A data networking system designed to provide efficient, yet reliable,
transportation of data across a time division multiplexed network. This
invention allows for redundantly sending data segments wherein if bad
data segments are received, they can be resent in a dynamic manner
depending on the network condition and segments can be fragmented,
resized and sent with low overhead due to dynamic header sizes, segment
sizes, forward error correction, and cyclic redundancy checks. The result
is a very adaptive network that meets the demanding requirements of
networks such as power line and wireless while still being able to
transport data for voice, audio, video, computer, control, and the like.
