I did a basic implementation of PP that is still maintained in the NS2 
main code.
You fill find it if you look for PLM (Packet-pair Layered Multicast 
congestion control).

I don't remember is someone else has a PP code still maintained in NS2, 
and I am not
sure what I did is relevant to you. What I did is very simple: I send 
packets by pair (modifying a CBR
source) and at the receiver I simply compute the inter-packet arrival 
time to compute the available bandwidth
(here I am using a FQ queue). No magic here, and you will not see 
anything new compared to what was
described in the Keshav Ph.D. thesis.

Regards,
Arnaud.
