摘要： A method for dropping lower priority packets for transmission over a wireless communication medium is provided. A central device receives one or more packets to be transferred to one or more data providers, each packet having a priority. Then, based on the priority, a media access controller stores each of the packets in one or more priority queues in a fixed shared memory space in such a way as to maintain the order in which the packets were received in each of the priority queues. The media access controller monitors the number of packets in each of the priority queues and signals an interrupt when a packet threshold is exceeded in one or more of the priority queues. The media access controller then drops lower priority packets in the fixed shared memory space based on the order received to guarantee that there is enough memory to store higher priority packets in the fixed shared memory space.

摘要： A method and system for creating an ethernet-formatted packet from an upstream DOCSIS packet. The upstream packet is first received along with packet characteristic data that is contained in physical layer prepend data and in the packet header. A packet tag is then created, based on the packet characteristic data. The packet characteristic data includes identifiers for the transmitting remote device and the channel over which the transmission is sent. Packet characteristic data also includes information about the physical characteristics of the transmission signal, such as the power level and time offset. The packet characteristic data also includes administrative information, such as the minislot count at which the packet is received and whether the packet was received in contention. The packet tag is appended to the payload of the upstream packet. Also appended to the payload is an encapsulation tag, and source and destination address headers. The result is a packet in an ethernet format. The resulting packet can therefore be sent using the ethernet protocol. The packet includes information that characterizes a DOCSIS packet. In a distributed cable modem termination system, this additional characterizing information can be used by processes further upstream, such as packet classification. An analogous operation can take place with respect to packets going downstream. Here, a DOCSIS packet is formed at an intermediate node, on the basis of a received ethernet-formatted packet.
摘要翻译：一种用于从上游DOCSIS数据包创建以太网格式的数据包的方法和系统。首先将上行分组与包含在物理层前置数据和分组报头中的分组特征数据一起接收。然后基于分组特征数据创建分组标签。分组特征数据包括用于发送远程设备和发送传输的信道的标识符。分组特征数据还包括关于传输信号的物理特性的信息，例如功率电平和时间偏移。分组特征数据还包括管理信息，诸如接收分组的小时隙计数，以及是否在竞争中接收分组。分组标签被附加到上行分组的有效载荷。还附加到有效载荷上的是封装标签，以及源和目标地址头。结果是以太网格式的数据包。因此，可以使用以太网协议发送生成的数据包。该分组包括表征DOCSIS分组的信息。在分布式电缆调制解调器终端系统中，该附加特征信息可以被进一步上游的进程使用，诸如分组分类。对于下游的数据包，可以进行类似的操作。这里，DOCSIS分组基于接收的以太网格式的分组形成在中间节点处。
