Proxy Mobile IPv6
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
Network-based mobility management enables IP mobility for a host
without requiring its participation in any mobility-related
signaling. The network is responsible for managing IP mobility on
behalf of the host. The mobility entities in the network are
responsible for tracking the movements of the host and initiating the
required mobility signaling on its behalf. This specification
describes a network-based mobility management protocol and is
referred to as Proxy Mobile IPv6.
