Abstract:
1. A method by which a cable modem receiving resequenced packets over a plurality of channels reports a resequencing status of the resequenced packets, the method comprising the steps of: (a) when a packet resequencing-related event occurs, generating a resequencing status message (CM-STATUS) in which packet sequence numbers (PSN) of the resequenced packets causing the event are recorded on a field designated for the event, the resequencing status message including a sequence-out-of-range PSN list TLV, a rapid loss detection event PSN list TLV, and a timeout PSN list TLV, wherein the resequencing status message comprises a map of the resequenced packets stored in the cable modem, the map of the stored resequenced packets comprises at least one of a remaining window of a receive buffer of the cable modem, a next expected packet sequence number, an earliest packet sequence number of the stored resequenced packets, and a stored packet bitmap; (b) transmitting a band allocation request message for requesting a cable modem termination system to allocate an upstream band for transmission of the resequencing status message; and (c) transmitting the resequencing status message to the cable modem termination system over the upstream band allocated by the band allocation request message.
