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...
