Ns forwarding support for multicast shared tree arquitectures

[Guillermo Rigotti <grigotti@exa.unicen.edu.ar>]

Hi,

Ns support for multicast forwarding (multiclassifier + replicators) is
source based oriented: a replicator is created for each pair <src,
group> , resulting in an innecessary simulation overhead when simulating
shared tree protocols such as CBT (in such case  is necessary create
only one replicator for multicast group -and for each input interface).
Is there any work to implement Ns support for both, source based and
shared tree architectures?
