Hello,
How is the end of an Ethernet II frame detected?
The frame has no length field in it, and I'm
wondering how its end is detected? Does the
ethernet adapter detect when voltage transitions
stop? Is there an idle state for the differential
transmitter which is then detected? Something simpler
than that even? The specification appears to include
an interframe gap of 96 bit times -- is part of
the reason for this gap to allow the ethernet adapter
to detect the end of the frame?
Thanks very much!
