Geoff Huston taking a withering look at the crapness of BGP in the Internet. As always, its quite crap excluding the fact that it actually works (more or less).
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 fabric of the Internet.
The long predicted apocalypse in the Internet routing table hasn’t come to pass so the those 15-year old Catayst 6500 switches will still be used in the Internet backbone for many years to come. Oh, yay.
None of the metrics indicate that we are seeing such an explosive level of growth in the routing system that it will fundamentally alter the viability of carrying a full BGP routing table anytime soon. In terms of the projections of table size in the IPv4 and IPv6 networks, the BGP sky is firmly well above us, and it’s not about to fall on our heads just yet!
