I want to limit incoming traffic too, but in this case, the link goes slower and slower, but don't stay at specific speed. at filter, there is a "flowid :1", but, where is this class There isn't any class called ":1", right? I did read the lartc, but it's getting confused. If someone can help me, please send me an email. lucasmocellin@gmail.com Lucas. Hi,

This don’t work for me.

at filter, there is a “flowid :1″, but, where is this class There isn’t any class called “:1″, right?

I did read the lartc, but it’s getting confused.

So instead of a steady stream of packets coming at full speed, you get intervals of silence where the server is waiting for the previous packet to be acknowledged. In those intervals of silence things of higher priority can get a chance to come in.

There is no way to shape incoming packets. Albert, how you can ’shape’ packets which are already sent? There is no way to shape incoming packets.

There is something that I still don't get it. Is there a posibility to enqueue incoming traffic and how? I can see that the example limits the incoming traffic to a fixed rate. But how could I use a hierarchy of queues to do the job. I read the "Linux Advanced Routing & Traffic Control HOWTO" but I couldn't figured out how can I enqueue the incoming traffic. Thanks for the time. Hi There!! There is something that I still don’t get it. Is there a posibility to enqueue incoming traffic and how?

If someone wants to get deeper into details and get more control, they can always read the papers. That’s a good approach as it allows people to get some actual results quickly.

The folks that support the Linux Documentation Project are great, and it is through their work that I learned the differences between packet policing and packet shaping. I simply intended this post to serve as a quick howto on setting it up. I'm glad it helped.

Works flawlessly. I'd also like to report that this works fine throttling NAT'ed traffic from an ethernet interface to a VLAN interface. *VERY* useful considering I've found using tc to limit outgoing traffic on a VLAN interface does *not* work (unless my tests were wrong!).
