Senior Researcher

Palo Alto, CA, US

I am a networking researcher focusing on making networks operator friendly.

My research revisits fundamental design assumptions made in widely-deployed networks with a goal of improving their operational and deployment complexity. Ongoing projects include:
  • Towards reliable and predictable Ethernet network stacks with Gazelle. This work revisits foundational design assumptions baked into end-host network stacks and their interactions with the network fabric with the lens of removing ambiguity around application errors that can be traced back to networks. Our work on How to diagnose nanosecond network latencies in rich end-host stacks is being presented at NSDI 2022.
  • Towards manageable networks with Netivus. This work revisits fundamental design assumptions baked into tcp/ip network models employed by network vendors with the lens of simplifying network deployment and operations for network owners. Our work on Understanding Lifecycle Management Complexity of Datacenter Topologies won the best paper award in NSDI 2019.
