Pollution in 1/8 (2010)

The RIS RRC from which we announced 1.1.1.0/24 has connections to AMS-IX , NL-IX and GN-IX. The above image shows the incoming traffic on the AMS-IX port, which was instantly maxed out, mostly by traffic coming towards 1.1.1.1. The outbound traffic is routed through the RIPE NCC networks and showed an increase of 5-6 MBit. The network run on the RRC is designed to collect BGP routing data rather than actually route any traffic. Although the AMS-IX port of the RRC was already maxed out by announcing 1.1.1.0/24, we still decided to do some traffic analysis. These measurements have to be taken with a grain of salt since we had no way of telling what kind of traffic was dropped before it could reach the RRC. For that reason we also decided not to include transfer rates in these measurements. To get an idea of the stability of the traffic pattern we collected 100,000 packets every 30 minutes over a period of 12 hours on 28 January 2010. Unless the traffic sent towards those blocks is significantly reduced they might be unusable in a production environment.
