Abstract:
1. A method of intelligently collecting and using DOCSIS control information in a cable modem communication network by an intelligent node to improve upstream signal transmissions on the network, said intelligent node being in communication with a cable modem termination system (CMTS), cable modems (CMs), and other devices, the method comprising: the intelligent node obtaining CM identifier information for CMs and other devices on said network; the intelligent node obtaining control information from said cable modem communication network, including at least one of a DOCSIS MAP or a DOCSIS UCD control structure; the intelligent node synchronizing to a DOCSIS timestamp clock maintained by said cable modem communication network; the intelligent node using said obtained control information and said CM identifier information to determine when a device is scheduled to transmits on an upstream communication link; the intelligent node using the obtained control information to modify transmissions on the upstream communication link; and the intelligent node receiving upstream data traffic from a sub-node, demodulating the received upstream data traffic from the sub-node, compressing the demodulated received upstream data traffic from the sub-node, re-modulating the compressed demodulated received upstream data traffic data, and re-transmitting the compressed data to the CMTS so as to reduce the bandwidth requirements on the section of an HFC network upstream of the sub-node.
