Methods and apparatus for selecting a server to process a request

The invention is directed to techniques for selecting a resource from several resources to process a request from a client. A client sends the request to a data communications device (e.g., network device or switch), which measures usage information from usage meters associated with each resource (e.g., server). The data communications device then makes a usage estimate for each server of the increase in usage required for that server to process the request from the client. Then the data communications device selects one of the servers depending on the usage estimates required to respond to the client's request. The data communications device can consider other factors such as the current level of usage, past usage, and the increased cost of responding to the request. In addition, the data communications device can consider the peak usage level of each resource already established in a current billing period.

Method and coding means for error-correction utilizing concatenated parity and turbo codes

A method and apparatus for encoding and decoding data using an overall code comprising an outer parity-check and an inner parallel concatenated convolutional, or turbo code. The overall code provides error probabilities that are significantly lower than can be achieved by using turbo codes alone. The output of the inner code can be punctured to maintain the same turbo code rate as the turbo code encoding without the outer code. Multiple parity-check codes can be concatanated either serially or in parallel as outer codes. Decoding can be performed with iterative a posteriori probability (APP) decoders or with other decoders, depending on the requirements of the system. The parity-check code can be applied to a subset of the bits to achieve unequal error protection. Moreover, the techniques presented can be mapped to higher order modulation schemes to achieve improved power and bandwidth efficiency.

Process for the preparation of polyalkenyl succinic anhydrides

A polyalkenyl succinic anhydride is prepared with low amounts of resinous or chlorinated byproducts in a two-step process whereby a polyalkene is first reacted with an unsaturated organic acid in a thermal ene reaction, followed with exposure to a gaseous halogen in presence of an additional amount of the unsaturated organic acidic reagent. The foregoing process produces a polyisobutenyl succinic anhydride having a high ratio of succinic anhydride functional groups to polyisobutenyl backbone groups. Such a polyisobutenyl succinic anhydride is particular suitable for the production of oil-soluble hydrocarbyl succinimides that have good dispersant properties when added to lubricating oil compositions.

System for controlling and enforcing playback restrictions for a media file by splitting the media file into usable and unusable portions for playback

Files are divided into parts and at least some of the parts are transmitted to a client using a communication channel. At least some of the transmitted parts are cached locally. This allows subsequent streaming playback of the file while using less bandwidth by transmitting the part of the file that hasn't been cached, and combining the cached parts with the transmitted parts. In some embodiments, files may be represented at a low quality level by a first data set, and at higher quality levels with additional data sets. Data sets are cached locally, so that during subsequent streaming playback of the file, the quality level of the playback may be improved by sending additional data sets using bandwidth that would otherwise be dedicated to transmitting the cached data sets.

Topology and control method for power factor correction

In a power factor corrected AC-to-DC power supply system, a DC-to-DC power converter is coupled to the output of an AC-to-DC power converter in order to produce a regulated DC output signal from a rectified AC input signal. The AC-to-DC power converter and the DC-to-DC power converter each includes a switch for controlling the operation of their respective power converter. The AC-to-DC converter includes an inductor. The system provides power factor correction for minimizing harmonic distortion by including a controller that receives the regulated DC output voltage as a feedback signal, and in response, produces a series of drive pulses having predetermined constant duty cycle. These pulses are simultaneously fed to each switch, to operate the respective converters alternately between ON and OFF states. When the AC-to-DC converter is driven by a fixed duty cycle of the series of pulses, power factor correction is improved since the current flowing through the inductor is substantially proportional to the waveform of the rectified AC input signal. By preselecting the value of the inductor, the AC-to-DC converter is operable in a discontinuous mode when the instantaneous rectified AC input signal is low and in a continuous mode when the instantaneous rectified AC input signal is high.
