Abstract-- In this paper we evaluate a spectrum of
various approaches to group communication for MIPv6
nodes: Network Layer Multicast (IP multicast), Applica-
tion Layer Multicast(ALM) and a hybrid approach. Based
on a previous comparison of the two extremes, we focus
on the hybrid solution and we propose a number of
optimizations. Our results show that although IP Multicast
is still the best option in terms of network performance,
due to deployment considerations, the hybrid approach is
a more attractive option.
