Hi, Hannes, I can't answer for Jonathan, but I wondered the same thing, and decided that the answer was probably one of - "well, if we all know this, what are we doing differently now that we know it?", or - "the GOOD news is that the wasp waist-hourglass is no longer HTTP" [RFC3205], or - "the GREAT news is that the wasp waist-hourglass isn't Skype (yet)". Not sure which, of course :-) Thanks, Spencer, with apologies to Keith Moore [RFC3205} > Hi Jonathan, > Hi all, > > I read through the document and was not quite sure why you wrote it. > Everyone knows this already. > > Ciao > Hannes > > -------- Original Message -------- > Subject: I-D Action:draft-rosenberg-internet-waist-hourglass-00.txt > Date: Mon, 11 Feb 2008 19:30:01 -0800 (PST) > From: Internet-Drafts@xxxxxxxx > Reply-To: internet-drafts@xxxxxxxx > To: i-d-announce@xxxxxxxx > > > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > > Title : UDP and TCP as the New Waist of the Internet Hourglass > Author(s) : J.
