Hi Abe, the problem is that the AMS-IX data only covers the public fabric, but the peering connections between the big CDNs/clouds and the large ISPs all happen on private dedicated circuits as it is so much traffic that it does not make sense to run it over a public IX fabric (in addition to

NCS5K?

According to some slides from a russian cisco connect event, the upcoming small-size NCS 5501 and NCS 5502 will support 1M+ FIB and 50ms per port buffers. Seem to be killer boxes. 48x100GE in 2RU with large FIB & buffers? Loving it already. I wonder what prices will look like for those. With Go

Re: Advertising rented IPv4 prefix from a different ASN.

Re: Brocade SLX Internet Edge

Nicolas Fevrier has a very detailed blog post on how Cisco handles the prefixes on their Broadcom Jericho based NCS 5500 gear. https://xrdocs.io/cloud-scale-networking/tutorials/2017-08-03-understanding-ncs5500-resources-s01e02/ I'm pretty sure the principle is more or less the same for the Jeric
