  1. AARNet IPv6 Update IPv6 Workshop APAN 24, Xi’An 2007 Bruce Morgan

  2. The AARNet Network • AARNet owns and operates a resilient and redundant multi-Gbps network across Australia. In the Eastern Australia we have deployed DWDM equipment which currently has up to 320 Gbps capacity. • Dual STM-64c (10 Gbps) links connect major capital cities with routing being done by Juniper M320 routers

  3. University connections • Universities are encouraged to have diverse connections to the Juniper M320 routers at each PoP. • Institutions typically connect at 1 Gbps and we have deployed Cisco 7304 routers at each site (edge routers), and also edge servers. This allows close monitoring of each tail circuit. • So far about 85 edge routers have been deployed.

  4. AARNet3 National Network

  5. Regional Optical Network

  6. AARNet International Network

  7. The international footprint • AARNet has a very large international footprint from the PoP in Frankfurt, Germany to Palo Alto in the US - it covers a timezone difference of 17 hours from +1 to -8 • Peering at : • Hawai’I, Seattle (Pacific Wave), PAIX, Telehouse (LA), Any2 (LA) • Singapore, Frankfurt (DE-CIX), Amsterdam (AMS-IX), London (LINX) • Currently 622 Mbps to Singapore and then on to Frankfurt • The 622 Mbps link to Singapore connects to the TEIN2 nework

  8. 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 • Catalyse Global Astronomy Initiative • Mauna Kea, Big Island

  9. TEIN2 Connectivity • There are four STM-1 circuits linking Perth to Singapore. • Two of these go via APCN, and the other two via SMW3 to provide diversity and fault tolerance • AARNet Singapore PoP establish at the Kim Chuan data centre from where we peer with TEIN2, Singaren and ASNet

  10. Commodity and R&E • AARNet offers both commodity (commercial) internet and research networking • Two 10 Gbps circuits for R&E connectivity to the US. The northern link is IP and routed - the southern link will be presented as light paths (ethernet L2 circuits) • 6 x STM-4 (3.6 Gbps) circuits to the US - terminating at Palo Alto and Los Angeles • 2 x STM-1 (310 Mbps) circuits to Seattle via Hawai’i and Fiji • 4 x STM-1 (622 Mbps) circuits to Singapore and Frankfurt – also two 100 Mbps circuits to LINX and AMS-IX

  11. AARNet support for IPv6 • AARNet3 core and edge is dual stack since 2003 • Dual stack deployed across M320 core using OSPF3 and BGP as routing protocols • IPv6 is used within AARNet • www.aarnet.edu.au IPv6 enabled • Infrastructure is IPv6 enabled • IPv6 Multicast is enabled • SSM supported • Currently use a static RP for ASM

  12. Addressing • Addressing Plan • Currently use /32 2001:388::/32 allocated by APNIC • Allocate a /40 to a PoP or a /48 to a customer • A /39 is allocated to the Tunnel broker networks • Some customers have their own allocations

  13. AARNet Migration Broker • http://broker.aarnet.net.au • Hexago appliance • Same as Freenet6 • Tunnel Setup Protocol • NAT Traversal support • Open to anyone who can reach it via a domestic Australian path

  14. Peering and Transit • International transit and peering available for IPv6 • Encouraging both IPv4 and IPv6 peering • But still many IPv4 only peers • Haven’t yet fully deployed RPSLng so IPv6 prefix filtering not as strong in the IPv4 world

  15. The customer edge • All customers can connect natively • But the customer edge is configured only on request • CPE router dual stack but customer’s router/firewall may not be

  16. Still work to be done… • DNS about to be implemented • Mail issues – 3rd parties? • Still need to deploy IPv6 measurement • IPv6 monitoring is still in its infancy within our infrastructure • IPv4 Netflow is heavily deployed – IPv6 isn’t at the moment

  17. AARNet3 is ready… • A few institutions are using IPv6 natively in a limited fashion • Many are worried about deploying a dual stack at the edge • Stability/complexity concerns • Existing infrastructure may not support IPv6 • Firewalls • Web services • Some institutions and researchers use static tunnels or broker

  18. Some progress… • Fiji is now advertising IPv6 routes • More customers are deploying IPv6 • But still a snail’s pace • Uptake of IPv6 has been slow • Lack of IPv6 specific spplications • Not a huge amount of IPv6 services available • No shortage of IPv4 address space within institutions • Legacy and non-IPv6 compliant equipment • Security • Management

  19. IPv4 address depletion • 2009? • 2012? • 2015? • When will it kick in? • Will it effect our customers/institutions immediately? • Will it be a painful process?

  20. Where to from here? Ensure as many services as possible are IPv6 enabled • Encourage customer connections • Look for more peering opportunities • Encourage IPv6 activities • Education on setting up IPv6 to institutions
