • SXTransPORT 10G to Seattle • “Lightpath” to Joint Institute for VLBI in Europe (JIVE) across CA*net4 and SURFnet optical infrastructure © 2005, AARNet Pty Ltd

  17. Australian Contribution • The data was transferred at an average rate of 400Mbps • 1Gbps path was available, TCP stack tuning important • The data from these two telescopes were reformatted and correlated within hours of the end of the landing • This early correlation allowed calibration of the data processor at JIVE, ready for the data from other telescopes to be added VLBI Fringes © 2005, AARNet Pty Ltd

  18. AARNet middleware In-house developments • Develop a middleware architecture framework for development activities. • Roll out eduroam to AARNet offices and staff. • Gain practical experience of Shibboleth by • Creating an AARNet Identity Provider system for AARNet staff and join MAMS federation. • Assessing the feasibility of shibbolising AARNet applications and services. • Further development AARNet’s middleware website to generate awareness; © 2005, AARNet Pty Ltd 18

  19. AARNet middleware Joint activities • Involvement in national middleware initiatives involving education and research communities. • CAUDIT Identity and Access Management survey 2005. • Participation and assistance in eduroam Australia roll out, development and policy. • Participation in • global eduroam development and policy. • CAUDIT PKI Technical Working Group in developing a national PKI. • Global middleware policy. © 2005, AARNet Pty Ltd 19
