Experiences with MPTCP in an intercontinental OpenFlow network

چکیده
The size and amount of e-science data sets is growing rapidly. Keeping up with the network demand in order to transfer these data sets over the Internet is a challenge. Single links do not have enough capacity anymore. Therefore we need to install more interfaces in the servers and use all available paths in the network. In this paper we describe two new technologies that help to optimally use the capacity of all multiple paths simultaneously. OpenFlow is used to discover the topology of the network, calculate multiple paths and configure those paths on the OpenFlow network. Multipath TCP (MPTCP) is used on the servers to distribute the load across the paths. We describe the end-to-end goodput measurements we did in our OpenFlow testbed. We show that we reach a much higher throughput with multiple paths compared to a single path.

A Simple Multipath OpenFlow Controller using topology-based algorithm for Multipath TCP
Multipath TCP, or MPTCP, is a widely-researched mechanism that allows a single application-level connection to be split to more than one TCP stream, and consequently more than one network interface, as opposed to the traditional TCP/IP model. Being a transport layer protocol, MPTCP can easily interact between the application using it and the network supporting it. However, MPTCP does not have c...

In order to satisfy the high bandwidth and performance demands of applications, host servers are built with multiple network interfaces, and a data center network consists of multiple redundant links. It is important to make efficient use of all the available network capacity, using multiple physical paths whenever possible, but traditional forwarding mechanisms using a single path are not able...

Operating unprotected network links for international collaboration between research and education communities, subject to a high-availability production service requirement, is challenging. Provisioning circuits, maintaining a loop-free network topology, and configuring multi-path redundancy to provide high availability are complex processes, which involve extensive coordination between, and m...
متن کاملEvaluating Multipath TCP Resilience against Link Failures
Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...
متن کاملAutomating the Testing of OpenFlow Applications
Software-defined networking, and the emergence of OpenFlow-capable switches, enables a wide range of new network functionality. However, enhanced programmability inevitably leads to more software faults (or bugs). We believe that tools for testing OpenFlow programs are critical to the success of the new technology. However, the way OpenFlow applications interact with the data plane raises sever...
