<p class="MsoNormal">Dear Sanjeev, all –<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think there is a huge difference between having an opinion on an application which is carried on the exchange, and taking action, -vs- an attack on the internet which is caused by deliberate malicious action, or incompetence of configuration.
For exchange points (and for any SHARED medium) to be useful, they must function with a set of community norms and one of those norms must be to exclude actors who allow attacks on the network to propagate.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A few other thoughts on this from an IXP operator point of view: Well run IXPs should also play their part in mitigating accidental attacks and educating those who caused them – the MANRS initiative for IXPs is a good place to start:
<a href="https://www.manrs.org/participants/ixp/">https://www.manrs.org/participants/ixp/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The recent BitCanal attacks show that ISP networks must filter their peers as well as their customers. A good way to do that whilst readying your own systems is to ensure that you peer with networks that you can not specifically trust
or filter via IXP MLP route-servers which apply strict filtering. A list of IXPs which do that is on the MANRS site (as it’s a mandatory requirement for a MANRS compliant MLP). This is such an important feature for the modern internet that when we built
the Asteroid automated IXP software, we did not create a mechanism for creating an MLP peering session without a prefix list to act as a filter.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Happy peering,<o:p></o:p></p>
