Title : Layered Encapsulation of Congestion Notification
Author(s) : B. Briscoe
Filename : draft-ietf-tsvwg-ecn-tunnel-00.txt
Pages : 34
Date : 2008-10-16
This document redefines how the explicit congestion notification
(ECN) field of the outer IP header of a tunnel should be constructed.
It brings all IP in IP tunnels (v4 or v6) into line with the way
IPsec tunnels now construct the ECN field. It includes a thorough
analysis of the reasoning for this change and the implications. It
also gives guidelines on the encapsulation of IP congestion
notification by any outer header, whether encapsulated in an IP
tunnel or in a lower layer header. Following these guidelines should
help interworking, if the IETF or other standards bodies specify any
new encapsulation of congestion notification.
