It would be helpful if you could reply on list, no point this being left up in the air. I know there are people on this list who represent Arbor also, It would be good to get a response to the figures mentioned?<br>

Dear Roland<br>
<br>
I've been doing a bit of research on DDoS attacks lately and have been looking at information presented by both Arbor and Prolexic<br>
<br>
Prolexic says Q1 2013 the average attack from last quarter has increased from 5.9Gbps to 48.25Gbps with an average packet per second rate of 32.4 million packets.<br>
<br>
Arbor says the average attack during 2013 Q1 was about 1.77 Gbps, up from about 1.48 Gbps in 2012 and this took into consideration the large Spamhaus DDoS attack<br>
<br>
What's your take on the massive difference between the averages ? does Prolexic see larger attacks because they protect larger networks ? or do they have less customers thus hence have a larger average ? one thing which isn't shown is how big the sample pool data is... or is someone cooking the books to put fear into network operators ?<br>
<br>
In a recent attack we saw sustained layer 7 attacks for over 24 hours , followed by a 1gbit attack lasting several hours and then short 10 minute attacks ranging from 2.5gbit to 17+gbit - graphs from the attacks can be found here if anyone is interested - <a href="http://www.micron21.com/ddos" target="_blank">http://www.micron21.com/ddos</a><br>

<br>
My point in bringing up S/RTBH was to note that one isn't limited to 'destroying the village in order to save it' via D/RTBH, and that there are in fact creative ways that operators can more safely provide their downstream customers with S/RTBH capability, such as a dual-advertisement strategy which a) triggers diversion of traffic destined to the attack targets into a mitigation center and b) denotes the attack source(s) to be dropped on the mitigation center coreward interfaces, thus only dropping traffic emanating from said attack sources and destined for attack targets whose traffic is being diverted through the mitigation center gateways.<br>

<br>
Yes, absolutely; it should be included in all router and layer-3 switch RFPs as a hard requirement.<br>
