If you wish, you can also consider Alternate 3 for 9kB: 72us@1Gbps, 7.2us@10Gbps, .72us@100Gbps, .072us@1Tbps.

So?

Have you learned enough about Moore's law that, at 10Gbps era, 72us of delay is often significant?

I frankly haven't thought about it any further. You say 1280+ belongs in ITU, and I say 1280- belongs in ATM. Larger packets means fewer interrupts and fewer packets in flight, which is good Moore's law or no. Accommodation of MTU diversity is what matters. Fred fred.l.templin@boeing.com
