RFC6224 - Base Deployment for Multicast Listener Support in Proxy Mobile IPv6 (PMIPv6) Domains

This document describes deployment options for activating multicast listener functions in Proxy Mobile IPv6 domains without modifying mobility and multicast protocol standards. Similar to home agents in Mobile IPv6, Local Mobility Anchors of Proxy Mobile IPv6 serve as multicast subscription anchor points, while Mobile Access Gateways provide Multicast Listener Discovery (MLD) proxy functions. In this scenario, mobile nodes remain agnostic of multicast mobility operations. Support for mobile multicast senders is outside the scope of this document. This document is not an Internet Standards Track specification; it is published for informational purposes.

RFC6636 - Tuning the Behavior of the Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) for Routers in Mobile and Wireless Networks

The Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the protocols used by hosts and multicast routers to exchange their IP multicast group memberships with each other. This document describes ways to achieve IGMPv3 and MLDv2 protocol optimization for mobility and aims to become a guideline for the tuning of IGMPv3/MLDv2 Queries, timers, and counter values. This document is not an Internet Standards Track specification; it is published for informational purposes.

RFC7028 - Multicast Mobility Routing Optimizations for Proxy Mobile IPv6

This document proposes some experimental enhancements to the base solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6) domain. These enhancements include the use of a multicast tree mobility anchor as the topological anchor point for multicast traffic, as well as a direct routing option where the Mobile Access Gateway can provide access to multicast content in the local network. The goal of these enhancements is to provide benefits such as reducing multicast traffic replication and supporting different PMIPv6 deployment scenarios.

RFC7161 - Proxy Mobile IPv6 (PMIPv6) Multicast Handover Optimization by the Subscription Information Acquisition through the LMA (SIAL)

This document specifies an experimental multicast handover optimization mechanism for Proxy Mobile IPv6 (PMIPv6) to accelerate the delivery of multicast traffic to mobile nodes after handovers. The mechanism, called Subscription Information Acquisition through the LMA (SIAL), is based on speeding up the acquisition of mobile nodes' multicast context by the mobile access gateways. To do that, extensions to the current PMIPv6 protocol are proposed. These extensions are not only applicable to the base solution for multicast support in Proxy Mobile IPv6, but they can also be applied to other solutions developed to avoid the tunnel convergence problem. Furthermore, these extensions are also independent of the role played by the mobile access gateway within the multicast network (acting as either multicast listener discovery proxy or multicast router).

RFC7287 - Mobile Multicast Sender Support in Proxy Mobile IPv6 (PMIPv6) Domains

Multicast communication can be enabled in Proxy Mobile IPv6 (PMIPv6) domains via the Local Mobility Anchors by deploying Multicast Listener Discovery (MLD) proxy functions at Mobile Access Gateways, by using direct traffic distribution within an ISP's access network, or by selective route optimization schemes. This document describes a base solution and an experimental protocol to support mobile multicast senders in PMIPv6 domains for all three scenarios. Protocol optimizations for synchronizing PMIPv6 with PIM, as well as a peering function for MLD proxies are defined. Mobile sources always remain agnostic of multicast mobility operations.

RFC7411 - Multicast Listener Extensions for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) Fast Handovers

Fast handover protocols for Mobile IPv6 (MIPv6) and Proxy Mobile IPv6 (PMIPv6) define mobility management procedures that support unicast communication at reduced handover latency. Fast handover base operations do not affect multicast communication and, hence, do not accelerate handover management for native multicast listeners. Many multicast applications like IPTV or conferencing, though, comprise delay-sensitive, real-time traffic and will benefit from fast handover completion. This document specifies extension of the Mobile IPv6 Fast Handovers (FMIPv6) and the Fast Handovers for Proxy Mobile IPv6 (PFMIPv6) protocols to include multicast traffic management in fast handover operations. This multicast support is provided first at the control plane by management of rapid context transfer between access routers and second at the data plane by optional fast traffic forwarding that may include buffering. An FMIPv6 access router indicates support for multicast using an updated Proxy Router Advertisements message format.

This document updates RFC 5568, "Mobile IPv6 Fast Handovers".
