FCAST: Object Delivery for the Asynchronous Layered Coding (ALC) and
NACK-Oriented Reliable Multicast (NORM) Protocols
Abstract
This document introduces the FCAST reliable object (e.g., file)
delivery application. It is designed to operate either on top of the
underlying Asynchronous Layered Coding (ALC) / Layered Coding
Transport (LCT) reliable multicast transport protocol or the NACK-
Oriented Reliable Multicast (NORM) transport protocol.
