Technologies for adaptive routing using throughput estimation that includes a network switch. The network switch is configured to determine an adjusted average saturation count for each output buffer queue as a function of a present value of a saturation counter of a corresponding output buffer queue and a weighted average saturation count and a running average saturation count for each of the plurality of output buffer queues as a function of the corresponding captured present value and the adjusted average saturation count. The network switch is further configured to determine a congestion rate value for each output buffer queue and a total congestion value as a function of the congestion rate values and a standard occupancy congestion corresponding to a respective one of the plurality of output buffer queues. Other embodiments are described herein.

Technologies for adaptive routing based on network traffic pattern characterization include a network switch configured to receive a network packet via one of a plurality of input ports and identify a set of the plurality of output ports associated with a path usable to forward the received network packet to a destination computing device along. The network switch is further configured to adjust a total congestion value for each of the set of output ports based on a type of the path to which each of the set of output ports corresponds and a value of a minimal path counter to which each of the set of output ports corresponds and enqueue the received network packet into an output buffer queue of one of the set of output ports based on the total congestion value. Other embodiments are described herein.
摘要:
Technologies for increasing the bandwidth of partitioned hierarchical networks is disclosed. If each partition of network groups of a computer network are isolated, then the connections between the network groups of different partitions may go unused. However, careful selection of the network connections between partitions of different network groups may allow for a pseudo-direct connection between two network groups of the same partition using a single non-blocking switch in a network group of a different partition. Such a configuration can increase the effective bandwidth available within a partition without affecting the bandwidth available in another partition.

A high-resolution, patterned-media master mask is disclosed. The high-resolution, patterned-media master mask includes an electron-absorption substrate for absorbing electrons from an electron beam (e-beam) during an e-beam exposure by an e-beam lithography process and suppressing a backscattering of the electrons based on an electron-backscattering-suppressing atomic number associated with a constituent atomic species of the electron-absorption substrate, wherein the electron-absorption substrate comprises a material composed of greater than fifty atomic percent of the constituent atomic species, and wherein the electron backscattering-suppressing atomic number is less than an atomic number eight. The high-resolution, patterned-media master mask further includes a patterned portion coupled with the electron-absorption substrate, wherein the patterned portion is patterned by the e-beam lithography process, and wherein a resolution of the patterned portion is increased in response to the electron-absorption substrate suppressing the backscattering of the electrons.

A thin film lead structure resistant to resistance increase phenomenon resulting from contamination by mobile impurities. A thin film lead is disposed proximate to a getter layer material having a higher affinity for mobile impurities that the thin film lead. The getter layer material captures mobile impurities and prevents their migration into the thin film lead. The getter layer material may be formed over and in contact with the thin film lead, may be encapsulated within the thin film lead, or both. The getter layer material comprises a rare earth metal selected from the group consisting of yttrium, scandium, lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, erbium, and ytterbium. The thin film lead is preferably tantalum, but may be selected from the group consisting of niobium, vanadium, chromium, molybdenum, tungsten and iron. An alternate embodiment of the invention includes a transition metal comprising titanium, zirconium, or hafnium as the getter layer. The capture of mobile impurities by the getter layer prevents resistance increase phenomenon and embrittlement to the thin film lead. The thin film lead may be used as a thin film lead to an electrical circuit, the sensor structure in a magnetic head.
摘要:
Video signals from a source are digitized and applied to a source coder which segregates the signals into four channels (CH1 to CH4) of progressively less visual significance. CH1 carries basic picture information at a relatively low resolution. CH2 to CH4 carry differential information at progressively higher resolutions. The four channels signals are applied to respective coders and the digital outputs are combined in a matrix with voltage levels falling off as visual significance decreases. Received signals, transmitted say by way of a satellite, are applied to a first, high level decoder which extracts the digital waveform for CH1 as DCH1. This is recoded and subtracted from the input to provide a signal to a decoder which recovers CH2 as DCH2, and so on. DCH1 to DCH4 are applied to a source decoder complementary to the coder to recover the source signal. Low significant channels can be omitted at the transmitter, or not be recovered at the receiver to adapt to the prevailing signal to noise performance.

摘要:
Optical laser amplifier devices are formed integrally with spontaneous emission filters. The filtering function is accomplished by a laser amplifier whose output is employed to quench the signal generated by a laser. The quenching of the laser is performed in direct proportion to the stimulated emission component of the laser amplifier output signal. Since the stimulated emission component represents the output signal minus any spontaneous emission noise, the output signal generated by the laser is an amplified, inverted version of the input signal without the noise components. In the preferred embodiments, optical waveguides are employed to form the laser amplifier and the laser is either a horizontal cavity edge emitting laser or a vertical cavity surface emitting laser (VCSEL).
