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).
