Model-Based Insights on the Performance, Fairness, and Stability of BBR
Google's BBR is the most prominent result of the recently revived quest for efficient, fair, and flexible congestion-control algorithms (CCAs). While the performance of BBR has been investigated...
Hummingbird: Fast, Flexible, and Fair Inter-Domain Bandwidth Reservations
To realize the long-standing vision of providing quality-of-service (QoS) guarantees on a public Internet, this paper introduces Hummingbird: a lightweight QoS-system that provides fine-grained...
An Axiomatic Perspective on the Performance Effects of End-Host Path Selection
In various contexts of networking research, end-host path selection has recently regained momentum as a design principle. While such path selection has the potential to increase performance and...
Enabling Novel Interconnection Agreements with Path-Aware Networking Architectures
Path-aware networks (PANs) are emerging as an intriguing new paradigm with the potential to significantly improve the dependability and efficiency of networks. However, the benefits of PANs can...
Incentivizing Stable Path Selection in Future Internet Architectures
By delegating path control to end-hosts, future Internet architectures offer flexibility for path selection. However, there is a concern that the distributed routing decisions by end-hosts, in...
GMA: A Pareto Optimal Distributed Resource-Allocation Algorithm
To address the rising demand for strong packet delivery guarantees in networking, we study a novel way to perform graph resource allocation. We first introduce allocation graphs, in which nodes...
Steelhead: Interleaving Partially Synchronous and Asynchronous Commit Rules on a Shared DAG
Dual-mode consensus protocols are fast when the network is partially synchronous and remain live under asynchrony. We introduce Steelhead, a dual-mode mechanism that composes a partially...
