“…Transmission protocols continue to evolve to meet the emerging needs of users and new services. Corbel et al [14] specifically analyzed the protocol fairness when TCP and QUIC streams coexist on the wireless link of the mobile network. The results show that when the loss rate of the mobile network is low, the emulation of multiple TCP connections, the limitation of the congestion window size, and the use of hybrid start (hystart) have a great impact on fairness.…”

Congestion control is a fundamental technology to balance the traffic load and the network. The Internet Engineering Task Force (IETF) Quick UDP Internet Connection (QUIC) protocol has flexible congestion control and at the same time possesses the advantages of high efficiency, low latency, and easy deployment at the application layer. Bottleneck bandwidth and round-trip propagation time (BBR) is an optional congestion control algorithm adopted by QUIC. BBR can significantly increase throughput and reduce latency, in particular over long-haul paths. However, BBR results in high packet loss in low bandwidth and low fairness in multi-stream scenarios. In this article, we propose the enhanced BBR congestion control (eBCC) algorithm, which improves the BBR algorithm in two aspects: (1) 10.87% higher throughput and 74.58% lower packet loss rate in the low-bandwidth scenario and (2) 8.39% higher fairness in the multi-stream scenario. This improvement makes eBCC very suitable for IoT communications to provide better QoS services.

“…To assess the limit of the available bandwidth, Hystart mainly checks the RTT increases. With variable or high latency, Hystart may exit prematurely the slow start phase [20], [21]. We evaluate its impact in Section III-C1.…”

This paper assesses the benefits of using Sliding Windows Forward error codes (SWF) to protect transport protocol sessions over a SATCOM link within IP tunnels. We consider two commonly deployed protocols and congestion control algorithms : TCP/CUBIC, currently deployed by default inside most of recent OS kernels and a QUIC/BBR implementation named Picoquic. Our objective is to evaluate the performance of these protocols in challenging SATCOM environments and to assess if SWF can contribute to improve their performance. We consider two different scenarios based on real loss mobility patterns played over the OpenSAND satellite emulator. Results show that using SWF tunnels can hide losses to a CUBIC server: this reduces the download time of 20MB by more than 90%. However, the main finding is that SWF does not contribute to the download time reduction for BBR, making useless its deployment. We conclude that the use of BBR over SATCOM could be an efficient way to perform communications over unreliable links, resulting from a high mobility context for instance, considering BBR flows are managed by an adequate QoS allocation.
