摘要： Provided is a method by which a cable modem reports a downstream packet resequencing status to a cable modem termination system, and more particularly, a method of effectively reporting detailed information on a packet resequencing status by further defining a packet resequencing-related event and event-related information in a message reporting the packet resequencing status. The method by which a cable modem reports a resequencing status of the resequenced packets includes the steps of: when a packet resequencing-related event occurs, generating a resequencing status message (CM-STATUS) including packet sequence numbers of packets causing the event; 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 transmitting the resequencing status message to the cable modem termination system over the upstream band allocated by the band allocation request message. More detailed resequencing status information, such as the remaining capacity of the receive buffer and the resequenced packet map, for more packet resequencing-related events compared to the conventional downstream packet resequencing status reporting method, is transmitted to the CMTS, such that the CMTS copes more flexibly with situations that may occur upon packet resequencing.
