Re: Core Based Tree(CBT) for ns

Hi, Paul

>From the current snapshot of ns2, under ~/tcl/mcast, there is a BST.tcl, 
which is a simple implementation of bi-direction multicast protocol. I 
think it is very similar to the functions of CBT, except the user has to 
explicitly define the variable RP($grp) to a particular node in your 
topology. There is also a example script file under tcl/ex/newmcast/mcast5.tcl,
you can take a look. Besides that, I am not aware any implementation of 
CBT in ns2 so far.
