    Description of Working Group:

    Mobile IPv6 enables IPv6 mobile nodes to continue using a given "home
    address" in spite of changes in its point of attachment to the
    network. These changes may cause delay, packet loss, and also
    represent overhead traffic on the network. Previously the MIPSHOP WG
    worked on two technologies to address these issues. Hierarchical
    Mobile IPv6 (HMIPv6, RFC 4140) reduces the amount and latency of
    signaling between a MN, its Home Agent and one or more correspondent
    nodes. Fast Handovers for Mobile IPv6 (FMIPv6, RFC 4068) reduces
    packet loss by providing fast IP connectivity as soon as the mobile
    node establishes a new point of attachment at a new link.

    As part of its previous set of work items, MIPSHOP published these two
    protocols as experimental RFCs. Further implementation work by the
    community has increased the understanding of how FMIPv6 behaves or
    should behave on other link layers, and in general. Similarly, further
    implementation and experimentation with HMIPv6 has resulted in better
    understanding of the protocol. Accordingly, MIPSHOP will continue work
    on HMIPv6 and FMIPv6 and the necessary extensions in order to publish
    them as proposed standards.

    Additionally, the IEEE 802.21 Media Independent Handoff (MIH) working
    group aims at providing services to assist with handoffs between
    heterogeneous link-layer technologies, and across IP subnet
    boundaries. The information exchanges defined by IEEE 802.21 are
    classified as MI (Media Independent) Event Service (MIES), MI Command
    Service (MICS), and MI Information Service (MIIS). The MIIS provides
    topological and location-related information of service networks. The
    MIES provides timely communications of wireless environment
    information via the delivery of events originating across the
    link-layer or farther away. The MICS is an analogous service for
    commands which can change the state of the wireless link or of a
    host's point of attachment, potentially triggering further event
    generation. MIH services can be delivered through link-layer specific
    solutions and/or through a "layer 3 or above" protocol. MIPSHOP will
    define the delivery of information for MIH services for this latter
    case. Notice that this allows the network information to reside
    anywhere (not necessarily across the link-layer hop), and enables MIH
    services even in the absence of the corresponding link-layer support.
    An L3 based mechanism to identify a valid information server is also
    required. A liaison with IEEE 802.21 has been established, and access
    to the IEEE 802.21 drafts is granted to mipshop members. Interested
    members need to send a request to the WG chairs in order to obtain a
    copy of the current IEEE 802.21 draft.

    The MOBOPTS Research Group in the IRTF is chartered to work on
    optimizations related to Mobile IPv6 and IP handoffs among other
    things. The MIPSHOP WG will take mature proposals from the MOBOPTS
    group and standardize them in the IETF on a case-by-case basis. One
    such proposal on improving the Mobile IPv6 Return Routability
    procedure by reducing the round trip times required to complete the
    procedure, and increasing the length of time before the procedure
    needs to be run again, has already been taken up the MIPSHOP WG and
    stadardized.

    Scope of MIPSHOP:

    The working group will:

    1. Revise the specification of HMIPv6 (RFC 4140) protocol to advance
    it to Proposed Standard. This implies:

    * Define the use of IKEv2 for MN-MAP security
    * Streamline and refine the current HMIPv6 specification.
    Document: draft-ietf-mipshop-4140bis

    2. Revise the specification of FMIPv6 protocol (RFC 4068) to advance
    it to Proposed Standard.

    * Work on mobile node - access router security using both the AAA
    infrastructure, and keys derived from SeND
    Documents: draft-ietf-mipshop-handover-keys-aaa,
    draft-ietf-mipshop-handover-key
    * Streamline and refine the current FMIPv6 specification
    Document: draft-ietf-mipshop-fmipv6-rfc4068bis

    3. Work on the application of FMIPv6 on two examples link-layers for
    advancement as Informational RFCs:

    * IEEE 802.16e (and WiMax)
    * 3G CDMA 2K networks
    Documents: draft-ietf-mipshop-fh80216e, draft-ietf-mipshop-3gfh

    4. Work on areas of mutual interest to IEEE 802.21 and MIPSHOP:

    * Complete the problem statement, and a specification on transport
    of IEEE 802.21 services over IP.
    Documents: draft-ietf-mipshop-mis-ps (Problem Satement),
    draft-ietf-mipshop-mih-support (transport of 802.21
    services over IP, including security aspects)

    5. Standardize mature proposals from MOBOPTS Research Group.
    Adoption of specific proposals requires rechartering.
