Abstract: A method and a network device for sharing bandwidth among a group of classes of traffic for an interface are provided. Bandwidth may be allocated to at least one traffic class of a first priority for the interface. At least some unused bandwidth of the at least one traffic class may be allocated to at least one other traffic class of a second priority for the interface. In some implementations, weighted constituents may be allocated unused interface bandwidth based on an assigned weight of each of the weighted constituents of the interface.

Abstract: A buffer memory may be configured to temporarily store data in a number of queues. A processor may be configured to measure a fullness of the buffer memory. The processor may also be configured to assign sizes to the number of queues based on the fullness of the buffer memory. The processor may also adjust thresholds of drop profiles associated with the number of queues based on the sizes assigned to the number of queues.

Abstract: A unicast/multicast system has an internal cell generating section that generates an internal cell to include its output index information based on user data, and an output port conversion table that stores the relation of output index information and output port number for the internal cell in the form of one-to-one for the unicast and one-to-multiple for the multicast.

Abstract: A system provides search results from a voice search query. The system receives a voice search query from a user, derives one or more recognition hypotheses, each being associated with a weight, from the voice search query, and constructs a weighted boolean query using the recognition hypotheses. The system then provides the weighted boolean query to a search system and provides the results of the search system to a user.

Abstract: A semiconductor memory device may include an intergate dielectric layer of a high-K, high barrier height dielectric material interposed between a charge storage layer and a control gate. With this intergate high-K, high barrier height dielectric in place, the memory device may be efficiently erased using Fowler-Nordheim tunneling.

Abstract: A gateway for screening packets transferred over a network. The gateway includes a plurality of network interfaces, a memory and a memory controller. Each network interface receives and forwards messages from a network through the gateway. The memory temporarily stores packets received from a network. The memory controller couples each of the network interfaces and is configured to coordinate the transfer of received packets to and from the memory using a memory bus. The gateway includes a firewall engine coupled to the memory bus. The firewall engine is operable to retrieve packets from the memory and screen each packet prior to forwarding a given packet through the gateway and out an appropriate network interface. A local bus is coupled between the firewall engine and the memory providing a second path for retrieving packets from memory when the memory bus is busy.

Abstract: A system provides congestion control and includes multiple queues that temporarily store data and a drop engine. The system associates a value with each of the queues, where each of the values relates to an amount of memory associated with the queue. The drop engine compares the value associated with a particular one of the queues to one or more programmable thresholds and selectively performs explicit congestion notification or packet dropping on data in the particular queue based on a result of the comparison.

Abstract: A controller may include a measurement circuit configured to generate a proxy signal representing delay variations in the controller. The measurement circuit may also generate a measurement value from the proxy signal. A control circuit may be configured to convert the measurement value into a control value. A delay circuit may be adjusted by the control value to alter an amount of delay of a signal.

Abstract: A voltage regulator may include an operational-amplifier section, a capacitor connected to an output of the operational-amplifier section, and a switch configured to connect the capacitor to a voltage supply. The switch is configured to charge the capacitor before activating the operational-amplifier section. The capacitor is configured to store charge to supplement current being supplied from the operational-amplifier section. The voltage regulator may be used to supply power to non-volatile memory cells.

Abstract: A system automatically creates a list from items in existing lists. The system receives one or more example items corresponding to the list and assigns weights to the items in the existing lists based on the one or more example items. The system then forms the list based on the items and the weights assigned to the items.

Abstract: A system identifies a document and obtains one or more types of history data associated with the document. The system may generate a score for the document based, at least in part, on the one or more types of history data.

Abstract: A method for processing high priority packets and low priority packets in a network device includes performing arbitration on high priority packets until no high priority packets remain. Arbitration then is enabled on low priority packets. A packet size associated with the selected low priority packet is compared with a programmable threshold. Low priority packets are excluded from subsequent arbitration for a programmable duration when the packet size exceeds the programmable threshold.

Abstract: A system includes a group of devices and a shared memory that is partitioned into blocks that are capable of being allocated to the group of devices using linked lists. The system also includes check logic configured to store a group of bits, where each bit corresponds to one of the blocks, and counter logic configured to count for a predetermined period of time. The system further includes logic configured to clear the group of bits stored in the check logic, cause the counter logic to count for the predetermined period of time, monitor a de-allocation of the blocks in the shared memory, set, for each of the blocks that is de-allocated during the predetermined period of time, the corresponding bit in the check logic, identify, after the predetermined period of time, one or more bits that have not been set, and mark the blocks corresponding to the one or more bits as available for allocation.

Abstract: A switching device in a network system for transferring data includes one or more source line cards, one or more destination line cards and a switching fabric coupled to the source line cards and the destination line cards to enable data communication between any source line card and destination line card. Each source line card includes a request generator to generate a request signal to be transmitted in order to obtain an authorization to transmit data. Each destination line card includes a grant generator to generate and send back a grant signal to the source line card in response to the request signal received at the destination line card to authorize the source line card to transmit a data cell to the destination line card.

A verify status value is stored for each subgroup, the verify status value indicating a verify status of each subgroup, wherein the verify status value indicates whether an associated subgroup has been program verified. A program verify operation is performed on a selected subgroup when the verify status value associated with the selected subgroup indicates that the selected verify subgroup has not been program verified.

The method also includes setting a new path having a bandwidth that is at least two times the necessary bandwidth for transferring a VoIP packet, when it is determined that the first path does not exist.

All hardware and software devices, as well as people can be virtualized in the virtualized network. Once virtualized, persons and devices (real world entities) are able to communicate immediately and directly.
