Traffic wasn't so overwhelmingly IP-based at the time that Frame Relay was designed. And even in the case of the IP traffic, quite a bit of it was and still is UDP-based. Also, I don't think the CCITT (ITU) really cared too much about what was riding above. The OSI layers dictate modularity. I doubt that answers your question, though! I hope someone else answers too. Also see one additional comment below. >With that out of the way, historically, why did the writers of frame-relay >include BECN as a method of congestion control when 1, it isn't end-to-end >as TCP is, and therefore not as "good" as TCP, and 2, End-to-end congestion control isn't necessarily better. Consider three regions: Region 1 Region 2 Region 2 If Region 2 experiences congestion and can notify Region 1 (and Region 1 can adjust), then Region 3 never experiences the congestion.
