There are various tools, utilities, and applications that we use during the Imagine Cup IT Challenge.
The image above displays a network traffic matrix for all network communication in the IT Challenge. Each line in "The Eye of Sauron" represents network traffic between two hosts. This is captured on the judge's Microsoft ISA 2006 server since it's the focal point for the network.
Other tools we use are network packet sniffers, protocol analyzers, and network packet regeneration tools. We use these tools so we can verify that the competitors' builds are working properly, as well as monitor and troubleshoot network issues.
