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

IPv6
Just plumbing but
Unlike GOSIP it needs to be taken
seriously
Important to Asia End-to-end principle

Divide Network Users into 3 Categories
Cees de Laat classifies network usersinto 3 broad groups.
1. Lightweight users, browsing, mailing, home
use. Who need full Internet routing, one to
many;
2. Business applications, multicast, streaming,
VPNs, mostly LAN. Who need VPN services
and full Internet routing, several to several +
uplink; and
3. Scientific applications, distributed data
processing, all sorts of grids. Who need veryfat pipes, limited multiple Virtual
Organizations, few to few, peer to peer.

Who are these Type 3 Users?
How many times can you say CERN?
Astronomers, eVLBI
Synchrotron
Music Master Class High Definition TV over IP

High Definition TV over IP demo
Joint AARNet & Research Channel demo forSC2004 Uncompressed signal
~2million pixels per frame
60 frames per second interleaved
using 1.5Gbps for each stream
Used 10Gbps circuit from Canberra toPittsburgh
During the 30 hours of demonstration, 20Terabytes of data were transmitted in each
direction.
No custom equipment involved, all off-the-shelfcomponents

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 its descent through the dense
atmosphere of Titan on 14 January 2005

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 radiosources
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)

Australian Contribution
Created dedicated circuit
The data from two of the Australiantelescopes (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 inEurope (JIVE) across CA*net4 andSURFnet optical infrastructure

Australian Contribution
The data was transferred at an averagerate of 400Mbps
1Gbps path was available, TCP stacktuning important
The data from these two telescopeswere reformatted and correlated withinhours of the end of the landing
This early correlation allowed calibration
of the data processor at JIVE, ready forthe data from other telescopes to beadded
