I am a computer scientist interested in everything networked: from protocols and applications to the hardware that carries our data across the Internet. My goal is to make networks faster, more reliable, more secure, and lately, more fair and equitable.

This week, Facebook suffered an all-day outage due to errors in their BGP and DNS configuration. I spoke to Charlotte Hu of Popular Science about what went wrong and why increasing centralization of Internet services makes us more prone to such catastrophic failures. Read more here.

Kernel bypass approaches to networking provide very high throughput and low latency, at the cost of ease of administration. Operators lose many debugging, management, and scheduling tools that OS kernels typically offer when packets bypass the kernel altogether. At HotOSXVIII today, Hugo Sadok suggests that we might be able to keep both manageability and high performance by implementing an OS interposition layer on FPGA-based SmartNICs. Read the paper and watch the talk to learn more.
