A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiparty Multimedia Session Control Working Group of the IETF.

	Title		: A Transport Independent Bandwidth Modifier for the 
                          Session Description Protocol (SDP)

The existing Session Description Protocol (SDP) bandwidth modifiers
and their values include the bandwidth needed also for the transport
and IP layers. When using SDP in protocols like Session Announcement
Protocol (SAP), Session Initiation Protocol (SIP) and Real-Time
Streaming Protocol (RTSP) and the involved hosts reside in networks
running different IP versions, the interpretation of what type of
lower layers that is included is not clear. This documents defines a
bandwidth modifier that does not include transport overhead, instead
an additional packet rate attribute is defined. The transport
independent bit-rate value together with the packet rate can then be
used to calculate the real bit-rate over the actually used transport.

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.
