摘要： A media independent interface for interconnecting an integrated repeater front-end with one or more integrated interface devices, each having several physical layer devices for operation in conformance with IEEE 802.3u. The media independent interface, in a repeater implementation, shares transmit and receive data channels, and provides for dedicated control signals, thereby multiplexing shared channels across all of the physical layer devices in the integrated interface device.

摘要： A management frame circuit has a set of inputs coupleable to a management bus for carrying management frames. Upon receiving the management frames from the management bus, the management frame circuit determines whether each of the management frames conforms to a frame template. The management frame circuit then asserts an indication that a management frame is bad, if the management frame is determined to not conform to the frame template. The bad fame indication is later deasserted in response to recognition of a predetermined set of bits on the management bus.
摘要翻译：管理帧电路具有可耦合到用于承载管理帧的管理总线的一组输入。在从管理总线接收到管理帧时，管理帧电路确定每个管理帧是否符合帧模板。如果管理帧被确定为不符合帧模板，则管理帧电路然后断言管理帧不良的指示。响应于对管理总线上的一组预定位的识别，不良声誉指示随后被取消断言。

摘要： Dynamic assignation of addresses to multiple PHY devices by a management station coupled to each of the PHY devices permits the management station to uniquely address each PHY device without a priori knowledge of the PHY addresses. The addresses are assigned by the station and thereby knows the addresses to use to access specific PHY devices.
摘要翻译：由耦合到每个PHY设备的管理站向多个PHY设备的地址的动态分配允许管理站唯一地寻址每个PHY设备，而无需对PHY地址的先验知识。地址由站分配，从而知道用于访问特定PHY设备的地址。

摘要： Methods and apparatus for managing exchanges in a network device of a storage area network are disclosed. In a first “host-side” exchange initiated by an initiator and between the initiator and the network device, one or more frames are received from an initiator and/or sent to the initiator. At least one of the frames pertains to access of a virtual storage location of a virtual storage unit representing one or more physical storage locations on one or more physical storage units of the storage area network. One or more “disk-side” exchanges between the network device and one or more targets (i.e., physical storage units) are initiated in response to the first exchange. In the disk-side exchanges, one or more frames are sent from the network device to one of the targets and/or received from the target. Exchange information for the host-side exchange and the associated disk-side exchanges are updated throughout the exchanges.

摘要： An aggregation router architecture comprises a plurality of line cards coupled to at least one performance routing engine (PRE) via an interconnect system. The line cards include input cards having input ports coupled to subscribers and at least one trunk card configured to aggregate packets received from the subscriber inputs over at least one output port. The PRE performs packet forwarding and routing operations, along with quality of service functions for the packets received from each input line card over the interconnect system. The interconnect system comprises a plurality of high-speed unidirectional (i.e., point-to-point) links coupling the PRE to each line card. The point-to-point links couple the line cards to a novel logic circuit of the PRE that is configured to interface the line cards to a packet buffer and a forwarding engine of the PRE.
