  Distributed Mobility Management: Current Practices and Gap Analysis

Abstract

   This document analyzes deployment practices of existing IP mobility
   protocols in a distributed mobility management environment.  It then
   identifies existing limitations when compared to the requirements
   defined for a distributed mobility management solution.
