Wave and Equation Based Rate Control provides rate and
congestion control for data delivery.  Wave and Equation Based
Rate Control is specifically designed to support protocols
using IP multicast.  It provides multiple-rate, congestion-
controlled delivery to receivers, i.e., different receivers
joined to the same session may be receiving packets at
different rates depending on the bandwidths of their
individual connections to the sender and on competing traffic
along these connections.  Wave and Equation Based Rate Control
requires no feedback from receivers to the sender, i.e., it is
a completely receiver-driven congestion control protocol.
Thus, it is designed to scale to potentially massive numbers
of receivers attached to a session from a single sender.
Furthermore, because each individual receiver adjusts to the
available bandwidth between the sender and that receiver,
there is the potential to deliver data to each individual
receiver at the fastest possible rate for that receiver, even
in a highly heterogeneous network architecture, using a single
sender.

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.
