Programmable switches are a disruptive technology that has seen increasing adoption in the past decade. Since their inception, however, there has been tension regarding how to design these switches. Classic programmable switches operate at line rate but ...

Low Earth Orbit (LEO) satellite constellations are emerging as key to robust global internet connectivity, especially in areas that lack adequate terrestrial connectivity either due to lack of financial viability or due to disruptions caused by wars and ...

Networks are error-prone due to misconfigurations, and it is hard to identify the root causes in the configuration and find a repair due to the size and complexity of networks running distributed routing protocols. Thus, we advocate Automatic ...

Despite the superior performance of deep learning-based controllers in network applications, their practical adoption is limited due to the difficulty in understanding and trusting them. Existing explainability solutions largely focus on interpreting ...

Hyperscalers dominate the landscape of large network deployments, yet they rarely share data or insights about the challenges they face. In light of this supremacy, what problems can we find to solve in this space? We take an unconventional approach to ...

The Internet's success arose from classical layering: protocols like TCP and Ethernet can be independently understood, changed, debugged, verified, and offloaded to hardware using a clean service interface between layers. To accrue the same benefits at a ...

Network verification, broadly defined as proving the correctness of certain properties resulting from a network's configuration, cannot be efficiently solved on classical hardware via brute force. Prior work has developed a variety of methods that scale ...

The quest to build scalable data center networks has driven much of the innovation in the networking community in recent decades. But the one-size-fits-all service model offered by these networks does not meet the needs of every application. In response, ...

Rapid delay variations in today's access networks impair the QoE of low-latency, interactive applications, such as video conferencing. To tackle this problem, we propose Athena, a framework that correlates high-resolution measurements from Layer 1 to ...
