Abstract: A signal-linearization system and method reduces nonlinear distortions in a digitized signal generated by an analog-to-digital converter (ADC) when converting an analog input signal from analog to digital form. A signal adder adds a dither waveform to the analog input signal. An ADC includes sample-and-hold (S/H) circuitry and quantizer circuitry. The ADC converts the analog input signal with the added dither waveform into a digitized signal. The dither waveform operates to suppress nonlinear distortions attributed to the quantizer circuitry. A linearizer processor performs nonlinear equalization (NLEQ) on the digitized signal to suppress nonlinear distortions attributed to the S/H circuitry. A dither waveform removal module removes a digital counterpart of the dither waveform from the digitized signal.

Abstract: A sorter system includes a clock continuously generating a series of clock signals, a systolic array circuit, and control circuitry in communication with serial access memory that stores data items of a sequence to be sorted and with the systolic array circuit to supply thereto data items as input and to receive therefrom data items as output. The systolic array circuit includes at least one processing module and K-1 registers, where K is an integer value greater than two. Each processing module has at least one of the registers, each register for storing one data item. The control circuitry serially presents K data items for input to the systolic array circuit in synchronization with the clock signals. On the next clock cycle after the control circuitry presents to the systolic array the last of the K data items, the data item of least value in the given subsequence is output.

Abstract: A data center includes a physical host machine operating a virtualized entity and a network switch having a physical port connected to the physical host machine. To configure the network switch, the network switch has a management module that acquires information about the virtualized entity operating on the physical host machine. The network switch associates the acquired information about the virtualized entity with the physical port, assigns the virtualized entity to a group associated with a traffic-handling policy, and processes packet traffic from the virtualized entity in accordance with the traffic-handling policy. The virtualized entity can be, for example, a virtual machine or a multi-queue network input/output adapter operating on the physical host machine.

Abstract: Described are a network device and method for distributing routing information for a virtual private network (VPN) application through a packet-switched network (PSN) from a first provider edge (PE) router to a second provider edge (PE) router. An Ethernet switched path (e.g., a Provider Backbone Transport (PBT) tunnel) is established between the first and second PE routers. The first PE router is at a source end of the Ethernet switched path and the second PE router is at a destination end of the Ethernet switched path. A BGP (Border Gateway Protocol) message is sent from the first PE router to the second PE router. The BGP message contains routing information for a VPN route in a VPN supported by the PSN. An association between the VPN route in the VPN and the Ethernet switched path is determined from the routing information in the BGP message.

Abstract: A multimode home telephone system includes a computer, a base unit, a wireless handset and a wireless headset. The computer is programmed with a "soft phone" program to make and receive VOIP calls via the Internet and couple them to and from the base through a USB connection. The base is also coupled to a public switched telephone network (PSTN) and is operable to effect full duplex communication via both the PSTN and the Internet. The base, in turn, is wirelessly coupled to the handset via the DECT/UPCS protocol, and the handset is wirelessly coupled to the headset via the Bluetooth protocol, such that the user can selectively place and receive telephone calls via any one of the Internet, the PSTN or an optional Bluetooth enabled cell phone. Optionally, a DECT/UPCS enabled headset can communicate directly with the base in addition to or in lieu of the Bluetooth enabled headset.

Abstract: A storage array presents virtual arrays to hosts through use of virtual port IDs. The storage array includes groups of logical units of storage. The groups are coupled to a switch through at least one physical port. Each group is assigned a unique virtual port ID for each physical port to which it is coupled. The virtual port IDs are assignable by the switch. The virtual port IDs are used by hosts coupled to the switch to exchange data with the groups to which the virtual port IDs are assigned. Further, a zoning table in the switch can associate each virtual port ID to a host facing port on the switch. In this case each host can communicate only with groups of logical units that are assigned virtual IDs associated with the host facing port to which it is coupled.
