  • Admission control in networked services
    Publication number: 20040114514
    Abstract: Prediction-based online admission control for incoming jobs has an explicit objective of optimizing a utility function. The input to an algorithmic procedure is a set of requests made in respect of a network service. Each request has information about the length of the request. An output of the algorithmic procedure is a selected subset of requests that can be served within the capacity constraints of the network service, such that the utility function is approximately optimized (for example, minimized or maximized) depending on the context of the particular application.

  • METHOD AND APPARATUS FOR ERROR DATA RECOVERY
    Publication number: 20030212944
    Abstract: The present invention provides a mechanism for preventing quality degradation of decoded data during the decoding of encoded data. In one embodiment, error propagation is detected and corresponding data is flagged. An error recovery process is then applied to the flagged data. In an alternate embodiment, scores for candidate hypotheses are calculated for lost/damaged data. A score distribution is used for detection of the false candidate hypotheses. The data are flagged if their score distribution is within a range defined by a threshold and an error recovery process is applied to recover those data having associated error flags set.
