Hey
I was wondering if you could use cbq to divide bandwidth into say 2
classes. Ie: divide a 100Mbit router into 80Mbits and 20Mbits,
Then implement priority queueing within the 20Mbit class, so that all
traffic from say one IP receives highest priority.
---------
|100Mbit|
| |
--------
/ \
/ \
/ \
-------- --------
|20Mbit| |80Mbit|
| | | |
-------- --------
|
|
\ /
priority
queueing
within
this class
All traffic from 192.168.4.0/24 goes through the 20Mbit class accomplished
with :
#Generate client 1 class queue
tc class add dev eth1 parent 10:1 classid 10:100 cbq \
bandwidth 100Mbit rate $CLIENT_1_BANDWIDTH allot 1514 weight \
$CLIENT_1_PRIO prio 5 maxburst 20 avpkt 1000 bounded
#Manage client class queue 1
tc qdisc add dev eth1 parent 10:100 sfq quantum 1514b perturb 15
192.168.4.3/32 must receive higher priority for video conferencing say,
# If not mistaken this marks the packets to be filtered?
# It does not actually give traffic to this IP preferred handling does it?
tc filter add dev eth1 parent 10:100 protocol ip prio 0 u32 match ip dst
192.168.4.3/32 flowid 10:150
If someone could be so kind as to help me out that would be great!
Or must I create a new root class to implement the priority queueing
for the prefered IP.
Warmest reguards,
Al
