Subject: N(R) and N(S)

Hello

from RFC 1795 (and 1434)I don't understand  if NS(R) and NR(S) must be 
moved in the data field of SSP info message as they are received from the 
station, or, discarded because they will be re-created by remote DLSw.
In the second case is not  clear how DLSw guarantees message 
sequencing on the TCP/IP net. Is this, for some reason, a no longer required 
function ?
It looks like I'm missing a chapter of the specs!

Thank you

The information frames carry only the I-field.  TCP is a reliable transport, unlike UDP (or IP), and assures ordering, no duplication, etc.  Therefore there is no need to include NS/NR, perform retries, etc.
