Stanford's John Ousterhout Pushes Homa as TCP Alternative for AI Data Centers
Stanford emeritus professor John Ousterhout promotes Homa, a message-based transport protocol that cuts short-message tail latency by 13x versus TCP in data center tests. Designed for AI workloads mixing tiny control messages with large flows, Homa uses receiver-driven grants and priority scheduling. It installs as a Linux kernel module alongside TCP.
A professor emeritus of Stanford drives Homa, a protocol that reorganizes network traffic and, according to his evidence, can significantly reduce the latency of short messages in data centers.
