Then there's the interleaving to further assist the FEC functions which adds to the buffer requirements.

So you can't avoid higher latency in DOCSIS and my sense tells me that it would increase further with 8 bonded downstream channels.

Or have I misunderstood something?
except the excess buffering is on the upstream and that currently has no bonding?
