protocol extension to accelerate the mag s knowledge of the mn s multicast subscription after ho
Protocol extension to accelerate the MAG’s knowledge of the MN’s multicast subscription after HO
  • MAG entity in base solution relays on standard MLD procedures to get knowledge of MN multicast subscription after handover
  • Several delay sources contribute to increase the timing for multicast delivery at the new point of attachment
    • Delay due to the access to radio resources among competing MNs
    • Delay due to radio frame structure
    • Delay due to retransmissions caused by radio channel unreliability
    • Delay due to MLD message processing at MN
  • Solution proposal: to accelerate the MAG’s knowledge acquisition of the MN’s multicast subscription by means of new signaling messages internal to the network, decoupling subscription acquisition from
    • Underlaying radio technology
    • IGMP/MLD parametrisation tuning
    • PMIPv6 multicast architecture (current or evolved)
