A Distributed Multiplatform Architecture For Traffic Generation

This paper deals with the specification and realization of a synthetic traffic generator for IP traffic, called D-ITG (Distributed Internet Traffic Generator). We point our attention on the innovative architectural choices and the consequent interesting results. Indeed, thanks to the novel proposed distributed architecture, D-ITG reaches the highest performance over all the considered platforms and it shows interesting and innovative features in terms of supported protocols, available traffic patterns and meters type. In a heterogeneous network scenario, we think that D-ITG is an essential tool for network testing and planning activities. We compared our tool with several of the currently available and most widely adopted traffic generators and we found that D-ITG offers several improvements in terms of both functionalities and performance. The presented architecture and the comparative analysis shown in this work confirm our assumption.
