Another sap storm seems to have shown up recently, with a different source than previously advertised. Both the packet and bit rate appear to be pretty interesting.

Here is what we’re seeing from Universite Paris. Do the high pps and kbps rates indicate that maybe they are accidently trying to source video/audio on the SAP group? We aren’t seeing any performance issues here just a little uptick in traffic.

sh ip mroute active

Active IP Multicast Sources - sending >= 4 kbps

a negative (-) Rate counts pps being fast-dropped

We just got hit with a SAP storm from 81.194.43.1. ARIN reports that this is someone from the RIPE network. Anyone else see this?
