ME> Date: Sat, 4 Mar 2006 19:01:14 -0500 ME> From: Marshall Eubanks ME> So, if we gave every active ASN a contiguous IPv6 block, and moved ME> everyone over to IPv6, we would REDUCE the size of the routing table ME> by a factor of 8.28. That would gain several years of growth before ME> the routing table is the size it is now. Exactly. Fragmentation doesn't help... ME> Don't hand these out in contiguous blocks, though. One simple ME> procedure would just be to hand out the first /48 from, say, a /38 ME> and reserve the rest of the /38 for future growth of that ASN. ...and was/is caused by stride-n allocation policies where "n" is too small. (Would any sane software developer use strictly skip lists and unsorted arrays?) Exponential problems need logarithmic solutions. ME> I am sure that better procedures could be arrived at "Allocate from the middle of the largest contiguous block. Align as appropriate." Exponential problems need logarithmic solutions. ME> With luck, that would snowball into actual usage. It depends how forward-thinking people are. A carrot now to avoid a stick later would appear enticing...
