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

In this paper, we present a new software package, TAT, that allows the statistical study of the IP traffic transmitted trough an Inter-net node. This tool has been successfully tested under a work carried out in a subnet of the regional network of Murcia (Spain) called Ciez@net. Cieza is a village of 30,000 people where the pilot network Ciez@net intends to bring 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 economic effort done during the network deployment and operation was worth enough regarding the use that people do of the net-work services and infrastructure. The success of this software tool lies on its flexibility, easy handling and interface independence.
