4.2.2.4.11 Interleave
This function is used in digital data transmission technology to protect the transmission against noise issue and data error.
If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded. Short bursts
of noise on the line can cause these data packets to become corrupt and the bridge has to re-request data which in turn
can slow down the overall rate at which data is transmitted.
Interleaving is a method of taking data packets, chopping them up into smaller bits and then rearranging them so that
once contiguous data is now spaced further apart into a non continuous stream. Data packets are re-assembled by your
bridge.
The diagram below is an example of how interleaved traffic is transmitted. (Figure 4.88)
