So RDP is a useful and deployed pre-standards protocol that was one of the driving forces behind a successful standardization effort. But newer applications that need that kind of transport instead use the standard, SCTP. I don't know how one could possibly make a stronger case for classifying the RDP spec as Historic! However, I do agree with John Klensin's remark that reclassification is not worth the energy it takes. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
