摘要： Embodiments enable an Ethernet over Coaxial (EoC) Coaxial Media Converter (CMC) that implements only a subset of the functions (e.g., MAC and PHY) of a cable modem termination system (CMTS). The CMC sits between an optical line terminal (OLT) and a plurality of cable modems (CMs) that it serves. From the network management side at the OLT, the CMC appears and can be managed like an optical network unit (ONU). From the subscriber side, the CMC provides the same connectivity functions to the CMs as a CMTS and serves to terminate coaxial connections from the CMs.

摘要： Examples included in this disclosure provide, among other things, the receipt of data intended for a destination at a switch of a switch module. In response to the receipt of data, the switch module may determine whether a local port on the switch is a member of a link aggregation group that includes the egress port on second switch. In response to such a determination, the switch module may update the forwarding table of the switch to indicate the local port is an egress port for the destination.

摘要： A physical layer device provides for synchronization of clocks in a communication network. A place holder for an alignment marker is inserted into a frame to be transmitted. Once the placeholder alignment marker is inserted into the frame, no additional data is added to the frame. Transmission of the frame including the placeholder alignment marker may also be delayed to allow data processing in subsequent blocks within a transmit block to complete prior to further processing of the frame including the placeholder alignment marker (e.g., timestamping, MACSec, etc.) to improve timing accuracy with a multi lane distribution environment.

摘要： A method of sending data to a switch fabric includes assigning a destination port of an output module to a data packet based on at least one field in a first header of the data packet. A module associated with a first stage of the switch fabric is selected based on at least one field in the first header. A second header is appended to the data packet. The second header includes an identifier associated with the destination port of the output module. The data packet is sent to the module associated with the first stage. The module associated with the first stage is configured to send the data packet to a module associated with a second stage of the switch fabric based on the second header.

摘要： In one embodiment, a connection is maintained between a pair of ethernet ports that have circuitry connected in series with the ports and receiving power-over-ethernet (PoE) from one of the ports, by providing a controllable bypass circuit coupled to the pair of ethernet ports in parallel with the circuitry receiving power-over-ethernet, sensing a preselected condition, and opening and closing the bypass circuit in response to the presence or absence of the preselected condition. Power sourcing equipment (PSE) may supply the one of the ports with power over ethernet, and the circuitry may transports data between the pair of ethernet ports. The circuitry may also supply the switch with a control signal in response to the detection of the preselected condition.

摘要： An interface switch which presents itself as switch to an enterprise fabric formed of the devices from the same manufacturer as the interface switch and that of a host or node to an enterprise fabric from a different manufacturer. This allows each enterprise fabric to remain in a higher performance operating mode. The multiplexing of multiple streams of traffic between the N_ports on the first enterprise fabric and the second enterprise fabric is accomplished by N_port Virtualization. The interface switch can be connected to multiple enterprise fabrics. All control traffic address mappings between virtual and physical addresses may be mediated and translated by the CPU of the interface switch and address mappings for data traffic performed at wire speed. Since the interface switch may preferably be a single conduit between the enterprise fabrics, it is also a good point to enforce perimeter defenses against attacks.
摘要翻译：一种接口交换机，它将自身转换为由与接口交换机相同制造商的设备形成的企业结构，以及主机或节点到不同制造商的企业架构的交换机。这允许每个企业架构保持在更高性能的操作模式。通过N_port虚拟化来实现第一企业架构上的N_ports与第二个企业架构之间的多个流量流的复用。接口交换机可以连接到多个企业面料。虚拟和物理地址之间的所有控制流量地址映射可以由接口交换机的CPU和用于以线速执行的数据流量的地址映射进行中介和转换。由于接口交换机可能优选地是企业面料之间的单个管道，所以强制执行外部防御以防止攻击也是一个好点。

摘要： A method is implemented by a network element to provide scalable hierarchical traffic management (HTM) over a plurality of network layers for a network and eliminate priority leaking caused by quick loopback batch scheduling that analyzes a subset of network layers to shorten processing time and resource requirements when the scalable HTM selects data packets to be forwarded. The method and system function as a low pass filter over the selected data packets to prevent low priority data packets being forwarded where higher priority data packets are available to be forwarded.
