SXTransPORT
Southern Cross Trans Pacific Optical Research Testbed
• AARNet and Southern Cross Cable Network (SX) worked
together to connect Australia’s research community at
unprecedented speed to the global cyberinfrastructure
• The Southern Cross Trans-Pacific Optical Research Testbed
(SXTransPORT) partnership was announced on 11th
December 2003 with support from the Australian Government
• Dual 10Gbps circuits between Australia and US West Coast
• AARNet interconnects SXTransPORT at Pacific Wave to
other global research networks, and in Sydney to AARNet3
(Australia’s multi-path 10Gbps trans-continental research
network based on Nextgen fibre)

SXTransPORT
Southern Cross Trans Pacific Optical Research Testbed
• Acceptable Use Policy applies on the 10Gbps circuits –
R&E institutions only, no commodity or commercial transit
(separate 622Mbps circuits are used for commodity to PAIX
and Telehouse America, LA)
• Provides affordable (subscription-based) high throughput
allowing Australia to effectively participate in global escience initiatives
• Strengthens the case for locating major international
infrastructure (like the Square Kilometre Array) in Australia

Uncompressed HDTV interactive multimedia (1.4Gbps)
• At the exhibition floor of the Pittsburgh SC 2004 conference, AARNet
and ResearchChannel demonstrated high definition real-time video
interaction between Canberra Australia, Seattle and Pittsburgh
• ~2million pixels per frame; 60 frames per second interleaved; using
1.4Gbps for each stream; video quality amazing
• During the 30 hours of demonstration, 20 Terabytes of data were
transmitted in each direction
• No custom equipment involved, all off-the-shelf components
• A compressed HDTV demonstration (cf the uncompressed version
described above) was demonstrated at the Pacific
Telecommunications Council (PTC) 2005 conference in Hawaii
• The compressed version runs at (only?) 270Mbps. The capacity
limitations at the venue (1Gbps) prevented use of uncompressed
6
Uncompressed HDTV interactive video (1.4Gbps)
• Remember this is a single application,
• seven streams of uncompressed HDTV would saturate a
10Gbps link!
• The paths used for the Pittsburgh demo were
–Canberra to Sydney on AARNet3 (10Gbps)
–Sydney to Hillsboro on SXTransPORT (10Gbps)
–Hillsboro to Portland to Seattle on NLR (10Gbps)
–Seattle to Pittsburgh on NLR (10Gbps)
• The first three paths were used for the PTC demo, but
with an additional ‘drop’ at Kahe Point, Oahu to Honolulu

Futures for research networking
- Hybrid Optical Packet Networks
• Routed networks still good for most users
• Some users have special needs
–massive data transfers
–use protocols that could impact others, or others
impact them
• Best to remove them to their own lambdas, to contain
them in a way that satisfies their needs without
detrimental impact on others (and vice-versa)
11
Global Lambda Infrastructure Facility (GLIF)
• A facility to support the real-time transfer of massive
amounts of data to facilitate emerging e-research
initiatives
• Lambda infrastructure owners “pool” circuits not in use
for their own requirements to make available to other
members on an agreed basis
• To be based on interconnect or access agreements
• Register will be maintained with conditions as basis of
scheduling
• Lightweight governance structure
12
Meshing SXTransPORT into GLIF
• Hybrid Optical Packet approach
• Retain the “northern” circuit (to Oahu and
Seattle) as 10Gbps layer 3
• Deploy the “southern circuit” (to Spencer Beach
(and Mauna Kea) as switched lightpath
(possibly 8 x 1 Gbps)
• Use several of the 1 Gbps circuits for circuit
swapping (eg with CANARIE or SURFnet) or
for the GLIF pool

Huygens Space Probe lands on Titan - monitored by 17
telescopes in Australia, Japan, China and the US
• In October 1997, the Cassini spacecraft left Earth to
travel to Saturn
• On Christmas day 2004, the Huygens probe separated
from Cassini and on 14 January 2005 started it’s
descent through the dense (methane, nitrogen)
atmosphere of Titan (speculated to be similar to that of
Earth billions of years ago)
• The signals sent back from Huygens to Cassini were
monitored by 17 telescopes in Australia, China, Japan
and the US to accurately position the probe to within a
kilometre (Titan is ~1.5 billion kilometres from Earth)

Australian eVLBI data sent over high speed
links to the Netherlands
• The data from two of the Australian telescopes were
transferred to the Netherlands over high-speed links and
were the first to be received by JIVE
• The data was transferred at an average rate of 400Mbps
(a rate that would fill a CD every 13 seconds!)
• The data from these two telescopes were reformatted and
correlated within hours of the end of the landing
• This early correlation allowed early calibration of the data
processor at JIVE, ready for the data from other
telescopes to be added
• Significant international collaborative effort
17
Global Collaboration
• The data on IDE disks was flown from Parkes (The Dish) and
Coonabarabran (Mopra) to Marsfield in Sydney
(CSIRO Australia Telescope National Facility, Au)
• This data was transferred to AARNet’s UTS International
GigaPoP using a dedicated GbE path provided by CeNTIE,
one of Australia’s Advanced Network Program (ANP)
initiatives
• Backhaul to the Southern Cross landing station in Sydney was
provided on a 10Gbps circuit on AARNet’s fibre from UTS)
• Transit to Pacific Wave (US) was engineered on a path of the
northern 10Gbps circuit of SXTransPORT, a joint initiative of
Southern Cross Cable Networks (SCCN,NZ/BM) and AARNet
18
Global Collaboration
• AARNet’s 8812 Procket at Pacific Wave was connected to a
CANARIE (CA) switch and a User Controlled LightPath
(UCLP) set up at 1GbE to the Joint Institution for VLBI in
Europe (JIVE, NL)
• The Physical path for the UCLP involved the use of CAnet4
(CA) from Pacific Wave to the ManLan (US) facility in New
York; the Internet Educational Equal Access Foundation’s
(IEEAF, US) trans-Atlantic capacity to the SURFnet, NL
GigaPoP in Amsterdam; and one of six GbE paths from the
SURFnet GigaPoP to the JIVE facility at Dwingeloo
• The possibility of this was discussed after Guido Aben’s
(SURFnet) participation in the Australian Middleware forum in
mid-December and the whole arrangement, including concept,
coordination, set-up, testing and the experiment itself was
accomplished in a little over three weeks.

Where next for e-astronomy? – in Australia
• AARNet working with members of the Australian
Astronomy community to take fibre/wavelengths all the
way to the telescopes and working with our overseas
colleagues to facilitate new joint e-astronomy initiatives

Where next for e-astronomy? –
Global Astronomy initiative – Mauna Kea, Hawaii
• Next week Bill St Arnaud, David Lassner, John Silvester,
AARNet, and astronomers from the Canada France
Hawaii Telescope (CFHT) will meet at Weimea to
progress options for high capacity connections on the big
island to the Mauna Kea summit and the base stations at
Hilo and Weimea
• A number of challenges (monopoly telco, volcanic rock,
native land rights)
• Significant interest by other telescope owners
26
In conclusion
• Recent demonstrators have shown an unprecedented
willingness to collaborate globally for the collective good
• An exciting array of new opportunities is emerging – we
need the will and determination to bring these to reality
