1. Introduction
1.1. Abbreviations
o TCP: Transmission Control Protocol
o MPTCP: Multi-Path TCP
1.2. Multi-Path TCP
The Multi-Path TCP (MPTCP) extension for the Transmission Control
Protocol (TCP) has been defined in [3], [4], [1], [2], [5]. There
are also detailed introductions provided for example by [8], [9] as
well as lots of further information material on [6]. MPTCP is
therefore not introduced in more detail here.
1.3. Scope
The scope of this document is to collect some experiences with the
usage of MPTCP in the NorNet testbed, a large-scale Internet testbed
for multi-homed systems.

2. Testbed Evaluation
2.1. The NorNet Testbed
The NorNet testbed (https://www.nntb.no) introduced in [11], [10] is
a programmable testbed platform with focus on the evaluation of
multi-homed systems. It consists of programmable nodes that are
distributed all over Norway as well as further locations in other
countries. NotNet is built and operated by the Simula Research
Laboratory and financed by Forskningsraedet (the Research Council of
Norway) through their INFRASTRUKTUR program (project number 208798/
F50).
NorNet has two main components: NorNet Core and NorNet Edge. NorNet
Core consists of currently 20 programmable sites
(https://www.nntb.no/pub/nornet-configuration/NorNetCore-Sites.html),
most of them multi-homed to several network providers. Details can
be found in [12], [14], [15] and [16]. NorNet Edge consists of
several hundreds of smaller nodes connected to all mobile broadband
providers in Norway (http://robustenett.no/map), details can be found
in [13]. Together, these two components offer a unique platform for
experimental networking research. NorNet is made available to the
international networking research community.
Further details on NorNet can be found on the NorNet website [17].
2.2. Multi-Path TCP in NorNet
The NorNet nodes are Linux-based and therefore run the Linux MPTCP
implementation by Universite catholique de Louvain-la-Neuve (see
[18]). With support by all NorNet Core nodes (circa 100 nodes at
currently 20 sites) and most NorNet Edge nodes (several hundreds),
NorNet probably provides the world's largest MPTCP experimentation
platform.
2.3. NetPerfMeter
NetPerfMeter [19], [7] is a network performance meter for the UDP,
TCP, MPTCP, SCTP and DCCP transport protocols over IPv4 and IPv6. It
simultaneously transmits bidirectional flows to an endpoint and
measures the resulting flow bandwidths and QoS. The results are
written as vector and scalar files. NetPerfMeter is provided in
NorNet to allow for transport protocol comparisons and transport
protocol performance evaluations.

3. Research Results and Work in Progress
So far, work has been done on evaluating MPTCP in the real-world
Internet. The following list is a short overview of current
research:
o [20] examines the different properties of 3G paths (UMTS as well
as CDMA2000) in NorNet Edge. These results provide an overview of
the QoS characteristics that can be expected by multi-path
transport protocols (and particularly by MPTCP) on different
paths.
o [21] analyzes the impact of buffer bloat on MPTCP connections over
mobile broadband (2G, 3G) and WLAN paths. Furthermore, it
proposes and evaluates Multi-Path Transport Bufferbloat Mitigation
(MPT-BM), a bufferbloat mitigation algorithm to improve MPTCP
performance in buffer-bloated wireless networks.
o [22] examines the performance benefits of multi-path transport
with MPTCP under heterogeneous wireless networks. It furthermore
introduces and evaluates the Dynamic Relative Path Scoring
(DRePaS) algorithm that optimizes the path management in such
setups.
o [23] examines the performance benefits of the state-of-the-art
Linux MPTCP implementation in a large-scale NorNet setup, covering
sites in multiple countries on different continents. It
particularly also shortly introduces the NetPerfMeter measurement
tool that is used to perform the measurements, and particularly
its extension for MPTCP.
o [24] examines how the IPv4/IPv6 identity duality can be utilized
with MPTCP in order to improve performance even in case of only a
single ISP connection.
4. Security Considerations
Security considerations on MPTCP are described in [3].
5. IANA Considerations
This document has no actions for IANA.
