3048: Reliable Multicast Transport Building Blocks for One-to-Many Bulk-Data Transfer.

This document describes a framework for the standardization of bulk- data reliable multicast transport. It builds upon the experience gained during the deployment of several classes of contemporary reliable multicast transport, and attempts to pull out the commonalities between these classes of protocols into a number of building blocks. To that end, this document recommends that certain components that are common to multiple protocol classes be standardized as "building blocks". The remaining parts of the protocols, consisting of highly protocol specific, tightly intertwined functions, shall be designated as "protocol cores". Thus, each protocol can then be constructed by merging a "protocol core" with a number of "building blocks" which can be re-used across multiple protocols.
