A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: Payload-independent Delineation for Simple Data Link 
                          (SDL) Framing
	Author(s)	: P. Jha
	Filename	: draft-jha-optical-sdl-01.txt
	Pages		: 5
	Date		: 07-Mar-02
Simple Data Link (SDL) framing specification (rfc2823) defines a 
[length, length CRC] based construct with a tail-end payload CRC for 
delineating frames over digital links. Many protocols, however, 
already have built-in CRC mechanisms, and a tail-end CRC is not 
always needed. This draft proposes a modification to allow SDL 
receivers to delineate all types of payload without having to analyze 
payload protocol header to determine presence of CRC.

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

	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
