More Leaky Routes

Most of the time, mostly everywhere, most of the Internet appears to work just fine. Indeed, it seems to work just fine enough to the point that that when it goes wrong in a significant way then it seems to be fodder for headlines in the industry press.


NANOG 63: BGP Route Hijacks

This presentation looked at a number of specific examples of route hijacking. The examples included: Network hijacking to support the creation of bitcoin farms and bitcoin mining via hijacked pool of servers, which, in turn, may use a hijacked pool of routes. The scope of a Canadian hijack was limited…


NZNOG 2015: Networking the Pacific is not as simple as it seems

Jon Brewer for NSRC presented at NZNOG on the pacific networking scene. He did a really good job of showing how the pacific floor is covered by a mesh of fibre connecting the developed economies, but they have bypassed many of the smaller island economies. There are sound economic reasons…


NZNOG 2015: Virtual routers have a niche, but it IS a niche

Tim Nagy from Juniper presented on the virtual router model. This is when you take commodity hardware (PCs) and run a virtualized router image on it, to provide you with the same kind of functionality a real dedicated hardware router would do, but hopefully in a more scaleable manner for…


NZNOG 2015: Lets all run OpenWRT

Jed Laundry gave a brief impassioned call-to-arms. We need to stop expecting vendors to encode different systems and sell us different CPE when the actual need is for commonality, not difference. The way out is to push OpenWRT as a common standard with add-ons, and give the community a chance…


BGP in 2014

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…


Best Practices in Operating a Secure Routing Environment

The Internet’s Border Gateway Protocol (BGP) is one of the most critical components of today’s Internet. It’s the engine that ensures that when your application passes a packet into the network, the network is able to pass it onward to its intended destination. This routing protocol is the glue that…


What’s so special about 512?

The 12th August 2014 was widely reported as a day when the Internet collapsed. Despite the sensational media reports the following day, the condition was not fatal, and perhaps it could be more reasonably reported that some parts of the Internet were having a bad hair day. Media Reports about…


Whats so special about 512K?

In around 1990 Internet Engineering Task Force (IETF) was alerted to a looming problem: long before the Internet was a commercial reality it looked like we would hit two really solid walls if we wanted to make the Internet scale to a global communications system. The first problem was that…
