The ethernet payload is 1500 bytes. Devices have to deal with a huge number of frames, where many are fragments of one and the same message. More than a thousand just for an image file for example.
Data transfer could rise more and more in the future, with millions or much more fragments for a message during its life-time on its way from A to B.
So, I wonder if extending the frame size is an option, with the idea of getting the same done as current ethernet but with less frames and less fragmentation overhead.
So far, I only thought of these potential problems:
- the CRC may fail often when the frame is too big
- big frames could be less flexible regarding flow control
