This document presents the {\em Reliable Multicast Framing Protocol} (RMFP). RMFP is an ALF-based framework for protocols that can be integrated as {\em protocol profiles}. In this report two profiles are described: One for {\em Scalable Reliable Multicast} (SRM) and one for the {\em Local Group Concept} (LGC). Additionally to the specifications of RMFP and the profiles the report describes the design and implementation of an object-oriented RMFP link library. The implementation contains an API and a SRM (Scalable Reliable Multicast) profile. Other profiles are planned to follow. The key features of this implementation are the unified API to all protocol profiles implemented and a class interface to include implementations of new protocol profiles in an easy manner.
