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.

This page is part of the GENIUS project.

Tcpdump and Pkthisto 0.1.3 software running on Packet Sniffing Computer

Microsoft Xboxes use the following addressing for packets:

Pkthisto 0.1.2 only analyses UDP/IP flows. A small modification was made to allow pkthisto to differentiate Ethernet-level flows using the Ethernet MAC addresses rather than UDP port and IP address information.

Calibration of Sniffer Boxes' Ethernet Port

Calibration was performed for both Sniffer Boxes' Ethernet port used for traffic capturing using a NetCom Systems SMARTBITS2000 with a SX-7 410B line card.

The SmartBits 2000 was configured to send long (500 and 1000 packet) bursts of back-to-back packets to each sniffer computer, with intervals ranging from 12.5usec to 50msec. We found that both computers were capable of timestamping to less than ten microseconds accuracy, even when subjected to bursts of 1000 packets spaced tens of microseconds apart. This was considered sufficient accuracy for our first Xbox analysis (where we are discussing intervals to the nearest millisecond).
