As part of a broader organisational restructure, data networking research at Swinburne University of Technology has moved from the Centre for Advanced Internet Architecture (CAIA) to the Internet For Things (I4T) Research Lab.

Although CAIA no longer exists, this website reflects CAIA's activities and outputs between March 2002 and February 2017, and is being maintained as a service to the broader data networking research community.

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
