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.

MAPPING -- Measuring And Practically Predicting INternet Growth

Measuring and predicting growth in Internet addressing, routing complexity and energy usage

Tools released or used by the project
Name Description
FPS game server probe traffic animation scripts A collection of scripts used to generate animations showing the distribution of FPS game clients across the globe.
STING ping (sping) A tool for pinging huge numbers of IP addresses with ICMP echo and TCP SYNs, and/or performing huge numbers of reverse DNS lookups. By default sping pings each address multiple times to get some topology information, but it can also be used for simple pinging like the well known ping tool.
For more information see the sping home page. Old versions:
Secure Fast Set Intersection (SeFaSI) A tool for secure and fast computation of the intersection cardinality of multiple datasets. SeFaSI was developed primarily so that capture-recapture techniques can be used to estimate the size of the IPv4 space based on datasets of IP addresses observed collected by multiple collaborators, while ensuring the anonymity of the IP addresses each collaborator has observed.
For more information see the SeFaSI home page. Old versions:
IP Capture Recapture (IPCR) Tool A tool for estimating the used IP space with Capture Recapture (CR) analysis based on log-linear models. The tool is written in the R language and can be excuted with the R interpreter. IPCR Tool takes capture history files produced by SeFaSI as input and produces CR population estimates as output.
IPv4 address datasets Several datasets of unique IPv4 addresses collected for 3-month time intervals from several sources during the years 2011 to 2014.
NAT Test Test whether you are behind a NAT. The test will tell you the external and internal IP addresses of your client.
