20140016503 | Track Light Powered Adapter for Wireless Networking Device - A wireless networking device adapter for provisioning a wireless network using new or existing track lighting. The adapter securely engages the track light channel and supports a commercially available wireless access point (WAP) device. A lock mechanism on the adapter prevents unexpected disengagement of the adapter from the track light channel, yet allows for operator removal. A power converter within the adapter powers the WAP device from the electrical power provided by the track light channel. Multiple adapters communicate to form a mesh network to improve wireless network fault tolerance, or may operate in a repeater mode configuration or some combination. | 01-16-2014 |

20110058573 | USER SELECTABLE MULTIPLE PROTOCOL NETWORK INTERFACE DEVICE - An Ethernet/Fibre Channel network interface device which can be configured by a user to operate on an FC SAN, a CEE network or both. In one embodiment the configuration can be done using jumpers or connections to the pins of a chip, thus allowing a manufacturer to only inventory one device for use with either or both networks. In a second embodiment the configuration can be done in software by setting registers and memory values on the device. This embodiment allows the device to be changed between configurations without removing it from the server or blade. The devices according to the preferred embodiments further reduce power consumption by shutting down portions of the chip not needed based on the configuration of the device. | 03-10-2011 |

20120023082 | Longest Prefix Match Using Binary Search Tree - Longest Prefix Match (LPM) is implemented using a binary tree based search algorithm. Masked entries are stored in a plurality of binary search engines, wherein each of the binary search engines stores masked entries of a corresponding mask length. A search value is applied to each of the binary search engines in parallel. The search value is masked within each of the binary search engines, thereby creating a plurality of masked search values, each having a masked length equal to the mask length of the corresponding binary search engine. Each of the masked search values is compared with the masked entries of the corresponding binary search engine. An LPM result is selected from the binary search engine that detects a match, and has the longest corresponding mask length. Alternately, each binary search engine stores masked entries of N mask lengths, and N consecutive comparisons are performed to identify the LPM. | 01-26-2012 |

20110267952 | DYNAMIC LATENCY-BASED REROUTING - A switch creates and dynamically updates a latency map of a network to adjust routing of flows. Further, the network is monitored to detect latency issues and trigger a dynamic adjustment of routing based on the latency map. In this manner, a flow can be routed along a route (i.e., a faster route) that provides less latency than other available routes. The latency map can be generated based on latency probe packets that are issued from and returned to the source switch. By evaluating many such latent probe packets that have traveled along many available routes (e.g., corresponding to various ports of the switch), the switch or associated administrative logic can dynamically adjust the latency map to updated latency information of available routes. Therefore, responsive to a trigger, the source switch can dynamically adjust the routing of a flow based on latency issues discerned from the network. | 11-03-2011 |

20120096310 | REDUNDANCY LOGIC - A network system provides network device having a secondary memory that mirrors the content of a primary memory maintaining data structure parameters entries. The integrity of each data structure parameter entry is tested as the entry is output from the primary memory, such as by using a parity test. If an error is detected in the entry, a corresponding entry from the second memory structure is select for use instead of the entry from the primary memory. The corresponding entries in each memory are then flushed, updated, synchronized, or overwritten from the each memory and processing continues using the new entries or other entries from the primary memory. In the rare instance that corresponding entries from both memories exhibit an error, then an error notification is issued. | 04-19-2012 |
20120099602 | END-TO-END VIRTUALIZATION - One embodiment of the present invention provides a system that facilitates end-to-end virtualization. During operation, a network interface residing on an end host sets up a tunnel. The network interface then encapsulates a packet destined to a virtual machine based on a tunneling protocol. By establishing a tunnel that allows a source host to address a remote virtual machine, embodiments of the present invention facilitate end-to-end virtualization. | 04-26-2012 |

20110231570 | Method and Apparatus for Mirroring Frames to a Remote Diagnostic System - Apparatuses and methods to mirror frames received at an input port or provided by an output port to a port not connected to the device performing the mirroring operation. A frame being sent to a diagnostic system has a mirror header added to allow the frame to be routed through any intervening switches in the same fabric. The final switch or the diagnostic system removes the mirror header. If the diagnostic system is attached in a different fabric, encapsulation and inter-fabric routing headers are added as needed to the frame containing the mirror header. This allows the frame to traverse multiple fabrics to reach the diagnostic system. The encapsulation and inter-fabric routing headers are removed as done normally. This allows a diagnostic system to be connected to any switch in the network, either in the same or a different fabric. | 09-22-2011 |

20140078112 | USING MULTIPLE SIGNALS TO DETECT TOUCH INPUT - Detecting a location of a touch input is disclosed. Each of a plurality of transmitters coupled to a propagating medium emits a signal that is distinguishable from other signals emitted from other transmitters.
