Hi,
Apologies for the delay in posting these notes. Gorry and I held a side meeting
in Prague on the topic of (lack of) use of jumbo frames, and what topics might
lie within the IETF’s remit to help promote greater use.
After talking to an AD it was suggested we raise the topic on the int-are
Apologies for not being able to make the meeting. Had I been able to
attend, the question I was going to ask was: with respect to overhead,
there's a constant factor 6x improvement when moving from 1500->9000
octets. How quickly do hardware performance improvements typically reach 6x
packet-per-sec

Right, I should have said *at best* a 6x improvement. The point I'm trying
to get to is: how much sense does it make to try to make the public
internet safe for jumbo frames? I honestly don't know, and since I wasn't
at the meeting, I don't know much much this was even a focus.
Thanks,
Kyle

We've got to teach the system how to negotiate and/or discover this. 9000 was
about right for fast Ethernet but it's small at gigabit Ethernet and above.
Petabit is probably coming within our lifetimes.
9000 would be a great starting point and 64k after that but like the ibmpc 640k
memory t
If we are going much beyond 9K, the hardware has to change, because a 32 bit
CRC doesn’t cut it for really large packets.
If the hardware has to change, we can push MTU negotiation into the hardware.
And completely bypass the momentum involved with getting every existing
implementation on the
