If there is IP fragmentation, is there also Ethernet fragmentation?
I tried to google it but there seems to be no such thing.
So what if, for example, we encapsulate Ethernet into ATM, what would the ATM payload look like?
The payload size of ATM is only 48 bytes, but the minimum frame size of Ethernet is 64 bytes. How can we fit an Ethernet frame into the payload of an ATM frame?
Or what if, for example, we encapsulate Ethernet into a T1 frame;
A T1 frame is only 193 bits, with 1 bit of header and 192 bits (24 bytes) of payload. How can an Ethernet frame fit inside the payload of a T1 frame?
