Title : Multipath TCP

The Transmission Control Protocol (TCP) is used by the vast majority of applications to transport data reliably across the Internet. TCP was designed in the 1970s and has slowly evolved since then. Today's networks are multipath: mobile devices have multiple wireless interfaces, datacenters have many redundant paths between servers, and multihoming has become the norm for large server farms.
Meanwhile, TCP is essentially a single-path protocol: when a TCP connection is established, the connection is bound to the IP addresses of the two communicating hosts and these cannot change. Multipath TCP (MPTCP) is a major modification to TCP that allows multiple paths to be used simultaneously by a transport connection. We will first dsicuss the various use cases for Multipath TCP including smartphones, datacenters and IPv4/IPv6 coexistence. The design of Multipath TCP has been heavily influenced by the presence of middleboxes in the Internet. We will first discuss the hurdles that they impose on the evolution of transport protocols. Then we will discuss the main design decisions that have shaped Multipath TCP and briefly describe some of the main mechanisms included in the protocol. The talk will end with a discussion of several research challenges that remain open for Multipath TCP.

Olivier Bonaventure is Professor at Université Catholique de Louvain where he leads the IP Networking Lab. His research interests include Internet protocols, traffic engineering, routing, Internet measurements and network management. He is interested in both fundamental and applied research. His PhD students have developed several open-source software packages including the C-BGP simulator, OpenLISP and the shim6 and Multipath TCP implementations in the Linux kernel. He has published more than eighty papers in various scientific journals and conferences and has directed ten PhD thesis. He also contributes to the IETF and has been granted several patents.
Olivier Bonaventure received several awards as a researcher (Alcatel-Bell prize, INFOCOM 2007 best paper award, USENIX NSDI 2012 community award) and teacher (Wernaers prize for the development of online courses, prize for the open textbook Computer Networking : Principles, Protocols and Practice). He currently serves on the editorial board of IEEE/ACM Transactions on Networking, on the steering committee of ACM Conext, chairs the IEEE Internet award committee and is education Director of ACM SIGCOMM.
