"Multipath TCP Congestion Control: from Theory to Implementation”

Thursday, December 3, 3:00 PM
STEPS 101

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 open-source 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.
