Observing real Multipath TCP traffic
Computer Communications, 2016Co-Authors: Viet Hoang Tran, Benjamin Hesmans, Quentin De Coninck, Ramin Sadre, Olivier BonaventureAbstract:We analyse a Multipath TCP dataset collected from Multipath-tcp.org consecutively in 5 months.Multipath TCP correctly passes through a wide range of Internet paths.Current implementations of Multipath TCP try to utilise additional paths as quickly as possible.Multipath TCP could be further improved in terms of traffic overhead and path management. Multipath TCP is a recent TCP extension that enables multihomed hosts like smartphones to send and receive data over multiple interfaces. Despite the growing interest in this new extension, little is known about its behavior in real networks. We analyze a five-month trace collected on Multipath-tcp.org using Multipath TCP. This first detailed study of real Multipath TCP traffic reveals several interesting points about its behavior in the wild. With packets from thousands of hosts using IPv4 and/or IPv6, we confirm that Multipath TCP correctly passes through a wide range of Internet paths. We observe long Multipath TCP connections that benefit from handovers and also connections composed of subflows having very different round-trip-times. We also analyze some inefficiencies in the current Multipath TCP implementations and quantify the importance of reinjections, i.e. the transmission of the same data over two or more subflows.

AIMS - Measuring and Modeling Multipath TCP
Intelligent Mechanisms for Network Configuration and Security, 2015Co-Authors: Viet Hoang Tran, Ramin Sadre, Olivier BonaventureAbstract:Multipath TCP, a major extension to regular TCP, allows TCP clients to utilize multiple paths to improve the transfer rate and connection robustness. Providing these benefits without requiring to upgrade network infrastructure nor applications, Multipath TCP is becoming more popular. Notably Apple iOS 7 now supports it for SIRI. However, there is still lack of a complete understanding of Multipath TCP in practice. How much can a user benefit from Multipath TCP in different scenarios? Which factors affect the performance of Multipath TCP? How well can we predict the behavior of Multipath TCP in a specific environment? Our research aims to answer these questions by large-scale measurements and model-based analysis. The answers will be an important input for designers and developers to further improve Multipath TCP.

Tracing Multipath TCP connections
Proceedings of the 2014 ACM conference on SIGCOMM - SIGCOMM '14, 2014Co-Authors: Benjamin Hesmans, Olivier BonaventureAbstract:Multipath TCP [2] is a major extension to the TCP proto- col. Multipath TCP enables a host to send packets belonging to one connection over different interfaces and IP addresses. This is a major change to TCP where one connection is always bound to one four-tuple (source and destination ad- dresses and ports). To understand the basics of Multipath TCP, let us consider the simple and important use case of a smartphone1 using WiFi and 3G to connect to a server. To start aMultipath TCP connection, the smartphone initiates a three-way handshake with the server over the 3G inter- face. This handshake includes specific options to negotiate the utilisation of Multipath TCP. Once this TCP connec- tion has been established, it becomes the first subflow of the Multipath TCP connection. To use the WiFi interface, the smartphone starts another three-way handshake over this interfaces and indicates that TCP connection is the second subflow of the Multipath TCP connection. The number of subflows associated to one Multipath TCP connection can vary over time.

Congestion Control Design for Multipath Transport Protocols: A Survey
IEEE Communications Surveys and Tutorials, 2016Co-Authors: Changqiao Xu, Jia Zhao, Gabriel-miro MunteanAbstract:High-quality services over wired and wireless networks require high bitrate network content delivery. Multipath transport protocols utilize multiple paths to support increased throughput for network applications. Ubiquitous mobile devices with multiple interfaces such as WiFi and 4G/5G cellular, and data centers supporting big data analysis and cloud-computing motivate adoption of Multipath transmission in current and future network architectures. Congestion control mechanisms play a fundamental role in these Multipath transport protocols. Diverse approaches have been proposed in the literature, differing in terms of their goals, principles, performance and mostly in how various issues are addressed in their design. This paper presents a survey of congestion control solutions for Multipath transport protocols and discusses the Multipath congestion control design in order to address the need for some desirable properties including TCP-friendliness, load-balancing, stability and Paretooptimality. Existing window-based and rate-based Multipath congestion control algorithms are investigated and categorized based on their theoretical algorithm design. Next the article discusses the congestion control mechanisms used in diverse Multipath transport protocols in the context of different network scenarios. Finally, the trends in the future Multipath congestion control design are presented.

review survey of Multipath routing protocols for mobile ad hoc networks
Journal of Network and Computer Applications, 2009Co-Authors: Mohammed Tarique, Kemal E Tepe, Sasan Adibi, Shervin ErfaniAbstract:This survey investigates Multipath routing protocols for mobile ad hoc networks (MANETs). The main objectives of Multipath routing protocols are to provide reliable communication and to ensure load balancing as well as to improve quality of service (QoS) of MANETs. These Multipath protocols are broadly classified into five categories based on their major goals. The goals are to improve delay, provide reliability, reduce overhead, maximize network life and support hybrid routing. Multipath routing protocols address issues such as multiple paths discovery and maintaining these paths. Issues, objectives, performances, advantages and disadvantages of these protocols are investigated and summarized. A checklist is provided as a guideline so that a network designer can choose an appropriate Multipath routing protocol to meet the network's application objectives.
