If I receive some traffic at an IX peering router interface, I might want to know how I got it.

If it is a stream of bad traffic I might want to ask my upstream peer to help turn it off.

 

How do I find out who did send it to me?

If I capture a sample packet I could see the source MAC address.  Now I have to identify who owns the device with that MAC.

 

Is there any guidance from the IX operators on how to do this?

I'm sure phone calls to Ops teams are not cost effective or time efficient for anyone.

A common programmatic method across IXes would suit my use-case admirably.

 

I'd like to hear from anybody who either has a method in an IX, or who would like a method to exist.

 

Regards

Steve
