Common TCP Evaluation Suite for ns-3: Design, Implementation and Open Issues

This paper presents the design and implementation of a Common TCP Evaluation Suite for ns-3. The proposed evaluation suite uses Tmix to generate realistic synthetic TCP traffic, and is designed in line with the recommendations from Internet Congestion Control Research Group (ICCRG). We discuss the Tmix integration in ns-3, shuffling connection vectors of the real traces, architecture and validation of the proposed evaluation suite. The correctness of the evaluation suite is verified by comparing the results obtained from it to those from an existing implementation of such a suite in ns-2. Several open issues discovered with Tmix are also discussed in the paper.
