    Design and implementation of AQM evaluation suite for ns-3
    (Association for Computing Machinery acmhelp@acm.org, 2017) Deepak, A.; Shravya, K.S.; Tahiliani, M.P.
    Excessive buffering in network devices should be avoided because it leads to a series of performance issues such as high queuing latency and variations in delay. Active Queue Management (AQM) algorithms play a vital role in monitoring and controlling the queue length in these devices. Recently there has been a significant progress in the design and development of new AQM algorithms. However, thoroughly evaluating the performance of AQM algorithms is a nontrivial task. In an effort to simplify this, the Active Queue Management and Packet Scheduling Working Group at IETF have proposed informational guidelines in RFC 7928 to test the applicability, performance and deployment complexity of AQM algorithms. This paper presents the design and implementation of an AQM evaluation framework for ns-3 which helps to quickly study the performance of AQM algorithms based on the guidelines mentioned in RFC 7928. The proposed framework automates simulation setup, topology creation, trafiéc generation, program execution, results collection and their graphical representation using ns-3, based on the scenarios mentioned in the RFC. © 2017 ACM.

    Common TCP evaluation suite for ns-3: Design, implementation and open issues
    (Association for Computing Machinery acmhelp@acm.org, 2017) Nagori, K.; Balachandran, M.; Deepak, A.; Tahiliani, M.P.; Chandavarkar, B.R.
    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 traéc, and is designed in line with the recommendations from Internet Congestion Control Research Group (ICCRG). We discuss the Tmix integration in ns-3, shu.ing 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. © 2017 ACM.
