Re: IPv8 / BGP8 / CF

Jamie,

You should have spoken with the hyperscalers driving industry growth.
Apple, Google, Mirosoft, Amazon. Most modern silicon and routers are built
around them.

1. Modern routers are built on merchant silicon ASICs (Broadcom
Jericho/Tomahawk, Cisco Silicon One, Marvell Prestera, etc.)
2. Majority of these chips implement forwarding using fixed pipeline stages.
3. Lookup are done in TCAM (SRAM) structures pre-optimized for specific key
widths.
4. v4 lookup = ~32-bit key, v6 lookup ~128-bit key. Hard=ware pipelines are
dimensioned for these two widths.
5. IPv8 implies exceed entry width or require multi-stage lookups, reducing
scale, imo.

You have to realize that forwarding is not implemented in software. This is
not an incremental evolution like IPv4 to IPv6.
