Hello,
I have a question about QoS in JunOS (looking a replacement for CP).
I need to limit bandwidth for about a thousand PC-s to 256kbps each, in both directions. The limit must be enforced all the times, not only on congestion. PCs will reside behind one physical interface in a routed network.
I have successfully implemented policer and CoS based limits for 1 IP in the network (see attached txt), but stuck with the other 999 hosts..
As I understand, to limit the bandwidth for each client on the network i need 1000 different policiers or 1000 queues if I use CoS, please correct me If I'm wrong.
I found a possible solution for my problem in JunOS documentation:
http://www.juniper.net/techpubs/en_US/junos9.6/information-products/topic-collections/config-guide-policy/policy-configuring-multifield-classifiers-for-policing.html#id-11044236
family inet {
prefix-action per-source-policer {
policer 1Mbps-policer;
subnet-prefix-length 25;
source-prefix-length 32;
It would enable us to use one policier for each host.
But unfortunately prefix-actions are not supported on J-series and SRX routers except 3400+ (which is out of our budget) as I found out here:

If I think about realizing the same task in ScreenOS - the best solution I can think of, is 1000 policies with specific IP-s and traffic Shaping turned on on each of them. Which is not an elegant solution as well.
I would be grateful for any suggestions regarding this case,
Thanks in advance,
