RFC6279 - Proxy Mobile IPv6 (PMIPv6) Localized Routing Problem Statement

Proxy Mobile IPv6 is the IETF Standard for network-based mobility management. In Proxy Mobile IPv6, mobile nodes are topologically anchored at a Local Mobility Anchor, which forwards all data for registered mobile nodes. The setup and maintenance of localized routing, which allows forwarding of data packets between two mobile nodes' Mobility Access Gateways without involvement of their Local Mobility Anchor in forwarding, is not considered. This document describes the problem space of localized routing in Proxy Mobile IPv6. This document is not an Internet Standards Track specification; it is published for informational purposes.

RFC6463 - Runtime Local Mobility Anchor (LMA) Assignment Support for Proxy Mobile IPv6

This document describes a runtime local mobility anchor assignment functionality and corresponding mobility options for Proxy Mobile IPv6. The runtime local mobility anchor assignment takes place during a Proxy Binding Update and a Proxy Binding Acknowledgement message exchange between a mobile access gateway and a local mobility anchor. The runtime local mobility anchor assignment functionality defined in this specification can be used, for example, for load- balancing purposes. [STANDARDS-TRACK]

RFC6572 - RADIUS Support for Proxy Mobile IPv6

This document defines new attributes to facilitate Proxy Mobile IPv6 operations using the RADIUS infrastructure. The protocol defined in this document uses RADIUS-based interfaces of the mobile access gateway and the local mobility anchor with the AAA server for authentication, authorization, and policy functions. The RADIUS interactions between the mobile access gateway and the RADIUS-based AAA server take place when the mobile node (MN) attaches, authenticates, and authorizes to a Proxy Mobile IPv6 domain. Furthermore, this document defines the RADIUS-based interface between the local mobility anchor and the AAA RADIUS server for authorizing received Proxy Binding Update messages for the mobile node's mobility session. In addition to the interactions related to mobility session setup, this document defines the baseline for the mobile access gateway and the local mobility anchor generated accounting. [STANDARDS-TRACK]

RFC6602 - Bulk Binding Update Support for Proxy Mobile IPv6

For extending the lifetime of a mobility session, the Proxy Mobile IPv6 specification requires the mobile access gateway to send a Proxy Binding Update message to the local mobility anchor on a per-session basis. In the absence of signaling semantics for performing operations with group-specific scope, this results in a significant amount of signaling traffic on a periodic basis between a given mobile access gateway and a local mobility anchor. This document defines optimizations to the binding update and revocation operations in Proxy Mobile IPv6 for performing operations with group-specific scope with the use of a group identifier. [STANDARDS-TRACK]

RFC6705 - Localized Routing for Proxy Mobile IPv6

Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol that enables IP mobility for a host without requiring its participation in any mobility-related signaling. PMIPv6 requires all communications to go through the local mobility anchor. As this can be suboptimal, Localized Routing (LR) allows Mobile Nodes (MNs) attached to the same or different Mobile Access Gateways (MAGs) to route traffic by using localized forwarding or a direct tunnel between the gateways. This document proposes initiation, utilization, and termination mechanisms for localized routing between mobile access gateways within a proxy mobile IPv6 domain. It defines two new signaling messages, Localized Routing Initiation (LRI) and Local Routing Acknowledgment (LRA), that are used to realize this mechanism. [STANDARDS-TRACK]

RFC6757 - Access Network Identifier (ANI) Option for Proxy Mobile IPv6

The local mobility anchor in a Proxy Mobile IPv6 (PMIPv6) domain is able to provide access-network- and access-operator-specific handling or policing of the mobile node traffic using information about the access network to which the mobile node is attached. This specification defines a mechanism and a related mobility option for carrying the access network identifier and the access operator identification information from the mobile access gateway to the local mobility anchor over Proxy Mobile IPv6. [STANDARDS-TRACK]

RFC6909 - IPv4 Traffic Offload Selector Option for Proxy Mobile IPv6

This specification defines a new mobility option, the IPv4 Traffic Offload Selector option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating IPv4 traffic offload policy for a mobility session. Based on the negotiated IPv4 traffic offload policy, a mobile access gateway can selectively offload some of the IPv4 traffic flows in the access network instead of tunneling back to the local mobility anchor in the home network.

RFC7077 - Update Notifications for Proxy Mobile IPv6

This document specifies protocol enhancements for allowing the local mobility anchor in a Proxy Mobile IPv6 domain to asynchronously notify the mobile access gateway about changes related to a mobility session. These Update Notification messages are exchanged using a new Mobility Header message type specifically designed for this purpose.

RFC7148 - Prefix Delegation Support for Proxy Mobile IPv6

This specification defines extensions to the Proxy Mobile IPv6 protocol for allowing a mobile router in a Proxy Mobile IPv6 domain to obtain IP prefixes for its attached mobile networks using DHCPv6 prefix delegation. Network-based mobility management support is provided for those delegated IP prefixes just as it is provided for the mobile node's home address. Even if the mobile router performs a handoff and changes its network point of attachment, mobility support is ensured for all the delegated IP prefixes and for all the IP nodes in the mobile network that use IP address configuration from those delegated IP prefixes.

RFC7222 - Quality-of-Service Option for Proxy Mobile IPv6

This specification defines a new mobility option, the Quality-of- Service (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node's IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the local mobility anchor and the mobile access gateway. Furthermore, making QoS parameters available on the mobile access gateway enables mapping of these parameters to QoS rules that are specific to the access technology and allows those rules to be enforced on the access network using access-technology-specific approaches.

RFC7389 - Separation of Control and User Plane for Proxy Mobile IPv6

This document specifies a method to split the control plane (CP) and user plane (UP) for a network infrastructure based on Proxy Mobile IPv6 (PMIPv6). Existing specifications allow a mobile access gateway (MAG) to separate its control and user plane using the Alternate Care-of Address mobility option for IPv6 or Alternate IPv4 Care-of Address option for IPv4. However, the current specification does not provide any mechanism allowing the local mobility anchor (LMA) to perform an analogous functional split. To remedy that shortcoming, this document specifies a mobility option enabling an LMA to provide an alternate LMA address to be used for the bidirectional user-plane traffic between the MAG and LMA. With this new option, an LMA will be able to use an IP address for its user plane that is different than the IP address used for the control plane.

RFC7458 - Extensible Authentication Protocol (EAP) Attributes for Wi-Fi Integration with the Evolved Packet Core

With Wi-Fi emerging as a crucial access network for mobile service providers, it has become important to provide functions commonly available in 3G and 4G networks in Wi-Fi access networks as well. Such functions include Access Point Name (APN) Selection, multiple Packet Data Network (PDN) connections, and seamless mobility between Wi-Fi and 3G/4G networks.

The EAP Authentication and Key Agreement (EAP-AKA), and EAP-AKA', protocol is required for mobile devices to access the mobile Evolved Packet Core (EPC) via Wi-Fi networks. This document defines a few new EAP attributes to enable the above-mentioned functions in such networks. The attributes are exchanged between a client (such as a Mobile Node (MN)) and its network counterpart (such as an Authentication, Authorization, and Accounting (AAA) server) in the service provider's infrastructure.

RFC7561 - Mapping Quality of Service (QoS) Procedures of Proxy Mobile IPv6 (PMIPv6) and WLAN

This document provides guidelines for achieving end-to-end Quality of Service (QoS) in a Proxy Mobile IPv6 (PMIPv6) domain where the access network is based on IEEE 802.11. RFC 7222 describes QoS negotiation between a Mobile Access Gateway (MAG) and Local Mobility Anchor (LMA) in a PMIPv6 mobility domain. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the MAG and LMA. IEEE 802.11 and Wi-Fi Multimedia - Admission Control (WMM-AC) describe methods for QoS negotiation between a Wi-Fi Station (MN in PMIPv6 terminology) and an Access Point. This document provides a mapping between the above two sets of QoS procedures and the associated QoS parameters. This document is intended to be used as a companion document to RFC 7222 to enable implementation of end-to-end QoS.

RFC7563 - Extensions to the Proxy Mobile IPv6 (PMIPv6) Access Network Identifier Option

The Access Network Identifier (ANI) mobility option was introduced in RFC 6757, "Access Network Identifier (ANI) Option for Proxy Mobile IPv6". This enables a Mobile Access Gateway (MAG) to convey identifiers like the network identifier, geolocation, and operator identifier. This specification extends the Access Network Identifier mobility option with sub-options to carry the civic location and the MAG group identifier. This specification also defines an ANI Update-Timer sub-option that determines when and how often the ANI option will be updated.

RFC7847 - Logical-Interface Support for IP Hosts with Multi-Access Support

A logical interface is a software semantic internal to the host operating system. This semantic is available in all popular operating systems and is used in various protocol implementations. Logical-interface support is required on the mobile node attached to a Proxy Mobile IPv6 domain for leveraging various network-based mobility management features such as inter-technology handoffs, multihoming, and flow mobility support. This document explains the operational details of the logical-interface construct and the specifics on how link-layer implementations hide the physical interfaces from the IP stack and from the network nodes on the attached access networks. Furthermore, this document identifies the applicability of this approach to various link-layer technologies and analyzes the issues around it when used in conjunction with various mobility management features.

RFC7864 - Proxy Mobile IPv6 Extensions to Support Flow Mobility

Proxy Mobile IPv6 (PMIPv6) allows a mobile node to connect to the same PMIPv6 domain through different interfaces. This document describes extensions to the PMIPv6 protocol that are required to support network-based flow mobility over multiple physical interfaces.

This document updates RFC 5213. The extensions described in this document consist of the operations performed by the local mobility anchor and the mobile access gateway to manage the prefixes assigned to the different interfaces of the mobile node, as well as how the forwarding policies are handled by the network to ensure consistent flow mobility management.
