Multipath TCP: analysis, design, and implementation
TL;DR: This work proposes a fluid model for a large class of MP-TCP algorithms and identifies design criteria that guarantee the existence, uniqueness, and stability of system equilibrium and motivates the algorithm Balia (balanced linked adaptation), which generalizes existing algorithms and strikes a good balance among TCP-friendliness, responsiveness, and window oscillation.
Proceedings ArticleDOI
Understanding host network stack overheads
TL;DR: In this article, the authors present measurement and insights for Linux kernel network stack performance for 100Gbps access link bandwidths and find that such high bandwidth links, coupled with relatively stagnant technology trends for other host resources (e.g., CPU speeds and capacity, cache sizes, NIC buffer sizes, etc.), mark a fundamental shift in host network stack bottlenecks.
Balanced Linked Adaptation Congestion Control Algorithm for MPTCP
TL;DR: The mechanism of Balia, the "Balanced linked adaptation", which is a congestion control algorithm for Multipath TCP (MPTCP), judiciously balances this tradeoff based on a new design framework that allows one to systematically explore the design space.
Proceedings ArticleDOI
Packet scheduling for Multipath TCP
Jaehyun Hwang,Joon Yoo +1 more
TL;DR: A new MPTCP packet scheduler is proposed that freezes the slow path temporarily when the delay difference between the slow and fast paths is significant, so that the small amount of data can be transmitted quickly via the fast path.
Proceedings ArticleDOI
IA-TCP: A rate based incast-avoidance algorithm for TCP in data center networks
TL;DR: This paper introduces a novel end-to-end congestion control algorithm called IA-TCP that avoids the TCP incast congestion problem effectively and validates that the algorithm is scalable in terms of the number of workers achieving enhanced goodput and zero timeouts.
