at the University of Oregon, and sending this email to seek your help
for validating the research results for one of our network measurement
projects.</div><div style="font-family:HelveticaNeue"><br>We have
conducted a large scale measurement study to infer the private (both
physical and virtual) and public interconnections between Amazon/AWS
network and all other ASes across the Internet along with their metro
area where they are located. More information about this project can be
found at <a href="https://ix.cs.uoregon.edu/~byeganeh/cloudx/">https://ix.cs.uoregon.edu/~byeganeh/cloudx/</a>. We are interested in validating at least
part of our results against ground truth. If you are managing an AS that
has one or more direct peerings with any of Amazon's networks (AS7224,
AS16509, AS19047, AS14618, AS38895, AS39111, AS8987, and AS9059) and aware of their IPs and locations, it would be extremely
valuable if you could validate our inferred peering between your AS and
Amazon at the <i>aggregate level </i>(i.e. just indicating what fraction
of our inferred interconnections for your network is correct). We will
report this aggregate result in our study without revealing the identity
of your network.<br><br>If you have any questions or need more information about this project, please feel free to contact me.</div><div style="font-family:HelveticaNeue"><br></div><div style="font-family:HelveticaNeue">I appreciate your prompt response as we are trying to submit this study to a conference in a few weeks.</div><div style="font-family:HelveticaNeue"><br>Regards, </div><div style="font-family:HelveticaNeue">Bahador Yeganeh</div></div></div>
