I'm currently working on a tool to do this.  For now, it takes the output of 
tc and generates three grahs for each qdisc/class : packet/s, byes/s, size of 
packets.  It's not real-time (runs from crontab each 5 minutes) to collect 
the data and creates the images on the fly.
I also want to parse the output from iptables so you can make graphs of all 
traffic you want.  I also searched for a script to view this graphs in real 
time, but I have no idea to do this :-(.  I wrote a perl script that 
generates somthing in html, but it looks awfull.  It uses the output of 
iptables.  You can find this all on www.docum.org (graphs under GUI and 
realtime monitor under monitor.pl).  I really want to create something 
usefull and any help is appreciated.

You can use a dedicated box to shape the traffic and place it between the 
link and the network.

'iptraf' and 'trafshow' can help.

You can use the ingress policer with the right u32 filters to achieve this.

[LARTC] traffic monitoring: help regarding

[Project Work]

Hello,
   We are doing a project on bandwidth management.  We are controlling the 
outgoing bandwidth using HTB.  Currently we are viewing the traffic rate 
using tc.  We want to extract the rate of the traffic, the number of packets 
and then display on our interface in real time (traffic monitoring).  We 
also want to control the incoming bandwidth based on IP, Protocol etc.  
Could you please suggest ways for doing these.

Regards,
  Viswanath, Pramod, Leetha.
