Testing networking devices before releasing them to the market is a way of ensuring their quality and robustness. Replay technique with artificial or real-world traffic is a method used to test networking devices. Using real-world traffic is more preferable as it displays more realistic properties in comparison with artificial traffic. The challenges with testing products with real-world traffic are mainly the high volume of the captured traces and the prolonged time required for the replay testing. In order to efficiently reproduce the defects produced by networking devices and reduce the replay time, it is necessary to reduce the size of the traces that trigger the defect of networking devices. In order to perform a defect-based traces downsizing, we propose a binary and a linear downsizing algorithms respectively based on binary and linear search algorithms. A metric called downsizing ratio is defined is order to evaluate the efficiency of the traces downsizing. The evaluation of the defects distribution show that ICMP and HTTP defects represent around 60% of the total number of defects experienced by networking devices. In addition, the binary downsizing and linear downsizing achieve a downsizing ratio of 77% and 80% respectively. As a result, the time needed to perform testing is reduced by the same amount. This is significant since the downsizing techniques used can improve the testing of networking devices.
