摘要： Redundancy of data and/or inline power in a wired data telecommunications network from a pair of network devices via a selection device is provided by communicating redundant signals with each of the pair of network devices and coupling ports of the first network device and corresponding ports of the second network device to paired inputs of the selection device. The selection device operates: 1) under the control of the pair of network devices, one acting as master and one as slave, the master selecting (for each port or for all ports) one of the two paired inputs and causing the selection device to communicate data and/or inline power via a third port of the selection device to a third network device receiving data connectivity and/or inline power from the selection device; or 2) to route two redundant signals to a third network device which then selects one for use.

摘要： The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.

摘要： A shortcut technique implements forwarding decision shortcuts at a switch for frames routed between subnetworks of a computer network. The switch monitors the flow of a first frame of a particular type to and from the router, which renders a forwarding decision for routing the frame. The switch records information stored in network layer header of a packet encapsulated within the first frame, and then compares that information with the information stored in network layer headers of packets contained within subsequent frames of that particular type. Forwarding decisions for these subsequent frames are then rendered by hardware logic circuits of the switch rather than by the router.

摘要： A network node determines the suitability of coupled devices for being remotely line powered before actually powering them. The node scan its ports to determine which ports are coupled to devices. The node then interrogates the coupled devices. A unique discovery tone or bit pattern is generated and sent to devices coupled to ports. The node then monitors the port for a return signal. If there is a return signal, it is compared to the transmitted discovery signal. The signal will be identical after allowing for line losses if the coupled device is suitable for remote line powering. If the comparison yields a match, the network node supplies remote line power to the device.

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a first network device and a second network device configured as power sourcing equipment (PSE) devices and coupled together and to a third network device (such as a PD) via a Y device is provided by providing redundant signaling to/from each of the pair of network devices, and coupling a port of each of the network devices to the Y device and from there to a third port where a third network device such as a PD may be coupled. Because the Y device is essentially passive, communications paths between the PSE devices and the PD are provided for negotiating master/slave status and other status and related information among the respective network devices. Dynamic impedance matching is provided to handle situations where not all devices are plugged in and as a communications technique among the devices.

摘要： Redundancy of data and/or Inline Power in a wired data telecommunications network from a pair of power sourcing equipment (PSE) devices via an automatic selection device is provided by providing redundant signaling to/from each of the pair of PSE devices, and coupling a port of one PSE device and a redundant port of the second PSE device to respective first and second interfaces of a port of the selection device. The selection device initially selects one of the two PSE devices and communicates data and/or Inline Power to a third interface of the selection device. A powered device (PD) coupled to that third interface communicates data and/or Inline Power with the selected one of the first and second PSE device through the selection device. Upon detection of a condition, such as a failure condition, the selection device may select the other of the two interfaces.
