“…MPTCP is a fully backward-compatible extension of TCP, published as an experimental standard in 2011 [25], [26], [176] and now widely deployed [177]. It allows applications to use multiple connections at the same time without any changes to the socket API.…”

Over the years, the Internet has been enriched with new available communication technologies, for both fixed and mobile networks and devices, exhibiting an impressive growth in terms of performance, with steadily increasing available data rates. The Internet research community has kept trying to evolve the transport layer protocols to match the capabilities of modern networks, in order to fully reap the benefits of the new communication technologies. This paper surveys the main novelties related to transport protocols that have been recently proposed, identifying three main research trends: (i) the evolution of congestion control algorithms, to target optimal performance in challenging scenarios, possibly with the application of machine learning techniques; (ii) the proposal of brand new transport protocols, alternative to the Transmission Control Protocol (TCP) and implemented in the user-space; and (iii) the introduction of multipath capabilities at the transport layer.

“…The code for these modifications is available online 6 , as is that of our Ryu-based controller. 7 While layer-2 path capacity was estimated using port statistics, a dynamic layer-3 equivalent was not fully implementedthe controller currently needs manual configuration of path capacities. We expect the switches could use client traffic to implement methods such as packet dispersion [33].…”

“…Layer-2 multipath topologies [e.g., 6], have been successfully deployed and used within fully-controlled data-centre networks. End-to-end multipath support throughout the public Internet is however limited [7] due to the requirement to modify end-hosts. Heterogeneous network paths also worsen the issue of packet reordering, creating head-of-line blocking delays, and sometimes leading to worse performance than single-path transfers [8].…”

Multipath forwarding consists of using multiple paths simultaneously to transport data over the network. While most such techniques require endpoint modifications, we investigate how multipath forwarding can be done inside the network, transparently to endpoint hosts. With such a network-centric approach, packet reordering becomes a critical issue as it may cause critical performance degradation.We present a Software Defined Network architecture which automatically sets up multipath forwarding, including solutions for reordering and performance improvement, both at the sending side through multipath scheduling algorithms, and the receiver side, by resequencing out-of-order packets in a dedicated in-network buffer.We implemented a prototype with commonly available technology and evaluated it in both emulated and real networks. Our results show consistent throughput improvements, thanks to the use of aggregated path capacity. We give comparisons to Multipath TCP, where we show our approach can achieve a similar performance while offering the advantage of endpoint transparency.

“…For example, in our testbed experiments presented in Section 6, 34% of source-destination pairs (the source playing the role of the gateway, the destination the role of the client) between which multiple paths exist would not support MPTCP, because the interface used by the client is common to the different paths. Finally, very few servers currently support MPTCP (less than 0.1% of the hosts in the Alexa top-1M list [26]). Contrary to MPTCP, EMPoWER acts at layer 2.5; it is therefore confined to the local network and transparent to other Internet hosts and protocols.…”

Several technologies, such as WiFi, Ethernet and power-line communications (PLC), can be used to build residential and enterprise networks. These technologies often co-exist; most networks use WiFi, and buildings are readily equipped with electrical wires that can offer a capacity up to 1 Gbps with PLC. Yet, current networks do not exploit this rich diversity and often operate far below the available capacity.We design, implement, and evaluate EMPoWER, a system that exploits simultaneously several potentially-interfering mediums. It operates at layer 2.5, between the MAC and IP layers, and combines routing (to find multiple concurrent routes) and congestion control (to efficiently balance traffic across the routes). To optimize resource utilization and robustness, both components exploit the heterogeneous nature of the network. They are fair and efficient, and they operate only within the local area network, without affecting remote Internet hosts. We demonstrate the performance gains of EMPoWER, by simulations and experiments on a 22-node testbed. We show that PLC/WiFi, benefiting from the diversity offered by wireless and electrical mediums, provides significant throughput gains (up to 10x) and improves coverage, compared to multi-channel WiFi.
