The Border Gateway Protocol, or BGP, has been holding the Internet together, for more than two decades and nothing seems to be falling off the edge so far. As far as we can tell everyone can still see everyone else, assuming that they want to be seen, and the distributed…
The theme of a workshop, held at the start of December 2014 in Hong Kong, was looking at means to enable further scaling of the root server system, and the 1½ day workshop was scoped in the form of consideration of alternative approaches to that of the default activity of…
The Internet’s Border Gateway Protocol (BGP) is one of the most critical components of today’s Internet.

At the NANOG meeting in Baltimore this week I listened to a presentation by Patrick Gilmore on “The Open Internet Debate: Section 706 vs Title II†It’s true that this is a title that would normally induce a comatose reaction from any audience, but don’t let the title put you…
