Any given interface is inherently rate limited.
When demand exceeds the capacity, something must be
done. Often this is done w/ "striping" or "muxing"
where multiple "low-speed" channels are "bonded" into
a single virtual path. L1 is not that different than
L2 & L3 in these cases. The specific dynamics are
unique per layer but the problem remains the same.
