[Click] Read write handler question on roofnet with click

[Rajesh Prasad]

Hi ,
I am a Phd Candidate working on a protocol similar to "XORs in The Air: 
Practical Wireless Network Coding". I have been working on the CLICK 
modular router and roofnet software for some time. I have the software 
running in simple Alice-Router-Bob configuration. I want to extend it to 
5 computers in a cross configuration with router at the center of the 
cross.

1)Can you please give some direction how the write handler passes the 
parameter( written below) to roofnet (where are these parameter stored 
to be used by roofnet). I looked into the srcr code and could not 
determine how they are used.

srcr/sendmgr.max_xmits 1
srcr/arp.insert 5.191.186.212 00:11:95:BF:BA:D4
srcr/set_sr.set_route 5.137.112.229 5.22.131.89


2)For roofnet to function do I have to set srcr/arp of all laptops in 
each computer?

3)If I have five computer A,B,C,D in a cross topology with router at the 
center of the cross. If I have a cross flow from "A" and "B" sending 
packet to each other via router, similarly "C" and "D" send to each 
other via the router...  how do I set the  srcr/set route  on each of 
the computer?

4)If instead of udpencap I want tcp flow how do do I pass the write 
handler?
       writehandler.pl  udpencap.flow Alice 3456  Bob  3457 (eg how I 
use the udp)

I know they are very simple question but I could not find any help thats 
why I am writing to the forum.Thanking any help in advance
