Mobility Capability Negotiation and Protocol Selection
draft-yan-dmm-man-06
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 and actual
requirement, 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
