The 2 reference RFC's are about "Reliable Data Protocol"; it is not clear this is the same. If it is the same, then perhaps this page is titled wrong or needs to explain.

The Reliable Data Protocol article redirects here, fwiw. --Bobbozzo (talk) 21:28, 1 March 2009 (UTC)

Take a look at the link for draft-ietf-sigtran-reliable-udp-00.txt for the origins of the name of the protocol. However, the lead is wrong: RDP existed before Plan 9 was a twinkle and was developed by BBN not Bell Labs. There was an implementation of RDP in BSD that was dropped before BSD 4 that long predates Plan 9. Reliable UDP was developed largely by Cisco, 3Com and Ascend, loosely based on RDP, during the late 90's for use with SGCP and Q931+ (later to become MGCP and then finally MEGAGO). It was presented to the SIGTRAN working group in the draft mentioned above and was one of the protocols considered during initial attempts at developing MDP, a precursor to SCTP. Lucent's involvement likely started with their purchase of Ascend. RUDP still exists in commercial products today that were originally developed in 1999 and 2000, such as RAS boxes like 3com's Total Control Chassis, the RAS capable Cisco routers (e.g. 5400), and the Ascend TNT, although these implementations are likely incompatible. For newer commercial products, RUDP has been replaced by SCTP, SGCP, MGCP with MEGAGO/GCP/H.248, Q931+ with IUA, mostly inventions of the IETF SIGTRAN WG. — Dgtsyb (talk) 22:36, 1 March 2009 (UTC)
"Windowing and congestion control" mechanism were listed as one of the four main features that RUDP providing. However, this statement is against the description in the RELIABLE UDP PROTOCOL document:

RUDP does not profide any congestion control or slow start algorithms.

Moreover, the value of the "Maximum number of outstanding segments" which determines "the number of segments that should be sent without getting an acknowledgment" is "not a negotiable parameter" in RUDP. —Preceding unsigned comment added by Njupted (talkcontribs) 10:33, 7 November 2010 (UTC)
