What's URP? Sounds a little like UDP, is it a typo or something else?
I thought that might be a typo for UDP, but that doesn't have ACKs.
URP is
smaller, but if I remember well it does not handle out-of-order packets or packet
duplicates (both of which do not occur in a (virtual) line switched context).
Upon reflection, duplicates of course can occur when an ACK is lost.
