Dr. Jason But - Research Portfolio
Projects
Since joining CAIA I have been involved
in a number of different Research Projects. This page contains a brief description
of and links to these individual projects.
SONATA - FreeBSD implementation of an SCTP friendly NAT
Funded by a Cisco
Competitive URP Grant. The program is developing a NAT implementation that can
support the SCTP protocol. This implementation
will then be analysed for performance implications and security issues facing
a NAT implementation for this protocol.
Analysis of BitTorrent Performance in a Content Caching Context
Funded by Swinburne
University. This project explores the performance of the popular peer-2-peer
BitTorrent protocol and seeks to answer the question of how fair it is. Unlike other
work with BitTorrent which relies on simulation, we have deployed and measured
BitTorrent traffic between a dedicated BitTorrent network including up to 60
virtual computers.
SITCRC - Smart Internet Technologies - Smart Networks, Stream 4
Funded by the Smart Internet CRC, this
project had its origins in an earlier CAIA based
project GENIUS. The project consisted of
two sub-projects:
- SONG
- providing a suite of traffic simulation and modelling tools so ISPs can predict
the impact of highly interactive applications (such as games) on their networks
- ANGEL
- developing an automated approach to network re-configuration in response
to detection of game traffic in the network
More information on this project can be found here...
BART - Broadband Access Research Testbed
BART is an in-house testbed for research
into the performance characteristics of IP applications running over "broadband"
access networks such as DOCSIS cable, ADSL, and 802.11. The network is configured to
support three virtual ISPs which provide Internet Access to modem connected devices
via the Swinburne network. BART allows us to deploy servers at any point in the ISP
network environment and test applications using real, consumer-grade broadband access
links. My responsibilities include configuring and managing access to BART for any
CAIA research projects
ICE3 - Inverted Capacity Extended Engineering Experiment
ICE asks the question:
What would happen if most of the Internet's capacity was at the edges, and
content was pushed to caches in every suburb and city?
Work on this project has led to the development of NetSniff,
a tool to capture and analyse application layer network traffic from within the network core.
Past Projects
In my prior position at Monash University I have also
participated in a number of projects as listed below:
- ATcrc
- Development of Real-Time traffic generators and IPv6 Video Streaming Server software
- McIVER
- Joint project with SGI and Cinemedia to deploy streaming video of Australian
movie content to high schools across Australia
