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?
so are we saying here that the superhub uses additional buffering becuase it bonds more channels? I also thought the added buffering compared to the VMNG was on the upstream, which goes back to not making sense as the VMNG has the same amount of upstreams

Iggie would know but it seems the mods here have peed him off, maybe time to make use of the better moderation over at the alternative cable forum?
