Also, I say 9000, but why is 9000 even the right number?
While that may have been a rhetorical question...
Because that is the value Alteon picked in the late 1990s when they
created the de facto standard for "Jumbo Frames" by including it in
their Gigabit Ethernet kit as a way to enable the systems of the day to
have a hope of getting link-rate :)
Perhaps they picked 9000 because it was twice the 4500 of FDDI, which
itself was selected to allow space for 4096 bytes of data and then a
good bit of headers.
