DOCSIS 3.0 required that CM must have 4 or more upstream channel transmitters. This translates into the

possibility of 100mbps+ upstream rate…

Removed DOCSIS 2.0/1.x single request-grant cycle bottleneck.

Bonded Flows allow multiple outstanding BW-REQ.

BW can be requested on any of the bonded upstream channels

Requests can be granted on any of the bonded upstream channels

Reduced upstream latency (TCP ACK) also increases DS throughput. [TCP application]

Bonds multiple, physical upstream transmit channels to form a larger, logical upstream channel.
