It's using TCP (standard sliding window algorithm) to ensure reliability.

The interesting question is what *additional* reliability guarantees 
does AMQP (or, as a matter of fact, by any other messaging protocol) 
provide on top of TCP. That's a question that's bugging me for years and 
I haven't found an answer yet.

IIRC I've asked it during the "message broker websocket subsprotocol" 
IETF discussion with Mark Hapner (author of JMS) and Clebert Suconic 
(current HornetQ project lead) but never got an answer.

Anyway, I think we've strayed pretty far away from the intended topic of 
this mailing list.
