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 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…
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…
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…
At APNIC Labs we’ve been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP.
I’ve often heard that security is hard. And good security is very hard. Despite the best of intentions, and the investment of considerable care and attention in the design of a secure system, sometimes it takes the critical gaze of experience to sharpen the focus and understand what’s working and…
Last month, in January 2014, I reported on the size of the Internet’s inter-domain routing table, and looked at some projection models for the size of the default-free zone in the coming years. At present these projections are looking at relatively modest levels of growth of some 7 – 8%…
The Border Gateway Protocol, or BGP, has been toiling away, literally holding the Internet together, for more than two decades and nothing seems to be falling off the edge of the Internet so far. As far as we can tell everyone can still see everyone else, assuming that they want…
If the motivation behind the effort behind securing BGP was to allow any BGP speaker to distinguish between routing updates that contained “genuine†routing information and routing updates that contained contrived or false information, then these two reports point out that we’ve fallen short of that target. What’s gone wrong?…
The Internet has managed to collect its fair share of mythology, and one of the more persistent myths is that from its genesis in a cold war US think tank in the 1960’s the Internet was designed with remarkable ability to “route around damage.” Whether the story of this cold…
