ABSTRACT:
Data packets transmitted over a cable network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the CM and the CMTS. An extended header element is added to a data packet that is to be transmitted over the cable network. The extended header element contains an index that is used along with the SID to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.
