Abstract--With the increasing deployment of overlay networks, a mobile host with a range of network interfaces can be connected
 

Summary: Abstract--With the increasing deployment of overlay networks,
a mobile host with a range of network interfaces can be connected
to multiple access networks simultaneously. Such multihoming
technology can be exploited to distribute (or hand off) traffic
flows among the interfaces and access networks to achieve
seamless, robust and even quality-of-service-aware
communications for mobile hosts. At present, there is little
preexisting work that has sufficiently addressed the problem of
supporting both user- and network-initiated flow handoffs in a
unified architecture. In this paper, we propose a hybrid approach
to manage both kinds of handoffs in a flexible yet standardized
way by enhancing Mobile IPv6 (MIPv6) or its variant
Hierarchical MIPv6. Address management strategy in mobile
host multihoming context is investigated, and the corresponding
architectural and protocol choices are presented and analyzed.
Particularly, the proposed comprehensive handoff management is
described with signaling and operations highlighted.
Keywords--Flow handoff, Hierarchical Mobile IPv6, Mobile
