[ns] how many agents attached to a node

[Sencun Zhu <szhu1@ise.gmu.edu>]

Hello, all:  
	
	when I attach 5 agents to a node, and all of them join in the
same multicast group, it works okay, but if I have more agents attached, 
then these agents will not be able to receive any data after join, 
I wonder if there is any limitation in this?   

BTW:  I am using Centralized Multicast.


thank you.
