In earlier posts on this topic (HOMA) we saw that TFA wants a new upper layer protocol to replace TCP and which is strictly a request/response protocol. They call that an RPC. RPC is a misnomer that invites all sorts of quibbling, so they would do better to not call it an RPC. New ULPs have trouble getting deployed due to bad middleboxen. It can work in a data center, but you have to deal with provisioning carefully when you opt to toss the congestion control belt and suspenders. More importantly, QUIC exists and is probably good enough, and without evidence that it's not I find HOMA and similar proposals to be possibly premature optimization.
