Great insights, and I would add that it’s not just the internet consumer side where there is pressure on TCP evolution, it’s in the datacenter, too. [1] [1] https://arxiv.org/abs/2210.00714

I highly recommend reading the original. https://arxiv.org/abs/2210.00714 For those who don't know Ousterhout created the first log structured filesystem and created TCL (used heavily in hardware verification but also forming the backbone of the some of the first large web servers: aolserver). I was actually surprised to find out he co-founded a company with the current CTO of Cloudflare. https://en.wikipedia.org/wiki/John_Ousterhout He has both a candidate replacement as well as benchmarks showing 40% performance improvements with…

This short paper answers this question and more. I found it a helpful explanation of specifically what TCP design problems Homa is intended to address. https://arxiv.org/abs/2210.00714
