Implementation and assessment of Modern Host-based Multipath Solutions

Abstract
The Internet is changing: while devices used to be connected to the Internet through a single access link, we now see smart phones equipped with a wireless and a 3G interface, data-centres with many links between each machine, or company networks connected to several providers. Today, however, the available multiple links are not efficiently used. Smartphones can use only one access link at a time. Data-centres cannot fully utilise the available capacity of their many, expensive links. Company networks cannot route individual data flows through two providers simultaneously, for example to improve the end-user experience. Many research proposals have appeared in the last few years to overcome the above problems, in the form of new protocols, but in most cases they have not been implemented and their impact in real-world applications is not widely understood.
This thesis fills this gap by concentrating on two approaches, the Ipv6 host-based multihoming solution (Shim6) and Multipath TCP (MPTCP). We developed the first reference implementation of both protocols in the Linux kernel. Our efforts show that they can both be efficient and can co-exist elegantly with existing protocols and operating systems architectures.
We have measured the performance of both implementations. Our measurements indicate that MPTCP can significantly improve the performance of various environments including large data-centres such as Amazon EC2.
