International Classification:

H04L 12/56

US Classification:

370395400

Abstract:

A flow bonder at a CMTS and another at a cable modem distribute packets of a service flow over multiple channels and collect them in the downstream direction respectively; vice versa in the upstream direction. The collector uses a service flow identifier and a sequence number identifier inserted by the distributor into each packet of the flow to reassemble the packets into the order they left the distributor. Packets received at the collector are stored to a buffer. If a stored packet is the next to be transmitted, it is transmitted. If not, the collector waits a predetermined period until the next packet to be sent is received. If it is not received during the wait period, the previously stored packet is sent. The wait period is based on the maximum transmission time difference between any two of the multiple channels.
