Talk Title:

The Host Network (and its implications to network protocols, OS and hardware)

Tuesday April 9, 2024

Bahen Centre for Information Technology, BA 3200

This lecture is open to the public. No registration is required, but space is limited.

Abstract:

The host network enables data transfers within hosts and forms the “last mile” for data transfers across hosts for distributed applications. This talk will reflect on my (ongoing) journey that started with a surprising phenomenon observed in a lab experiment—nanosecond-scale inefficiencies within the host network percolating through network protocols and OS to create millisecond-scale impact on distributed applications. I will discuss my work on understanding, characterizing, and resolving the above phenomenon in the lab and in production clusters. I will also discuss how this phenomenon opens up intriguing research questions at the intersection of computer networking, OS and architecture.
