A complicated picture. I posted on Nanog a few days back that there were some interesting recent trends visible: a) a drop in the growth of AS numbers being announced b) a drop in the growth of /24 prefixes and c) a hiatus in the growth of the number of entries in the BGP FIB tables in a number of ASs Most of these have visibly kicked in round late April one way or another My take on this is that there are two factors at play at present: a) a 'clean up' of the routing noise in the /23 - /32 prefix area b) a side effect of a more general economic slowdown regards, Geoff From scott at scottmarcus.com Wed Jul 25 21:12:44 2001 From: scott at scottmarcus.com (Scott Marcus) Date: 25 Jul 2001 18:12:44 -0700 Subject: BGP Route Table Entries Message-ID: <20010726011244.27358.cpmta@c000.snv.cp.net> An embedded and charset-unspecified text was scrubbed...
