Subject: Protocol Action: Mobility Support in IPv6 to Proposed Standard
-------------


The IESG has approved the Internet-Draft 'Mobility Support in IPv6'
<draft-ietf-mobileip-ipv6-20.txt> as a Proposed Standard.  This
document is the product of the IP Routing for Wireless/Mobile Hosts
Working Group.  The IESG contact persons are Thomas Narten and Erik
Nordmark.
 
 
Technical Summary
 
      This document specifies the Mobile IP protocol for IPv6. Mobile IP
      allows a node to move around the internet, yet keep the same
      address while continue to communicate transparently with other
      nodes as it moves. Each mobile node is identified by its home
      address, regardless of its current point of attachment to the
      Internet. While situated away from its home, a mobile node is also
      associated with a care-of address, which provides information about
      the mobile node's current location. IPv6 packets addressed to a
      mobile node's home address are transparently routed to its care-of
      address. The protocol enables IPv6 nodes to cache the binding of a
      mobile node's home address with its care-of address, and to then
      send any packets destined for the mobile node directly to it at
      this care-of address.

      Mobile IP for IPv6 includes a route optimization mechanism that
      allows communicating nodes to forward packets directly to each
      other without having to relay all traffic via a Home Agent at the
      mobile node's home address. Route optimization can be invoked
      between arbitrary nodes without the need for some pre-existing
      shared security relationship. Route optimization uses a
      return-routablity procedure to verify the safety of performing
      route optimization.
       
Working Group Summary
 
  This document has been under very long development within the WG. It
  was brought to the IESG over a year ago, but was sent back to the WG
  in order to make changes to the security properties of route
  optimization. That led to the development of the return-routability
  mechanism.

  There is strong support for moving this document forward, and there
  continues to be frustration at the length of time this document has
  been under development.
 
Protocol Quality
 
  This document has been reviewed for the IESG by Thomas Narten.
