摘要 |
A communication system that includes a supervisory node (e.g., a headend) and one or more remote nodes (e.g., cable modems). Packets are transmitted between the supervisory node and the one or more remote nodes via RF channels. A plurality of the RF channels are bonded, such that packets may be transmitted via any one or more of the RF channels that are bonded. Bonding may include higher-layer bonding and/or lower-layer bonding. In higher-layer bonding, the communication system further includes a forwarder and a plurality of edge modulators. Each edge modulator is connected to a different RF channel or group of RF channels. The forwarder determines to which edge modulator one or more packets or flows are to be transmitted. In lower-layer bonding, a packet is split into pieces. The pieces are assigned to respective RF channels that are associated with an edge modulator for transmission to a remote node. |
