    摘要: In accordance with one aspect of the invention, a selector supports the selection of a first encoding scheme or the second encoding scheme based upon the detection or absence of the triggering characteristic in the interval of the input speech signal. The first encoding scheme has a pitch pre-processing procedure for processing the input speech signal to form a revised speech signal biased toward an ideal voiced and stationary characteristic. The pre-processing procedure allows the encoder to fully capture the benefits of a bandwidth-efficient, long-term predictive procedure for a greater amount of speech components of an input speech signal than would otherwise be possible. In accordance with another aspect of the invention, the second encoding scheme entails a long-term prediction mode for encoding the pitch on a sub-frame by sub-frame basis. The long-term prediction mode is tailored to where the generally periodic component of the speech is generally not stationary or less than completely periodic and requires greater frequency of updates from the adaptive codebook to achieve a desired perceptual quality of the reproduced speech under a long-term predictive procedure.

    摘要: A managed network with a quarantine enforcement policy based on the status of installed updates for software on each client seeking access to the managed network. To determine whether a client requesting access has up-to-date software, an access server may communicate directly with an update server to determine the update status of the client requesting access. Information from the update server allows the update server to determine which update the client requesting access is missing. The access server may also receive an indication of the severity of the updates missing from the client requesting access. The access server may use the severity information to apply a quarantine enforcement policy, thereby avoiding the need for either the client or access server to be programmed to identify specific software updates that must be installed for a client to comply with a quarantine enforcement policy. To reduce network congestion and delays seeking access to the network, the quarantine enforcement policy includes a deadline by which updates must be installed. Establishing a deadline allows a grace period during which clients may download new updates and avoids network congestion from multiple clients downloading updates simultaneously.
