TCP is criticized as being unsuitable for modern datacenters due to its fundamental flaws. The introduction of Homa as a new transport protocol aims to address these issues and unlock the full potential of modern networks. While not API-compatible with TCP, Homa shows promise for widespread usage by integrating with RPC frameworks. This suggests a shift towards a more efficient and effective protocol for datacenter communication. The controversial stance that TCP is fundamentally flawed and unfixable may surprise some, but the development of Homa provides a unique solution to this ongoing issue.
