Stories of BGP routing mishaps span the entire thirty-year period that we’ve been using BGP to glue the Internet together. We’ve experienced all kinds of route leaks from a few routes to a few thousand or more. We’ve seen route hijacks that pass by essentially unnoticed, and we’ve seen others…
The first RFC describing BGP, RFC 1105, was published in June 1989, thirty years ago. By any metric that makes BGP a venerable protocol in the internet context and considering that it holds the Internet together it’s still a central piece of the Internet’s infrastructure. How has this critically important…
The first part of this report looked at the size of the routing table and looked at some projections of its growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing…
It has become either a tradition, or a habit, each January for me to report on the experience with the inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection…
The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If…
One way or another we’ve been working on various aspects of securing the Internet’s inter-domain routing system for many years. I recall presentations dating back to the late ’90’s that point vaguely to using some form of digital signature on BGP updates that would allow a BGP speaker to assure…

RIPE held its 75th meeting in Dubai in mid-October. As usual there was a diverse set of presentations covering a broad range of activities that are taking place on today’s Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centres, IPv6,…
It’s hard to classify the IEPG meetings that occur at the start of the IETF week. Many years ago they had a role in allowing network operators to talk to other operators about what they were seeing and what they were thinking about. Those days are long since over, and…
The Border Gateway Protocol (BGP) is the routing protocol that literally keeps the Internet glued together. The public Internet is composed of some 58,000 component networks (BGP calls them “Autonomous Systems” (AS’s)), many of which are very small, while some are very large both in terms of geographical coverage and…
