This document describes the messages and procedures of the Negative-
acknowledgement (NACK) Oriented Reliable Multicast (NORM) protocol.
This protocol is designed to provide end-to-end reliable transport of
bulk data objects or streams over generic IP multicast routing and
forwarding services. NORM uses a selective, negative acknowledgement
mechanism for transport reliability and offers additional protocol
mechanisms to conduct reliable multicast sessions with limited 'a
priori' coordination among senders and receivers. A congestion
control scheme is specified to allow the NORM protocol fairly share
available network bandwidth with other transport protocols such as
Transmission Control Protocol (TCP). It is capable of operating with
both reciprocal multicast routing among senders and receivers and with
asymmetric connectivity (possibly a unicast return path) from the
senders to receivers. The protocol offers a number of features to
allow different types of applications or possibly other higher level
transport protocols to utilize its service in different ways. The
protocol leverages the use of FEC-based repair and other IETF reliable
multicast transport (RMT) building blocks in its design.

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.
