Hi Alex,

Thank you very much for having caught this definition mismatch! I personally see TCP/IP as a network stack on its own right. From this perspective, XIA, TCP/IP, RDS, and TIPC are all at the same level as you concluded. I don't mind adopting the definitions that are more common among kernel developers.

Linux XIA is not replacing the other protocols (using your definition). Linux XIA is another protocol, and, as you correctly pointed out: a framework for other protocols.
