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.

Group: 224.2.127.254, (SAP.MCAST.NET)
Source: 64.65.64.70 (hayakawa.lava.net)
Rate: 7 pps/24 kbps(1sec), 24 kbps(last 10 secs), 3 kbps(life avg)
Source: 81.194.43.1 (?)
Rate: 16711 pps/43716 kbps(1sec), 43716 kbps(last 30 secs), 32472 kbps(life avg)

whois -h whois.arin.net 64.65.64.70
[Querying whois.arin.net]

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

Group: 224.2.127.254, (SAP.MCAST.NET)

Source: 81.194.43.1 (?)

Rate: 16911 pps/44240 kbps(1sec), 44240 kbps(last 10 secs), 40484 kbps(life avg)

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?
