IEEE had/has a tendency to publish without running code. CTIA/TIA/EIA has interim standards without runni= ng code, and had/has rules against even speaking about implementations. O= nly IETF expected/expects running code. An RFC is rarely issued before cod= ing. http://www.iana.org/assignments/tcp-parameters/ 253 N RFC3692-style Experiment 1 (*) [RFC4727] When my code is done, I'll post the completed draft and ask IANA for a non-experimental number. That's the usual process. My code shouldn't = go into an official release until we know that number. PS. Rumor has it that Cisco shipped a release with 254 in it. Let's no= t do that here. PPS. Adam used 255, not a correct official experimental number.
