Análisis y caracterización del tráfico IP en la red regional Ciez@net

Abstract

In this paper, we present the most significant results studying the Internet network traffic measurements obtained in Ciez@net. Ciez@net is a citizen subnet located in the village of Cieza that belongs to the regional network of the Autonomous Community of Murcia in Spain. This subnet is one of the firsts pilot experiences of a Digital City in Europe and the first in the Region of Murcia. The goal is the seamless introduction of the Information Society in a medium-size population. Access to advanced electronic information services is stimulated or subsidized for an effective penetration. These measurements will allow a qualitative and quantitative knowledge of the network traffic in order to achieve a most effective network resource provisioning and Internet traffic forecasting in a real scenario. A suitable dimensioning of the network as well as an adequate provisioning of Quality of Service to users may depend partially on these results. Measurements were taken from a Frame Relay link connecting Ciez@net users to Internet through the main node located in Murcia city. We used a promiscuous network analyzer that avoids interfering with network traffic. We report results of traffic load, network performance, percentage composition of traffic by protocol and type of application, and IP packet size distribution in both up and down communications streams.
