Internet measurements and data study over the regional network Ciez@net

Abstract

In this paper we present the most signifcant 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 trafJic in order to achieve a most effective network resource provisioning and Internet trafic 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’s users to Internet through the main node located in Murcia city. We used a promiscuous network analyzer that avoids intelfering in the network trafic. We report results of traffic load, network pelformance, percentage composition of trafJic by protocol and type of application, and IP packet size distribution in both, up and down communications streams.
