I am trying to simulate DiffServ in a wired-cum-wireless scenario+

using ns 2.35. I am using DiffServ with 1 physical and 3 virtual queues, also I would like to use the TokenBucket Policer

I have attached the TCL file here.

But when I run it I get the following error

[Tom@localhost DQS]$ ns topo.tcl

num_nodes is set 10

INITIALIZE THE LIST xListHead

Starting Simulation...

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_

highestAntennaZ_ = 1.5, distCST_ = 550.0

SORTING LISTS ...DONE!

ERROR: No Policy Table entry found for Source 2049-Destination 4194306.

Policy Table(3):

Flow (0 to 7): Token Bucket policer, initial code point 10, CIR 1000000.0 bps, CBS 3000.0 bytes.

Flow (1 to 9): Token Bucket policer, initial code point 11, CIR 1000000.0 bps, CBS 5000.0 bytes.

Flow (2 to 8): Token Bucket policer, initial code point 12, CIR 1000000.0 bps, CBS 10000.0 bytes.

The policy object doesn't exist, ERROR!!!

I cannot understand what is meant by "No Policy Table entry found for Source 2049-Destination 4194306" when I have only 3 sources that are node 0,1,2 and 3 destinations which are node 7,8,9 respectively.

Please Help

Thank You.
