Seminar Title: Multipath TCP Congestion Control: From Theory to Implementation

Speaker: Anwar Walid

Affiliation: Mathematics of Networks and Systems Research Department, Bell Labs

Abstract: 

Multipath TCP (MPTCP), an experimental IETF standard, has the potential to significantly improve application performance by transparently taking advantage of the increasingly available multiple network paths and multiple interfaces on user devices. In this talk we describe our recent research on MPTCP congestion control, which spans control theory and open-source implementation. We describe our “Balia” congestion control algorithm, a key feature of the new v0.90 release of MPTCP Linux Kernel implementation, and review the theory behind its design that enables it to optimize performance tradeoffs. We highlight applications in wireless 5G, data centers and SDN-enabled networks. Ongoing research directions will also be discussed.
