Optimising MTU setting in PPPoE ADSL Connections
Authored by: Gort on Sep 10, '05 01:31:32PM

I'm not sure I follow the math here. Each 1492 packet will be 32 48-byte chunks, for a total 1536 bytes, of which 34 are overhead, 10 padding. Each 1454 packet will be 31 chunks, for a total of 1488 bytes, of which 34 are overhead. So every 47616 bytes sent will be 31 of the 1492 packets or 32 of the 1454 packets, and

31 * 1492 = 46252
32 * 1454 = 46528

which is a smaller difference than the 875:856 suggested in the article.

(I'm not qualified to comment on the substance; but when I tried to work through the arithmetic, I ended up off your numbers).
