            DHCPv6 Extension for On Demand Mobility exposure
               draft-moses-dmm-dhcp-ondemand-mobility-08

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 and to allow networks to indicate the type of
   mobility service associated with the allocated IP prefix 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 continuity after an event of the
   host moving between 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])
   and [RFC3633] in the form of a new DHCP option that specifies the
   type of mobility services associated with an IPv6 prefix.  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 in return.
