“…By getting closer to our approach, an interesting related work is presented by Rahman et al 34 and Raina et al, 35 in which the single congestion control Compound TCP (CTCP) has been tested as a function of the AQM algorithm used on the gateway node. Unfortunately, this analysis is limited to the old Random Exponential Marking (REM) and the simple Drop-Tail AQMs, considering the buffer size again as a parameter.…”

Most Internet traffic is carried by the Transmission Control Protocol (TCP) nowadays, even in the case of real-time services. Detecting and mitigating the congestion is one of the primary tasks of this protocol, in fact, different TCP versions are defined by their congestion control algorithms. Furthermore, Active Queue Management (AQM) algorithms share the same goal of congestion mitigation with TCP; in particular, the most efficient congestion control occurs when AQM and TCP work together. This paper presents a brief survey and a cross-comparison of the latest and most important TCP and AQM variants, then provides an evaluation of a different kind of performance on the ns-3 network simulator over various types of environments (multiple Round Trip Time, long delay, different congestion levels, etc.). In any shared bottleneck, the choice of the TCP-AQM couple to adopt is crucial. We will show that the results are not univocal and the “one size fits all” solution does not exist. Moreover, the proper couple depends on the performance that we want to boost and on the environment that we have to deal with.

“…Nevertheless, some attempts exist. As an example, an interesting related work is represented by [23], [24] in which a single proposed TCP congestion control, named Compound TCP (C-TCP), has been tested as a function of the AQM algorithm used on the gateway node. Unfortunately, this analysis is limited to the old REM and the simple DropTail AQMs, also considering, in this case, the buffer size as a parameter.…”

“…To highlight the effect of congestion control obtained by selecting the proper AQM in multiple environments, we developed a testbed within the ns3 network simulator. The network topology used is the classical dumb-bell topology reported in Figure 1 and compliant to the topology used in many of the related works on congestion control study like [3], [24]- [26], [29]- [34]. The parameters used in our simulations are summarized in Table I; they represent two distinct access networks, connected with a bottleneck link that is accessible to the end hosts of each network through a border gateway.…”

Most of the Internet traffic is carried by Transmission Control Protocol (TCP) nowadays, even in the case of real-time services and IoT environments. A key point of each TCP variant that defines the specific variant trademark is the congestion control algorithm. This congestion control, alone, is not able to mitigate the congestion problem completely; the most efficient solution, to be coupled with it, is the Active Queue Manager (AQM). In this paper, we analyze the response to congestion provided by the novel AQMs when coupled with popular TCP variants and, has happened in IoT networks, with a mix of TCP variants simultaneously active on the network. We provide extensive simulations within ns-3 to highlight what is the better AQM solution for IoT networks by considering the TCP algorithm and other environmental conditions like the number of active nodes, the network RTT and the presence of multiple RTT flows. We collected network metrics like throughput, goodput, latency, RTT variation, flows' fairness and a simple drop analysis.

“…A large number of papers have studied the performance of TCP and ECN; see [8,[19][20][21] as a not exhaustive list, but the main focus is on the behavior of a single TCP connection under various scenarios. Other works focused on the specific TCP versions installed by default in the Linux and Windows operating systems and developed models studying their performance [22][23][24]. More similar to the analysis carried out here are those proposed in [9,25,26] where the authors consider the overall system performance in the mean field limit for ECN/RED.…”

We consider the scenario in which several TCP connections share the same access point (AP) and a congestion avoidance/control mechanism is adopted with the aim of assigning the available bandwidth to the clients with a certain fairness. When UDP traffic with real-time requirements is present, the problem becomes even more challenging. Very well-known congestion avoidance mechanisms are the Random Early Detection (RED) and the Explicit Congestion Notification (ECN). More recently, the Smart Access Point with Limited Advertised Window (SAP-LAW) has been proposed. Its main idea is that of computing the maximum TCP rate for each connection at the bottleneck, taking into account the UDP traffic to keep a low queue size combined with a reasonable bandwidth utilization. In this paper, we propose a new congestion control mechanism, namely, Smart-RED, inspired by SAP-LAW heuristic formula. We study its performance by using mean field models and compare the behaviours of ECN/RED, SAP-LAW, and Smart-RED under different scenarios. We show that while Smart-RED maintains some of the desirable properties of the SAP-LAW, it solves the problems it may have in case of bursty UDP traffic or TCP connections with very different needs of bandwidth.
