	Title		: Reliable Multicast Transport Building Block:Tree based
                          ACK (TRACK) Mechanisms

The Reliable Multicast Transport (RMT) Working Group has been 
chartered to standardize reliable multicast transport services and 
protocol instantiations, which include the tree-based ACK (TRACK) 
protocol. This document describes the RMT Building Block for Tree-
based ACK (TRACK) mechanisms.  It contains functions relating to 
positive acknowledgments and hierarchical tree construction and 
maintenance.  It might primarily be used as part of the TRACK 
Protocol Instantiation. According to the charter, a building block 
is 'a coarse-grained modular component that is common to multiple 
protocols along with abstract APIs that define a building block's 
access methods and their arguments.' The TRACK BB mechanisms will 
operate on the logical ACK-tree that is configured by the TREE BB 
[10] in the TRACK PI sessions. This document is made based on the 
guidelines for the RMT BB [5].

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.
