Methods and apparatus for detecting and limiting focused server overload in a network
InactiveUS20100274893A1Low transfer rateReduce in quantityEnergy efficient ICTDigital computer detailsHash functionComputer program
Computer-based methods and apparatuses, including computer program products, are described for detecting and limiting focused server overload in a network. A feedback message is received from a downstream server, wherein the feedback message includes a communication protocol statistic. The methods and apparatuses determine which of one or more counters that store a number of feedback messages received that include the statistic, from an array of counters, are associated with the downstream server using one or more hash functions based on information included in the feedback message. The one or more counters are incremented in response to the feedback message including the statistic. Using the one or more hash functions, a value of the number stored in the one or more counters is determined. The value is determined to be indicative of an overload episode in the network for the downstream server based on whether the value satisfies a predetermined criteria.

Smooth silicon and silicon germanium films are deposited by plasma enhanced chemical vapor deposition (PECVD). The films are characterized by roughness (Ra) of less than about 4 Å. In some embodiments, smooth silicon films are undoped and doped polycrystalline silicon films. The dopants can include boron, phosphorus, and arsenic. In some embodiments the smooth polycrystalline silicon films are also highly conductive. For example, boron-doped polycrystalline silicon films having resistivity of less than about 0.015 Ohm cm and Ra of less than about 4 Å can be deposited by PECVD. In some embodiments smooth silicon films are incorporated into stacks of alternating layers of doped and undoped polysilicon, or into stacks of alternating layers of silicon oxide and doped polysilicon employed in memory devices. Smooth films can be deposited using a process gas having a low concentration of silicon-containing precursor and / or a process gas comprising a silicon-containing precursor and H2.
