TAT: traffic analysis tool for the statistical study of IP networks

We present a new software package, TAT, that allows the statistical study of the IP traffic transmitted through an Internet node. This tool has been successfully tested under work carried out in a subnet of the regional network of Murcia (Spain) called Ciez@net. Cieza is a town of 30,000 people where the pilot network Ciez@net intends to give these people the opportunity to use the new emerging Internet applications in their daily life. The goal of the traffic analysis tool developed in this project has been to analyse the IP traffic transmitted in the regional network in order to figure out if the use that people make of the network services and infrastructure was worth the economic effort put into the network deployment and operation. The success of this software tool lies in its flexibility, easy handling and interface independence.
