Very fascinating read. Thank you for posting.

Could you please elaborate on this?
How do you engineer around having basically no buffers at all, and

The only viable merchant silicon chip that would be useful for a IXP is from
the StrataDNX-family which house the jericho/qumran/petra/arad chips from
broadcom. No packetbuffer in the exhangepoint will shred performance
significantly, especially when one of your bursty 100G customers starts send
Why don't we just swap out your 40g switch for a 100g switch? You've had the
40g one for a while, and we anticipate upgrades every 18-24 months.

You could try Mellanox. Some of the promotional stuff I've seen/heard
indicates their focus on appropriate sized buffers & low packet loss on
rate conversion.

I first sent to an IX-specific mailing list, but as I have yet to see the
message hit the list, I figured I would post it here as well.
We've had multiple requests for 100G interfaces (instead of Nx10G) and no one
seems to care about the 40G interfaces we have available.
