Abstract

   This document describes a detailed model of IPv4 multicast with RSVP
   that has been developed using the OPNET simulation package [4], with
   protocol procedures defined in the C language.  The model was
   developed to allow investigation of performance constraints on
   routing but should have wide applicability in the Internet
   multicast/resource reservation community.  We are making this model
   publicly available with the intention that it can be used to provide
   expanded studies of resource-reserved multicasting.
