	Title		: Impairments And Other Constraints On Optical Layer Routing

Optical networking poses a number challenges for GMPLS. Optical 
technology is fundamentally an analog rather than digital technology; 
and the optical layer is lowest in the transport hierarchy and hence 
has an intimate relationship with the physical geography of the 
network.

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.
