	abstract = {Nowadays, cloud applications are becoming more and more popular. However, in order for such applications to work, they need a stable Internet connectivity. To avoid the Internet access becoming a single point of failure, redundancy by multi-homing -- i.e. simultaneous access to multiple Internet service providers (ISP) -- is becoming increasingly common as well. Multi-homing leads to the desire to utilise all network attachment points simultaneously, which is e.g. provided by the Multi-Path TCP (MPTCP) extension for TCP. MPTCP is still under development by researchers and standardisation in the IETF. Particularly, it is necessary to evaluate MPTCP under realistic Internet conditions. NorNet Core is the world\&$\#$39;s first, large-scale Internet testbed for multi-homed systems and applications. It is therefore a useful platform for evaluating MPTCP. In this paper, we therefore present our NorNet Core extension that adds MPTCP support to the testbed. Particularly, our extension is now available to all users of NorNet Core as well, which significantly reduces the effort of MPTCP researchers to evaluate MPTCP and its improvements. In a proof of concept, we furthermore show the strengths and weaknesses of state-of-the-art MPTCP in NorNet Core, in a configuration covering 29 ISP connections at 14 sites in 5 different countries.},

	abstract = {Multi-path transport has become a hot topic in Internet protocol research with the evolution of emerging technologies, particularly with the market penetration of access terminals having multiple network interfaces (e.g.\ smartphones with LTE/UMTS and Wi-Fi interfaces). Multi-Path TCP (MPTCP) is an extension of TCP that allows a connection to create several subflows for utilizing multiple network paths. Using multiple end-to-end TCP connections as subflows, MPTCP distributes data to different subflows over multiple ISPs, so as to enhance network robustness and improve throughput. This paper first presents MPTCP{\textquoteright}s architecture and multi-path congestion control algorithm concepts. Then, it examines three test scenarios in the NorNet testbed, particularly highlighting the performance difference between using uncoupled and coupled congestion controls in multi-homed, real-world Internet setups. The results show that MPTCP with coupled CCs gets more benefits than TCP and demonstrates the lower aggressiveness in comparison to MPTCP with uncoupled CCs.},
