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. Rosenberg Filename : draft-rosenberg-internet-waist-hourglass-00.txt Pages : 8 Date : 2008-02-11 One of the fundamental design principles of the Internet is that IP represents a common intermediate protocol layer, linking together a variety of link layer technologies underneath with a large number of applications on top. When drawn graphically, this can be show as an hourglass with IP in the middle. The preponderence of NATs and firewalls in the Internet has changed this reality, such that UDP and TCP are now the waist of the hourglass. This document discusses this change and describes its implications for protocol and application design.

Send a message to: mailserv@xxxxxxxxx In the body type: "FILE /internet-drafts/draft-rosenberg-internet-waist-hourglass-00.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. _______________________________________________ Ietf@xxxxxxxx http://www.ietf.org/mailman/listinfo/ietf
