                        Mobility with ICE (MICE)
                   draft-wing-mmusic-ice-mobility-06

Abstract

   This specification describes how endpoint mobility can be achieved
   using ICE.  Two mechanisms are shown, one where both endpoints
   support MICE and another where only one endpoint supports MICE.
