“…To pinpoint out our motivation, we first discuss related work that implement MPTCP using SDN and then explore the applicability of SR for traffic engineering solutions in 5G SDN-based networks. In [2] a proposal that uses MPTCP in OpenFlow-enabled networks to guarantee subflows of the same MPTCP connection to be sent through disjointed paths is given. A QAMO-SDN, QoS-aware MPTCP-based solution that can provide and support service differentiation in SDN optical networks is presented in [8].…”

“…MPTCP was proposed as an extension of TCP with the main idea of splitting a large flow into multiple subflows. The subflows originating from the same MPTCP connection are then sent to their destinations through different disjointed paths in the network [2]. MPTCP is a promising approach to improve performance and reliability of video streaming services in 5G networks.…”

The explosion of enhanced applications such as live video streaming, video gaming and Virtual Reality calls for efforts to optimize transport protocols to manage the increasing amount of data traffic on future 5G networks. Through bandwidth aggregation over multiple paths, the Multi-Path Transmission Control Protocol (MPTCP) can enhance the performance of network applications. MPTCP can split a large multimedia flow into subflows and apply a congestion control mechanism on each subflow. Segment Routing (SR), a promising source routing approach, has emerged to provide advanced packet forwarding over 5G networks. In this paper, we explore the utilization of MPTCP and SR in SDN-based networks to improve network resources utilization and end-user's QoE for delivering multimedia services over 5G networks. We propose a novel QoE-aware, SDN-based MPTCP/SR approach for service delivery. In order to demonstrate the feasibility of our approach, we implemented an intelligent QoE-centric Multipath Routing Algorithm (QoMRA) on an SDN source routing platform using Mininet and POX controller. We carried out experiments on Dynamic Adaptive video Steaming over HTTP (DASH) applications over various network conditions. The preliminary results show that, our QoEaware SDN-based MPTCP/SR scheme performs better compared to the conventional TCP approach in terms of throughput, link utilization and the end-user's QoE.

“…Another aspect to consider is that the development of the MP-TCP analyzer was proposed as part of a larger project that implements a solution for the shared bottleneck [8] that MP-TCP suffers. Details at bit level for MP-TCP were not offered by other available tools and these details were required for checking for compliance and reproducing the shared bottleneck.…”

MP-TCP (MultiPath-Transmission Control Protocol) is a network protocol that uses subflows for allowing the existence of disjoint paths and increases the overall throughput with respect to employing a common TCP connection. The idea of analyzing MP-TCP messages using the principles of SDN (Software Defined Networking) is proposed. Relevant aspects of how the Analyzer was developed as a module for OpenDayLight's SDN framework are presented. The Analyzer runs in the SDN controller and it commands the installation of appropriate rules in the network devices (switches supporting Openflow) so that all TCP traffic be derived to the controller. Then the Analyzer must identify MP-TCP messages by checking the options field of TCP and present all the related information to the user employing a GUI (Graphical User Interface). By combining the usage of proactive and reactive rules, the Analyzer's implementation tries to minimize the impact of sending TCP traffic to the controller. The Analyzer has been tested with other modules (e.g. Layer 2 Switch) that are included with OpenDayLight; this is done for showing that it is possible that the Analyzer may not interfere with other running modules. Some results obtained with the Analyzer when using physical and virtual switches in different topologies in a network using MP-TCP are presented. Simulation results using MP-TCP with Mininet are also discussed.

“…Different from our proposal, the proposed works are limited to TCP protocol and are a host‐centric approach. Works Li and Pan and Jinyao et al differ from our work since a flow is not split into subflows.…”

Analysis of monitoring and multipath support on top of OpenFlow specification

Summary In general, traffic is pushed through a single path despite the existence of alternative paths in networks. For example, routing solutions based on spanning tree prune the topology to prevent loops, consequently preventing also the use of alternative paths. Research on quality of service frequently advocates that the use of alternative paths is interesting for enforcing Service Level Agreements (SLAs), bypassing bottlenecks created by shortest paths. In this paper, we are interested in analyzing the support for monitoring network traffic and for provisioning of multipaths in software‐defined networking (SDN), given the strong platform it provides for experimentation of new networked solutions. Our approach firstly enriches the topology view at the control plane with data gathered through fine grain data plane monitoring. On the basis of such enriched view, our system determines the path, or multipaths, necessary to enforce the specified SLA. We propose 2 extension modules to an OpenFlow controller: SDNMon, which monitors the data plane to enrich the topology information at the control plane, and MP‐Routing, which determines a set of paths, in the absence of a single path capable of enforcing the SLA. Both modules are extensively evaluated, and the results not only demonstrate what can be achieved in terms of accuracy in SDNMon and in terms of quality of service benefits in MP‐Routing but also highlight some limitations of OpenFlow specification. On the basis of our findings, we propose a set of new counters to Per Port and Per Flow granularity levels of OpenFlow specification.
