  • Publication number: 20120106365
    Abstract: A solution for network packet latency measurement includes, at a network device having a memory, storing a first time value indicating when an ingress port of the network device received a packet. The solution also includes storing a second time value indicating when an egress port of the network device received the packet for transmission towards another network device. The solution also includes storing a difference between the first time value and the second time value.

  • Publication number: 20120110411
    Abstract: A memory system including a content addressable memory (CAM) array and a non-CAM array. The non-CAM array, which may share word lines with the CAM array, stores one or more error detection bits associated with each row of the CAM array. A state machine reads entries of the CAM array and corresponding error detection bits of the non-CAM array during idle cycles of the CAM array. Error detection logic identifies errors in the entries read from CAM array (using the retrieved error detection bits). If these errors are correctable, the error detection logic corrects the entry, and writes the corrected entry back to the CAM array (an updated set of error detection bits are also written to the non-CAM array). If these errors are not correctable, an interrupt is generated, which causes correct data to be retrieved from a shadow copy of the CAM array.

  • Publication number: 20110299536
    Abstract: One embodiment of the present invention provides a switch. The switch includes a forwarding mechanism and a control mechanism. During operation, the forwarding mechanism forwards frames based on their Ethernet headers. The control mechanism operates the switch in conjunction with a separate physical switch as a single logical switch and assigns a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.

  • Publication number: 20110299533
    Abstract: Systems and techniques for processing and forwarding packets are described. Some embodiments provide a system (e.g., a switch) which determines an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and forward the packet based on the internal virtual network identifier and/or internal policy identifier. In some embodiments, the system encapsulates the packet in a TRILL (Transparent Interconnection of Lots of Links) packet by adding a TRILL header to the packet. In some embodiments, the scope of an internal virtual network identifier and/or an internal policy identifier may not extend beyond a switch or a module within a switch.

  • Publication number: 20110299414
    Abstract: Systems and techniques for processing and/or forwarding packets are described. An ingress switch can use a QoS mapping mechanism to map a first set of Quality of Service (QoS) bits in a packet received from a customer to a second set of QoS bits for use in a Transparent Interconnection of Lots of Links (TRILL) packet which encapsulates the packet. The first set of QoS bits can be different from the second set of QoS bits. The TRILL packet can be processed and/or forwarded in the network based on the second set of QoS bits. At the egress switch, the TRILL packet can be decapsulated and the original packet with the original QoS bits (or QoS bits that are different from the original QoS bits) can be forwarded to the customer's network. In this manner, some embodiments of the present invention can preserve the QoS bits across a TRILL network.

  • Patent number: 8004676
    Abstract: A method is provided for detection of analytes using the Surface Plasmon Resonance effect. The method comprises providing a metal film on a transparent substrate. The free surface of the metal film is exposed to a test sample. An anlyte in the sample can interact directly with the metal film or via analyte binding molecules (ABMs) complexed to the film. Light is directed incident to the surface of film in contact with the substrate. Light is reflected from the surface of the film under SPR conditions. The reflected light is collected and the second and/or third harmonics of the resulting electrical signal, which are indicative of the phase and polarization state of the reflected light, are determined. The second and third harmonics are correlated to the presence and/or concentration of the analyte.

  • Patent number: 7688815
    Abstract: An interconnect switch stores data messages received from one or more source devices and prioritizes the data messages received from each source device based on the order that the data messages were received from the source device. For each available destination device associated with the interconnect switch, the interconnect switch identifies the data messages with the highest priority that are to be routed to the available destination device and selects one of the identified data messages for the available destination device. The interconnect switch then routes the selected data messages to the available destination devices.

  • Patent number: 7623246
    Abstract: Disclosed is an optical sensing device, which comprises a light source emitting a light; a beam splitter; an SPR sensor unit comprising a sensing surface; and a detecting mechanism; and a converting unit converting the first beam and the second beam from the optical device into a two-dimensional interference fringe pattern. From the above-mentioned configuration, an extra phase shift of a detection beam in SPR phase measurement is obtained. The differential measurement approach has shown to achieve a sensitivity figure significantly better than the best result that can be obtained from the prior art in the field of the measurement based on an SPR sensor.
