Abstract
A plurality of downstream channels enables communications between a CMTS and a plurality of legacy and non-legacy cable modems. A dispersion mechanism optimizes channel bonding, such that the downstream channels are interoperable with DOCSIS™-compliant, legacy cable modems. A program identifier field distinguishes between bonded and non-bonded flows. For bonded flows, a bonding group is defined to bond a set of downstream channels. The packets for each bonding group are classified into channel queues at or near a MPEG level or a packet level. To mitigate congestion and multiplexing inefficiencies, the dispersion mechanism collects real-time information to determine which channel receives the bonded packets. The dispersion mechanism includes a queue manager and a priority manager. The queue manager dynamically creates queues and allocates queue memory. The priority manager spools the appropriate bytes to an MPEG encapsulation engine for the appropriate outgoing modulator.
