Hi everyone! I'm an academic at Rutgers University, New Jersey, USA. I've been interested in programmable networking research, defined in the broadest possible terms. I've done research on congestion control/transport before, and have background in both endpoint and in-network (router) scheduling. I've also been following Dave's (and others') cool work on router AQMs and debloating. Through the pandemic and after spending time in India (with some pretty bloated data networks, especially cellular), I've gained a visceral appreciation for low latency networking. These days I'm interested in transport and scheduling technologies, as well as novel options for connectivity (starlink included), that can help us end users to experience a better Internet in its all realtime glory. > One of our newer members is one of the authors of this: > > https://people.cs.rutgers.edu/~sn624/papers/ccp-sigcomm18.pdf > > I will reserve comment for now. I don't grok the intersection with ebpf as yet. Thanks for posting a pointer to this :) I'm happy to answer any questions about the work. -- Srinivas An adequate bootstrap is a contradiction in terms.
