            DHCPv6 Extension for On Demand Mobility exposure
               draft-moses-dmm-dhcp-ondemand-mobility-05

Abstract

   Applications differ with respect to whether or not they need IP
   session continuity and/or IP address reachability.  Networks
   providing the same type of service to any mobile host and any
   application running on the host yields inefficiencies.  This document
   describes extensions to the DHCPv6 protocol to enable mobile hosts to
   indicate the required mobility service type associated with a
   requested IP prefix (or address), and networks to indicate the type
   of mobility service associated with the allocated IP prefix (or
   address) in return.

1.  Introduction

   [I-D.ietf-dmm-ondemand-mobility] defines different types of mobility-
   associated services provided by access networks to mobile hosts with
   regards to maintaining IPv6 prefix (or address) continuity after an
   event of the host moving to different locations with different points
   of attachments within the IP network topology.  It further specifies
   means for applications to convey to the IP stack in the mobile host,
   their requirements regarding these services.

   This document defines extensions to the DHCPv6 protocol ([RFC3315])
   in the form of a new DHCP option that specifies the type of mobility
   services associated with an IPv6 prefix (or address).  The IP stack
   in a mobile host uses the DHCP client to communicate the type of
   mobility service it wishes to receive from the network.  The DHCP
   server in the network uses this option to convey the type of service
   that is guaranteed with the assigned IPv6 prefix (or address) in
   return.

   This new option also extends the ability of mobile routers to specify
   desired mobility service in a request for IPv6 prefixes (as specified
   in [RFC3633]), and delegating routers to convey the type of mobility
   service that is committed with the allocated IPv6 prefixes in return.

   It is important to note that although this document specifies
