Draft of message to be sent after approval:
From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org>, mip6 mailing list <email@example.com>, mip6 chair <firstname.lastname@example.org> Subject: Protocol Action: 'Mobility Support in IPv6' to Proposed Standard The IESG has approved the following document: - 'Mobility Support in IPv6 ' <draft-ietf-mobileip-ipv6-25.txt> as a Proposed Standard This document is the product of the Mobility for IPv6 Working Group. The IESG contact persons are Thomas Narten and Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-mobileip-ipv6-25.txt
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 continuing 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. 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.
