Abstract

   This document was submitted to the IETF IPng area in response to RFC
   1550.  Publication of this document does not imply acceptance by the
   IPng area of any ideas expressed within.  Comments should be
   submitted to the  mailing list.

Executive Summary

   The Defense Modeling and Simulation community is a major user of
   packet networks and as such has a stake in the definition of IPng.
   This white paper summarizes the Distributed Interactive Simulation
   environment that is under development, with regard to its real-time
   nature, scope and magnitude of networking requirements.  The
   requirements for real-time response, multicasting, and resource
   reservation are set forth, based on our best current understanding of
   the future of Defense Modeling and Simulation.

1.  Introduction

   The Internet Engineering Task Force (IETF) is now in the process of
   designing the Next Generation Internet Protocol (IPng). IPng is
   expected to be a driving force in the future of commercial off-the-
   shelf (COTS) networking technology. It will have a major impact on
   what future networking technologies are widely available, cost
   effective, and multi-vendor interoperable.  Applications that have
   all of their network-layer requirements met by the standard features
   of IPng will be at a great advantage, whereas those that don't will
   have to rely on less-widely available and more costly protocols that
   may have limited interoperability with the ubiquitous IPng-based COTS
   products.
