1. AARNet Network Update
IPv6 Workshop
APAN 23, Manilla 2007
AARNet

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. The AARNet Network(2)
At each capital city there are two geographically separated Points of Presence (PoPs) interconnected with 10 Gbps ethernet circuits. Cisco 6509-NEB-A switches are used to terminate the intra-PoP links
Remoter cities - Darwin, Alice Springs and Hobart - are currently connected by dual STM-1 (155 Mbps) circuits - terminated on Juniper M20 routers

4. 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 75 edge routers have been deployed.

5. Domestic Network

6. Equipment Backbone routers are Juniper M320s
Smaller PoPs have Juniper M20 routers
Backbone switches for interconnecting PoPs are Cisco 6509-NEB-A
Cisco 7304 NPE at institutions - some 85 deployed
Cisco ONS MSPP for DWDM on the optical network

7. Regional Network

8. The Optical Network

9. The AARNet DWDM Backbone
Provisioned for 16 wavelengths today
Expandable to 32 wavelengths
40G (STM256) compatible

10. International Network

11. 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)
Singapore, Frankfurt (DE-CIX), Amsterdam (AMS-IX)
, Currently 622 Mbps to Singapore and then on to Frankfurt
The 622 Mbps link to Singapore connects to the TEIN2 nework

12. 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

13. 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

14. 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)
4 x STM-4 (622 Mbps) circuits to the US - two terminating at Palo Alto, the other terminating in Los Angeles
These will be upgraded to 2 x STM16 circuits (2.5Gbps)
2 x STM STM-1 (155 Mbps) circuits to Seattle via Hawai’i and Fiji

15. AARNet support for IPv6 AARNet3 core and edge is dual stack
Still need to make services accessible via IPv6
Web server isn’t
International transit and peering available for IPv6
All customers can connect natively
CPE router dual stack but customer’s router/firewall may not be
IPv6 Multicast is enabled
SSM supported
Currently use a static RP for ASM

16. AARNet Migration Broker
Hexago appliance
Same as Freenet6
Tunnel Setup Protocol
NAT Traversal support
Open to anyone who can reach it via a domestic Australian path

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
Some institutions and researchers use static tunnels or broker
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

18. Where to now? Ensure as many services as possible are IPv6 enabled
Connect customers if they ask
Look for more peering opportunities
Encourage IPv6 activities
AARNet sponsored and provided native connectivity to IPv6 Summit in Canberra, 4-6 December 2006

19. Thank You!
