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.
摘要翻译：提供了一种电缆调制解调器向电缆调制解调器终端系统报告下行分组重新排序状态的方法，更具体地，涉及一种通过进一步定义分组重排相关事件和事件发生相关事件来有效地报告关于分组重新排序状态的详细信息的方法，报告报文重新排序状态的消息中的相关信息。电缆调制解调器报告重排序分组的重新排序状态的方法包括以下步骤：当发生分组重排相关事件时，生成包括导致该事件的分组的分组序列号的重新排序状态消息（CM-STATUS）发送用于请求电缆调制解调器终端系统的频带分配请求消息，以分配用于传送所述重新排序状态消息的上行频带; 以及通过由频带分配请求消息分配的上行频带将重新排序状态消息发送到电缆调制解调器终端系统。与传统的下游分组重排状态报告方法相比，更多的重排序状态信息，例如与传统下行分组重排序状态报告方法相比更多的分组重排相关事件的接收缓冲区和重排序分组映射的剩余容量，被传送到CMTS，使得CMTS处理更灵活地应对在分组重新排序时可能发生的情况。
