IETF-standardized unicast transport protocols have been 
designed to allow two end points to maintain communications by 
individually reacting to loss or degraded packet arrival times. 
Historically, those protocols have assumed loss is congestive 
and have reacted by decreasing the packet transmission rate to 
ease congestion. There are a number of cases, however, where 
these assumptions are incorrect, and one or more path segments 
present losses due to intermittent connectivity, a high 
uncorrected error rate, or the need for access path changes 
('hand-off's). Previous work [PILC] has addressed these 
conditions using end-to-end mechanisms. This draft examines the 
use of an on-path signaling mechanisms capable of providing 
advisory notifications for use in modifying the behavior of the 
transport in order to better respond to actual network 
conditions.  This draft serves to create discussion in this area
as there are many ways to skin the cat. We are interested in 
hearing about them through open discussion.

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.
