Abstract
A first packet processing node in a header suppression mode suppresses transmission of one or more packet headers. A second packet processing node receives the packets from the first packet processing node over a network medium and sends the received packets to an endpoint. The second packet processing node includes a memory that contains the packet headers suppressed by the first packet processing node and appends the stored headers to the suppressed packets before sending the packets to the endpoint. Cable modems (CMs) include one or more Service Identifiers (SIDs) for establishing communication channels (microflows) with a Cable Modem Termination System (CMTS) through a cable medium. In another aspect of the intention, a cable modem network protocol is used between the CMTS and the CM to dynamically establish and modify multiple microflows between the CMTS and CM on the same cable modem SID.
