             NSIS Protocol Operation in Mobile Environments

Abstract

   Mobility of an IP-based node affects routing paths, and as a result,
   can have a significant effect on the protocol operation and state
   management.  This document discusses the effects mobility can cause
   to the Next Steps in Signaling (NSIS) protocol suite, and shows how
   the NSIS protocols operate in different scenarios with mobility
   management protocols.
