摘要： A method, system and computer program product in a downstream line card of a Cable Modem Termination System (CMTS) for managing downstream traffic for channels and bonded channel groups is provided herein. The method comprises the step of receiving packets for transmission to cable modems and classifying each packet to a flow based on class of service associated with the packet. The method further includes the step of storing the packets in flow queues based, wherein a flow queue is selected based on a flow a packet is associated with and wherein each flow corresponds to a single flow queue. The method also includes transmitting the packets from the flow queues to channel queues or bonded channel queues using corresponding channel nodes or bonded channel nodes at a rate that is determined based on feedback data and scheduling downstream transmission of packets on a single downstream channel if the packet is stored in a channel queue and on multiple downstream channels that are bonded together to form a bonded channel group if the packet is stored in a bonded channel queue. The feedback data is adjusted for each channel node or bonded channel node based on a queue depth for a corresponding channel queue or bonded channel queue.

摘要翻译： 本文提供了用于管理信道和绑定信道组的下行业务的有线调制解调器终端系统（CMTS）下游线路卡中的方法，系统和计算机程序产品。 该方法包括以下步骤：接收用于传输到电缆调制解调器的分组，并且基于与分组相关联的服务类别将每个分组分类为流。 该方法还包括基于流队列存储分组的步骤，其中基于分组与其相关联的流程选择流队列，并且其中每个流对应于单个流队列。 该方法还包括：使用对应的信道节点或绑定信道节点，将数据包从流队列发送到通道队列或绑定信道队列，速率是基于反馈数据确定的，并且调度单个下行信道上的分组的下行传输，如果分组 如果分组被存储在绑定信道队列中，则被存储在通道队列中以及多个下行信道上，所述多个下行信道被绑定在一起以形成绑定信道组。 基于对应的信道队列或绑定信道队列的队列深度，为每个信道节点或绑定信道节点调整反馈数据。
