The IESG has approved the following document: - 'IEEE 802.21 Mobility Services Framework Design (MSFD) ' <draft-ietf-mipshop-mstp-solution-12.txt> as a Proposed Standard This document is the product of the Mobility for IP: Performance, Signaling and Handoff Optimization Working Group. The IESG contact persons are Jari Arkko and Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-mipshop-mstp-solution-12.txt Technical Summary This document describes a solution for discovering IEEE 802.21 Media Independent Handover (MIH) servers (called the MoS server) and a transport layer mechanism for the reliable delivery of MIH messages. Working Group Summary This is an output from the MIPSHOP WG. The MIPSHOP WG received numerous liaison statements from the IEEE 802.21 WG supporting this work. The solution described in the document is supposed to provide a Layer 3 protocol for transport of the handover assist information. The IEEE 802.21 WG also provided the requirements for the solution. Document Quality This specification has been reviewed by Jari Arkko for the IESG. There are no known implementations. Personnel Document shepherd: Vijay Devarapalli Responsible AD: Jari Arkko RFC Editor Note Please replace the first paragraph of Section 6.5 with this: The ES and CS messages are small in nature and have tight latency requirements. On the other hand, IS messages are more resilient in terms of latency constraints and some long IS messages could exceed the MTU of the path to the destination. TCP SHOULD be used as the default transport for all messages. However, UDP in combination with MIH acknowledgement SHOULD be used for transporting ES and CS messages that are shorter than or equal to the path MTU as described in Section 6.1. IESG Note Please add the following IESG note to the document: As described later in this specification, this protocol does not provide security mechanisms. In some deployment situations lower layer security services may be sufficient. Other situations require proprietary mechanisms or as yet incomplete standard mechanisms, such as the ones currently considered by IEEE. For these reasons, the specification recommends careful analysis before considering any deployment. The IESG emphasizes the importance of these recommendations. The IESG also notes that this specification deviates from the traditional IETF requirement that support for security in the open Internet environment is a mandatory part of any Standards Track protocol specification. An exception has been made for this specification, but this should not be taken to mean that other future specifications are free from this requirement. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
