    • A plurality of downstream channels enables communications between a CMTS and a plurality of legacy and non-legacy cable modems. A dispersion mechanism optimizes channel bonding, such that the downstream channels are interoperable with DOCSIS™-compliant, legacy cable modems. A program identifier field distinguishes between bonded and non-bonded flows. For bonded flows, a bonding group is defined to bond a set of downstream channels. The packets for each bonding group are classified into channel queues at or near a MPEG level or a packet level. To mitigate congestion and multiplexing inefficiencies, the dispersion mechanism collects real-time information to determine which channel receives the bonded packets. The dispersion mechanism includes a queue manager and a priority manager. The queue manager dynamically creates queues and allocates queue memory. The priority manager spools the appropriate bytes to an MPEG encapsulation engine for the appropriate outgoing modulator.
    • 多个下行信道实现CMTS与多个传统和非传统电缆调制解调器之间的通信。 分散机制优化信道绑定,使得下行信道可与符合DOCSIS TM标准的传统电缆调制解调器互操作。 程序标识符字段区分粘合流和非粘结流。 对于键合流,定义键合基团以连接一组下游通道。 每个绑定组的分组在MPEG级或分组级处于或接近分类为信道队列。 为了减轻拥塞和多路低效率,分散机制收集实时信息以确定哪个信道接收绑定的分组。 分散机制包括队列管理器和优先级管理器。 队列管理器动态创建队列并分配队列内存。 优先级管理器将适当的字节卷绕到适合输出调制器的MPEG封装引擎。

    • A miniMAC implementation of a distributed CMTS in a hybrid fiber/coaxial (HFC) plant. The distributed CMTS comprises at least one network layer, at least one media access layer, and one or more physical layers. The at least one media access layer includes one or more miniMAC layers. The one or more miniMAC layers are remotely located from a remaining part of the at least one media access layer. The at least one network layer, the remaining part of the at least one media access layer, the one or more miniMAC layers, and the one or more physical layers each function as separate modules, enabling each layer to be in separate component locations of the HFC plant, yet having the at least one network layer connected to the remaining part of the at least one media access layer, the at least one media access layer connected to each of the one or more miniMAC layers, and each of the one or more physical layers connected to each of the one or more miniMAC layers. The one or more miniMAC layers are located in close proximity to the one or more physical layers in the HFC plant. The one or more miniMAC layers convert digital bit streams into packets and maintain timing constraints between the one or more miniMAC layers and the one or more physical layers.
    • 在混合光纤/同轴(HFC)设备中的分布式CMTS的miniMAC实现。 分布式CMTS包括至少一个网络层,至少一个媒体访问层以及一个或多个物理层。 所述至少一个媒体接入层包括一个或多个miniMAC层。 所述一个或多个miniMAC层远离所述至少一个媒体接入层的剩余部分。 所述至少一个网络层,所述至少一个媒体访问层的剩余部分,所述一个或多个miniMAC层以及所述一个或多个物理层各自用作单独的模块,使得每个层能够处于 HFC工厂,但是具有至少一个网络层连接到所述至少一个媒体接入层的剩余部分,所述至少一个媒体接入层连接到所述一个或多个miniMAC层中的每一个,并且所述一个或多个 物理层连接到一个或多个miniMAC层中的每一个。 一个或多个miniMAC层位于HFC工厂中的一个或多个物理层附近。 一个或多个miniMAC层将数字比特流转换成分组,并在一个或多个miniMAC层与一个或多个物理层之间维持时序约束。
