multicast simulation on end-to-end behavior

[Shuqian Yan]

Hi,

I am simulating the end-to-end behvior between a source and receiver pair. I 
need to collect the statistics on the number of packets received by the 
particular receiver and the cumulative delay for the packets travel from the 
source to that receiver. Then I'll calculate the average delay from these data.

I tried several ways of doing it, but doesn't work out. 

Have anyone done this before? Pls enlighten me.

Tks.
