Stef,
Traffic Control is not taking place after applying the above rules. Here 
follows the test setup:-
1. The linux m/c 's eth0(100Mbits, WAN) is connected to 128 Kbits ADSL 
and eth1 to the LAN.
2.  I tried doing traffic control for incoming(at eth1) and outgoing(at 
eth0) traffic using CBQ(above rules).
3.  In LAN, I connected 3 m/c's(all linux).
4.  The ISP rate  taken is 97% of 128Kbits.
5.  Bandwidth Monitoring is done by using IPTraf on each LAN m/c's.

I have few observations and queries, as follows:--
1. Here the ISP rate is fluctuating in the range of 21Kbits to 131 Kbits 
for 128Kbits ADSL.
2. I have not added any filter for the parent class. Is it required...? 
What happens if I add...?
3. Is "iptraf " tool OK for monitoring the distribution of bandwidth on 
each LAN m/c.
4. Whether shall I take outgoing and incoming ISP rate's in 30:70 ratio, 
i.e 30% if 128Kbits for outgoing Qdisc(eth0) and 70% for incoming
    Qdisc(eth1). As 128 Kbits rate being asyncronous(ADSL).

Can you pls guide me where amI going wrong..?
