Homa protocol replaces TCP for high-performance AI cluster networking
October 4, 2026
Homa utilizes receiver-driven flow control to minimize tail latency in data center networks. It replaces traditional TCP-based congestion control with a system that manages packet scheduling at the receiver, addressing the incast problem common in distributed training workloads.
