The invention facilitates the distribution of content over a network (e.g., the Internet, a television network) and, in particular, the distribution of high-bandwidth (i.e., data intensive) content, such as video content or customized content. At least one of the sites of the network (a “core server”) is controlled (at least in part) by an entity that desires to distribute content to one or more other network sites (“client(s)”) at which the content is to be used. In accordance with the invention, a core server uses one or more other network sites (“node server(s)”) to distribute content on behalf of the core server to one or more clients. In particular, in accordance with one embodiment of the invention, the entit(ies) having control (at least in part) of each of one or more network sites (node server(s)) can be recruited to use their site(s) to distribute content on behalf of a core server to one or more clients.

A Data Center Ethernet (“DCE”) network and related methods and device are provided. A DCE network simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet, storage and other traffic. A Fibre Channel (“FC”) frame, including FC addressing information, is encapsulated in an Ethernet frame for transmission on a Data Center Ethernet (“DCE”) network. The Ethernet address fields may indicate that the frame includes an FC frame, e.g., by the use of a predetermined Organization Unique Identifier (“OUI”) code in the D_MAC field, but also include Ethernet addressing information. Accordingly, the encapsulated frames can be forwarded properly by switches in the DCE network whether or not these switches are configured for operation according to the FC protocol. Accordingly, only a subset of Ethernet switches in the DCE network needs to be FC-enabled. Only switches so configured will require an FC Domain_ID.

The present invention is drawn to an electrically “closed” method and apparatus for transmitting and receiving data signals over a high voltage power line. Inductive coupling is employed for coupling and decoupling the data signal directly on to and off of a single power line wire. An exemplary device includes a high frequency inductive coupling toroid for data signals, a second (50-60 Hz) inductive coupling toroid for providing power, signal conditioning electronics for the receive and transmit signal, a fiber optics interface for electrical isolation purposes, and a weather-proof enclosure. In a preferred embodiment, the toroids are hinged for ease of installation on a power line. A pair of such couplings on either side of a fiber-optic isolator can be used to bridge transformers.

Streaming video data from the video title is delivered to a client from a central server and a proxy server. To reduce the backbone bandwidth required, a portion of the video title is cached at the proxy server where the portion cached is distributed over the video title so as to reduce the peak bit rate required for the central server to send the remaining portion of the video title. The amount cached at the proxy server may be adjusted in accordance with access profile of video titles to improve caching efficiency. The portion cached may be the basic layer in a scalable multilayer approach where only the basic layer may be sent to a client who has limited bandwidth while clients with higher bandwidth capability may also receive the enhancement layer(s) for improved video reception.

Flow-aware task distribution in network devices having multiple processor architectures. In one embodiment, the present invention can be used for high bandwidth network processing in an application and flow aware Quality of Service (QoS) network device. In some implementations, the present invention provides a task distribution architecture capable of flow state awareness and link level QoS control. In some implementations, the present invention can incorporate one or more processes, such as flow distributors and device distributors, that route packets for processing among different processing units on the basis flow correspondence and/or link or network path attributes. The flow and device distributors, in one implementation, allow for the separation and paralletization of packet processing functionality into flow-specific and link-specific processing units, allowing for a highly-scalable, flow-aware task distribution in a network device that processes network application traffic.

A robotic device can provide power management and other functionality for various electronic devices. An electronic device and the robotic device can communicate information such as device charge level, relative position and rate of power consumption and can determine an appropriate time at which the robotic device should cause the electronic device to be charged, either by charging the device directly or transporting the device to an appropriate charger. The robotic device can also cause other functions to be performed as well, such as to enable high-bandwidth data transfer or perform resource-intensive activities when in communication with the electronic device. The robotic device can transport the electronic device to specific locations or to specific users, or as otherwise appropriate.

Described herein is a probe card assembly providing signal paths for conveying high frequency signals between bond pads of an integrated circuit (IC) and an IC tester. The frequency response of the probe card assembly is optimized by appropriately distributing, adjusting and impedance matching resistive, capacitive and inductive impedance values along the signal paths so that the interconnect system behaves as an appropriately tuned Butterworth or Chebyshev filter.

Disclosed is a method and apparatus to continuously transmit high bandwidth, real-time data, on a communications network (e.g., wired, wireless, and a combination of wired and wireless segments). A control computing device uses user or application requirements to dynamically adjust the throughput of the system to match the bandwidth of the communications network being used, so that data latency is minimized. An operator can visualize the instantaneous characteristic of the link and, if necessary, make a tradeoff between the latency and resolution of the data to help maintain the real-time nature of the system and better utilize the available network resources. Automated control strategies have also been implemented into the system to enable dynamic adjustments of the system throughput to minimize latency while maximizing data resolution. Several applications have been cited in which latency minimization techniques can be employed for enhanced dynamic performance.

A new general method for building hybrid processors achieves higher performance in applications by allowing more powerful, tightly-coupled instruction set extensions to be implemented in reconfigurable logic. New instructions set configurations can be discovered and designed by automatic and semi-automatic methods. Improved reconfigurable execution units support deep pipelining, addition of additional registers and register files, compound instructions with many source and destination registers and wide data paths. New interface methods allow lower latency, higher bandwidth connections between hybrid processors and other logic.

In next generation wireless networks such as a Mobile WiMAX traffic prioritization is used to provide differentiated quality of service (QoS). Unnecessary ping-pong handovers that result from premature reaction to fluctuating radio resources pose a great threat to the QoS of delay sensitive connections such as VoIP which are sensitive to scanning and require heavy handover mechanisms. Traffic-class-specific variables are defined to tolerate unbalance in the radio system in order to avoid making the system slow to react to traffic variations and decreasing system wide resource utilization. By setting thresholds to trigger load balancing gradually in fluctuating environment the delay sensitive connections avoid unnecessary handovers and the delay tolerant connections have a chance to react to the load increase and get higher bandwidth from a less congested BS. A framework for the resolution of static user terminals in the overlapping area within adjacent cells will be described.

A wireless communication system is provided that has at least three nodes arranged in a multi-hop ultra wide band (UWB) communication network such that communications from a first node destined for a third node pass through a second node. Each of the devices in the system includes a radio and a media access control (“MAC”) module that is configured to establish multi-hop UWB wireless communications between the three or more wireless communication devices that enables high bandwidth applications such as Voice Over Internet Protocol (“VoIP”); multiplayer gaming; Wireless High Definition Television; and Internet Protocol Television (“IPTV”) among others. The MAC module is configured to avoid bandwidth reservation conflicts so that network performance does not degrade as the number of hops or the number of nodes in the wireless communication system increases. The MAC also facilitates utilization of multiple channels to maximize the available spectrum and is further configured to dynamically switch between channels to maximize throughput and meet or exceed quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized.

A dual-band antenna is provided that combines two normally disparate communications modes into a single compact aperture minimizing overall mass and volume, while maintaining high performance efficiency and reciprocity of each individual mode. The antenna is compatible with both optical (near-IR/visible) and RF (microwave/millimeter-wave) transceiver subsystems for high bandwidth communications, applicable primarily to long- to extremely long-range (space-to-ground) link distances. The optical link provides high bandwidth while the RF provides a lower data-rate weather backup, accommodation for traditional navigation techniques, and assistance in cueing the extremely tight optical beam by matching the RF beamwidth to an optical fine-steering mechanism field-of-regard. The configuration is built around a near-diffraction-limited high performance primary mirror shared by both a direct-fed RF antenna design and a Cassegrain optical telescope. Material properties are exploited to combine the optical secondary mirror with the RF feed structure, providing a collimated optical beam interface at the antenna vertex.

A computer system includes a controller coupled to a plurality of memory modules each of which includes a memory hub and a plurality of memory devices divided into a plurality of ranks. The memory hub is operable to configure the memory module to simultaneously address any number of ranks to operate in a high bandwidth mode, a high memory depth mode, or any combination of such modes.

A mobile backhaul inter-mesh communication point forms an interface between a wireless mesh network on a first level and a wireless mesh network on a second, higher bandwidth, level. The two wireless networks are differentiated, e.g., by causing the mesh networks to be formed using different spectra, protocols or coding, or antennae. The mobile intra-mesh communication point functions as an access point in the lower level mesh network and as a relay point in the upper level mesh network. Utilizing mobile inter-mesh communication points facilitates deployment of wireless network access points while enabling the location of access points to follow the concentration of network users. Mobile inter-mesh communication points may be deployed in personal vehicles such as cars, trucks, and motorcycles, public transportation vehicles such as busses, trains, and aircraft, emergency vehicles such as fire trucks and ambulances, and many other types of vehicles.

The present invention provides a motherboard that uses a high-speed, scalable system bus such as PCI Express® to support two or more high bandwidth graphics slots, each capable of supporting an off-the-shelf video controller. The lanes from the motherboard chipset may be directly routed to two or more graphics slots. For instance, the chipset may route (1) thirty-two lanes into two ×16 graphics slots; (2) twenty-four lanes into one ×16 graphics slot and one ×8 graphics slot (the ×8 slot using the same physical connector as a ×16 graphics slot but with only eight active lanes); or (3) sixteen lanes into two ×8 graphics slots (again, physically similar to a ×16 graphics slot but with only eight active lanes). Alternatively, a switch can convert sixteen lanes coming from the chipset root complex into two ×16 links that connect to two ×16 graphics slots. Each and every embodiment of the present invention is agnostic to a specific chipset.

A high-speed ring topology. In one embodiment, two base chip types are required: a "drawing" chip, LoopDraw, and an "interface" chip, LoopInterface. Each of these chips have a set of pins that supports an identical high speed point to point unidirectional input and output ring interconnect interface: the LoopLink. The LoopDraw chip uses additional pins to connect to several standard memories that form a high bandwidth local memory sub-system. The LoopInterface chip uses additional pins to support a high speed host computer host interface, at least one video output interface, and possibly also additional non-local interconnects to other LoopInterface chip(s).

The present invention can be used in conjunction with telephony applications, cable tv applications, and data bus applications.

Solid State Drives (SSD) can yield very high performance if it is designed properly. A SSD typically includes both a front end that interfaces with the host and a back end that interfaces with the flash media. Typically SSDs include flash media that is designed with a high degree of parallelism that can support a very high bandwidth on input/output (I/O). A SSD front end designed according to a traditional hard disk drive (HDD) model will not be able to take advantage of the high performance offered by the typical flash media. Embodiments of the invention provide improved management of multiple I/O threads that take advantage of the high performing and concurrent nature of the back end media, so the resulting storage system can achieve a very high performance.
