Data preprocessing for efficient evaluation of network traffic parameters

This paper deals with recent results of a supporting mechanism for efficient evaluation of network traffic parameters. Most of the network monitoring tools store the measured data in a database for the later analysis. With the growth of the data in the database, processing of queries is becoming more and more time consuming. This fact results in an excessive response time of the database, which subsequently brings an adverse impact on the monitoring tool. While most of the monitoring tools make evaluations on the basis of outdated data from a database, the vast majority of them have to deal with this problem. In this contribution a new approach of efficient network traffic data evaluation through a database will be introduced, while the main attention will be dedicated to the implementation details.
