The IESG has approved the following document: - 'IKEv2 Mobility and Multihoming Protocol (MOBIKE) ' <draft-ietf-mobike-protocol-08.txt> as a Proposed Standard This document is the product of the IKEv2 Mobility and Multihoming Working Group. The IESG contact persons are Russ Housley and Sam Hartman. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-mobike-protocol-08.txt Technical Summary This document describes MOBIKE, a mobility and multihoming extension to Internet Key Exchange (IKEv2). This protocol allows hosts to update the IP addresses associated with IKEv2 and tunnel mode IPsec Security Associations. A mobile VPN client could use MOBIKE to keep the connection with the VPN gateway active while moving from one address to another. Similarly, a multihomed host could use MOBIKE to move the traffic to a different interface if, for instance, the one currently being used stops working. Working Group Summary The document has been presented at several IETF WG meetings and been discussed extensively on the MOBIKE WG mail list. The document has been reviewed by a number of experts from different areas. The WG Last Call resulted in a fairly large number of issues, which indicates that many people took the time to review the document. Comment resolution resulted in few (maybe just one) changes that affects the on-the-wire protocol. All WG Last Call issues are addressed in the current version of the document. An issue tracker was used by the WG during design and protocol specification. There is consensus in the MOBIKE WG to publish this document as a proposed standard. Protocol Quality The basic concepts in MOBIKE are very straightforward. The hardest parts of the protocol involve the co-existence with IKEv2 NAT- Traversal features and the use of the IKEv2 communication channel for dynamically changing messages and addresses. Also, MOBIKE is only a part of an overall solution. For example, MOBIKE relies on the IP layer to detect when this node gets a new IP address. Contributors and reviewers include experts in IPsec, mobility, NAT traversal, and IKEv2 implementation. No known implementations exist at this time. MOBIKE is currently being referenced from one other IETF WG and one external SDO. This specification is part of the early RFC Editor copy editing experiment, and it has already gone through basic editing phase prior to WG Last Call. The specification authors used XML2RFC, which was a requirement for taking part in the experiment. This document was reviewed by Russ Housley for the IESG. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
