Abstract: Nodes of a multichannel mesh network generate channel-metric matrices for routing packets to destinations based on a bottleneck channel identified for the source-destination pair. The identification of bottleneck channels increases the diversity among the different communication channels used along a route. This link-state routing approach may allow better paths to be found.

Abstract: A method of sending a packet from a source node to a destination node in the same broadcast domain. The packet is associated with a traffic flow directed from the source node to the destination node. The source node is connected with the destination node via a first and a second communication path. A criterion based on an attribute of the traffic flow is measured for each of the communication paths. One path is selected between the first and second communication paths based on the measured criterion and the selected communication path is assigned to the associated traffic flow. The packet is then sent via the selected communication path.

Abstract: Embodiments of methods and apparatus for providing a dynamic on-demand routing protocol are generally described herein. In some embodiments, a method is disclosed comprising receiving, by a destination node, a first route request from a source node over a plurality of routes between the source node and the destination node, and selecting, by the destination node, a first route and a second route from the plurality of routes as a current route and a candidate route, respectively. Other embodiments may be described and claimed.

Abstract: A search engine system (100) compares search key values to stored entry values, and includes first blocks of entries (102) and second blocks of entries (104). First blocks of entries (102) can be “search” blocks that can provide a relatively fast search speed of stored data value, and each store a unique first portion of one or more entry values. Second blocks of entries (104) can be randomly accessible entries logically arranged into search nodes that each correspond to a first portion of an entry value stored in the first block of entries. Each search node can include one or more second portions of an entry value.

Abstract: A wireless mesh network router comprises at least one transceiver to receive a packet over a wireless communication channel and path selection circuitry. The packet identifies a source node and a destination node in a multichannel mesh network. The path selection circuitry combines a channel-metric matrix associated with the packet's source node and a channel-metric matrix associated with the packet's destination node to determine a bottleneck channel for the source-destination pair. The next-hop node and associated transmission channel may be selected from the destination node matrix based on the bottleneck channel.

Abstract: An improved architecture for a network search engine (NSE) is disclosed herein as including an interface manager, one or more levels of a splitting engine, an array of data processing units (DPUs), and a cascade block. A method for using the improved NSE architecture to form an efficient pointer entry database is also provided. As described herein, the improved NSE architecture simultaneously provides high speed, search throughput, update rate and capacity, coupled with low power and fixed latency searches for all search key widths.

Abstract: An apparatus comprises a forwarding component configured to forward data by looking up a routing table, another forwarding component configured to receive the data, and an intermediate forwarding component bridging the two components to forward the data without looking up the routing table.

Abstract: An apparatus for effectively powering non-motor loads with solar power includes a solar array for producing DC power; a variable frequency drive (VFD) connected to the VFD for converting the solar DC power to AC power; a power transformer connected to the VFD; and a non-motor load connected to the power transformer. The power transformer is selected to provide a desired operating voltage to the non-motor load, typically 120 V. The power transformer may have a primary with a delta configuration and a secondary with a wye configuration. The system can be used to operate incandescent and fluorescent lamps, and to power UPS systems.

Abstract: A solar powered system controls multiple motors directly from a single solar power source with a single variable frequency drive (VFD). A control system selectively connects and disconnects individual motors as solar power varies so that the available power can be used effectively and some of the motors can be kept operating rather than shutting down the entire system. The control system includes a detection circuit for detecting the solar array voltage, and a selection circuit for providing shutoff control signals to individual motors based on the solar array voltage and preselected motor shutoff priority criteria.

Abstract: A hybrid power system has two voltage sources, a variable DC power source, and a second power source, connected through selection components to a common node. The variable DC power source may be a solar power source and the second source may be an AC grid. The selection components, e.g. blocking diodes, SCRs, or relays, allow one or both of the sources to be connected to the node depending on the voltages produced by the sources. A variable speed drive and load may be connected to the node.

Abstract: A modularized routing system includes a control element and forwarding elements, all of which are connected via a private network, for example, an Ethernet. The control element computes a routing table for each of the forwarding elements. Based on information in the routing table, a forwarding element decrements a time-to-live counter in the packet header only if the forwarding element is the first one in the routing system encountered by the packet. Accordingly, the forwarding elements preserve the behavior of a single router while using substantially the same routing protocols as the single router.
