         Mobility Capability Negotiation and Protocol Selection
                          draft-yan-dmm-man-04

Abstract

   Based on different requirements, multiple mobility management
   protocols have been developed.  Different protocols have different
   functional requirements on the network element or the host and then a
   scheme should be used in order to support the negotiation and
   selection of adopted mobility management protocol when a host
   accesses to a new network.  In this draft, this issue is analyzed.

1.  Introduction

   In order to clearly analyze the possible cases, the following
   category labels of the mobility management protocols are defined:

   o  Mobile IPv6 (MIPv6) protocol: the mobility management scheme based
      on [RFC6275].
   o  Proxy Mobile IPv6 (PMIPv6) protocol: the mobility management
      scheme based on [RFC5213].
   o  MIPv6 suit protocols: based on MIPv6, there are multiple extension
      protocols have been standardized.  These protocols can be
      classified into two types: protocols for the function extension
      and protocols for the performance enhancement.  The protocols for
      the function extension are proposed to support some specific
      scenarios or functions, such as Dual-stack Mobile IPv6 (DSMIPv6)
      [RFC5555] for mobility of the dual-stack nodes, Multiple Care-of-
      address (MCoA) [RFC5648] for hosts with multiple access interfaces
      and Network Mobility (NEMO) [RFC3963] for mobility of sub-network.
      The other type is proposed to enhance the performance of the
      mobility management, such as Fast Mobile IPv6 (FMIP6) [RFC5268]
      for fast handover, Hierarchical Mobile IPv6 (HMIPv6) [RFC5380] for
      hierarchical mobility optimization.  In the MIPv6 suit protocols,
      location update is initiated by the host and the tunnel is also
      terminated at the host.
   o  PMIPv6 suit protocols: in order to reduce the protocol cost and
      enhance the handover performance further, the network-based
