Abstract

In this paper we have compared the performance of three traffic generators (DITG, packETH, Ostinato) over a 40Gbps link. In our laboratory experiment, two computers with Linux operating systems are connected through a 40Gbps link. The payload size was varied from 64 to 8950 bytes and TCP and UDP traffic on the link was measured. To achieve the maximum throughput jumbo frames were used. The results showed significant changes in performance of tools for TCP and UDP traffic respectively. For both TCP and UDP traffic only PackETH was able to achieve the highest throughput of 39.8Gbps. D-ITG running in a single threaded mode was not able to utilize the full bandwidth so its performance is evaluated in multi-threaded mode with 16 threads.
