Abstract

The base solution for providing continuous multicast service delivery in Proxy Mobile IPv6 (PMIPv6) domains is described in [RFC6224]. It specifies the basic functionality needed in the Proxy Mobile IPv6 [RFC5213] entities to provide a multicast service, so continuous delivery of multicast traffic is supported by obtaining, after each handover, the ongoing multicast subscription information directly from the Mobile Node (MN). When a mobile node attaches to a new Mobile Access Gateway (MAG), the mobile node is queried by the mobile access gateway through a Multicast Listener Discovery (MLD) General Query, which is sent just after any new link is set up, to learn of any existing subscription, as specified in [RFC2710] and [RFC3810].

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

Abstract

   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).
