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 / emails to Ops teams are not cost effective 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
