IPv6 News

BGP has been toiling away, literally holding the Internet together, for close to two decades now, and nothing seems to be falling off the edge of the Internet. In October 2006 a workshop convened by the Internet Architecture Board can to the conclusion that: "routing scalability is the most important problem facing the Internet today and must be solved [...] The routing scalability problem includes the size of the DFZ RIB and FIB [and] the implications of the growth of the RIB and FIB on routing convergence times." The question I'd like to ask here is whether anything has changed in this perspective on BGP since late 2006? Are the prospects of the medium term collapse of BGP through scaling overload still a realistic option for the routing environment? Should we still be concerned about routing scaling? Is the BGP sky about to fall on our heads? Lets look at BGP across 2008 to see if any answers to these questions are lurking in the data.
