use tbpoc-bfp shape ingress egress by ip

[micron10]

Hi compile tbpoc-bfp and now i whan to test to set speed to one of ips in network for down/up
please write example how to set this ?

Hi, sorry I'm not sure what you mean. Do you mean applying the token bucket to just a given IP address, or do you mean applying it to all IPs but with a different rate for one given IP address?

In both cases, you would have to check that your packets are IP, then compare the IP source or destination from IP header to that specific IP addess you want to process. And then, the rate to apply can be changed via the TB_TOKEN_NB and TB_TOKEN_REGEN constants in https://github.com/qmonnet/tbpoc-bpf/blob/master/tokenbucket.c.

I hope this helps?

Hi i have small network for test and use static/dhcp/pppoe service i have 3 services 1mb , 3mb, 5,mb and have 2 network: 192.168.20.0/24 lan anf 192.178.21.0/24 pppoe my idea is to set diff service for every ip in this pool 192.168.20.2 - 1mb 192.168.21.2 - 5mb

So you would have to filter on IP addresses, see how we get the source IP already. Compare the first three bytes of your IPs with the network prefixes you work with, and depending on the case, use the values associated to the desired rate.

The simplest way to have this would be to hardcode network prefixes and rates in your code. The “clean” way would be instead to pass them via a dedicated eBPF map.

please if have time make a sample to see how to set ip and speed

No sorry, I don't have time at the moment. You'll have to do your homework :)
