Hi folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outpu...

Hi, I notice that if two or more existing connections match an ingress policing filter, the input bandwidth does not get evenly divided up between the n connections. Kinda like litters of baby animals, where the stronger babies get more access to the mothers teats and grow up bigger and faster than their siblings. The only workaround that''s working for me is t...

I would like to test police in ingress. I use kernel 2.4.20. I use this configuration: iptables -t mangle -A PREROUTING -i eth0 -s 10.31.12.2 -d 10.31.11.2 -p udp --dport 1001 -j MARK --set-mark 1 iptables -t mangle -A PREROUTING -i eth0 -s 10.31.12.2 -d 10.31.11.2 -p udp --dport 1002 -j MARK --set-mark 2 iptables -t mangle...

The OVS database in general specifies state, not actions. That is, if you set no ingress_policing_rate, then OVS takes that to mean that it sh...

Hello everybody on the list, I have the following situation where I want to police the speed of incoming packets from specific subnets to 1024kbps and then police all the rest to 256kbps, which is the speed my ISP grants for the rest of the internet. So, eth1 is the one connected to the cable modem and then to the internet. I do: tc qdisc add dev eth1 ingress handle ffff: t...

Hi. I''m using the following filter from lartc "ultimate PPP" example: tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 It works fine, but when I remove the "burst 10k", I receive the following error: "burst" requires "rate". Illegal "police" AFAIK, burst is how many bytes can be transferred over "rate" up to "ce...

Hi stef and all I want measure the policy perfomance for video traffic on mpls diffserv network. there are two different polices for video packet 1. Video packets that are marked that are over the limit are to be rejected at the edge router. 2. Video packets that are marked that are over the limit are to be downgraded as best effo...

Hi, I''m trying to police ingress traffic based on port numbers and IP addresses. The u32 match based on IP addresses seems to work without issues and I''m am able to police incoming packets. However, the same isn''t working with u32 matches based on TCP port numbers. For port numbers, I added exactly one &...

Hi, I''m trying to police the incoming traffic by using ingress qdisc,this is what I have in my script tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 4 \ handle 1: u32 divisor 1 tc filter add dev eth0 parent ffff: protocol ip prio 4 u32 \ match ip dport 40...

Hello, i try to use iptables to mark packet and then to filter them with tc. Here is my script: iptables -t mangle -A PREROUTING -s 172.28.54.41/32 -p tcp -j MARK --set-mark 1 tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 1 handle 1 fw police rate 10000kbit burst 10000kbit mtu 1500k drop flowid :1 I can not use u32 because i have several filter with more than one IP address in each. Packets seem to be well marked (command: iptables -t mangle -L -vnx) but packets are not filtered with tc. Can someone help me ? Thanks, Olivier. _...

I''m having trouble getting ingress policing to work on a bridged device. The bridge contains several interfaces: peth0, vif0.0, vif[1-7]0.1, vif[25].1 . (This is under xen, in case the vif''s didn''t give that away, so peth0 is renamed eth0.) The tc rules I have are: tc qdisc del dev peth0 root tc qdisc del dev peth0 in...

Hi all, I''d like to have multiple polices in an interface with different src address, like that: tc qdisc add dev eth4 handle ffff: ingress tc filter add dev eth4 parent ffff: protocol ip prio 5 u32 match ip src \ 192.168.18.0/24 police rate 128kbit burst 10k drop flowid :1 tc filter add dev eth4 parent ffff: protocol ip prio 5 u...

...ate-tc script ends with these ingress rules: ########## downlink ############# # slow downloads down to somewhat less than the real speed to prevent # queuing at our ISP.

Currently, linux tc has very useful concept of a ''index'' for a given policy. However, I need to have policers on multiple hosts to share the same index (and thus, know and police the aggregate traffic across a set of routers). I''d like to be able to share tc policers across a set of boxes. Unfortunately, I''m not knowledgeable enough myself to impleme...

Hi, I am trying to do some simple ingress limiting based on fwmark. I know the ability and sense to do INGRESS limiting is ehm... limited ;-) but still I want to try it. I tried several things. === 1 === tcq ingress handle ffff: tcf parent ffff: protocol ip prio 1 handle 1 fw police rate 12mbit burst 10k drop tcf parent ffff: protocol ip prio 1 handle 2 fw police rate 10mbit burst 10k drop tcf parent ffff: protocol ip prio 1 handle 3 fw police rate 1mbit burst 10k drop This installs OK, but the filters are never called. The netfilter stats show the marks are set though. To...

...in text: we connect to the internet via an ISP, where we also have an externally accessible host (host2). Internally we use NAT and several subnets. We have a 100Mbit/s connection to the ISP, but we only pay for 1Mbit/s. So in order to keep our traffic within the agreed parameters, we need to police our incoming and outgoing traffic. However the traffic from and to the ISP and host2 doesn''t have to be policed. For our external traffic there''s not much problem to shape the traffic in the egress queues (using HTB and TBF/SFQ stuff). This is well described in the LARTC howt...

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to
