  • Publication number: 20060268732
    Abstract: Data stream protocol analysis using analysis processors. A network processor is connected with a distribution module that distributes network data to multiple memory buffers, each associated with an analysis processor, based at least on a status signal generated by the memory buffers. When the status signal is above a threshold level, the network data is distributed in a different manner or analyzed in a different manner. The analysis processors may begin performing less than a full protocol analysis and perform only selected protocol analysis tests. Some of the network data may be excluded by the network processor from network analysis. In another example, the same network data is sent to multiple analysis processors and each analysis processor performs different protocol analysis tests. Typically, network data corresponding to a particular transaction is sent to the same analysis processor.

  • Publication number: 20060268914
    Abstract: Queue management in performing protocol analysis on network data with multiple analysis processors. Each analysis processor is associated with a memory buffer such as a FIFO queue. Each FIFO queue maintains a status signal representing the fullness of the FIFO queue. The status signal is provided to the analysis processor connected with the FIFO queue and to a network processor that is used in routing the packets of network data. If the status signal indicates that the FIFO queue is too full, then the network processor can redirect the packets to a different analysis processor, begin excluding certain packets from analysis, or controlling the distribution of the packets. Alternatively or at the same time, the analysis processor can begin to restrict which aspects of protocol analysis are performed on the packets of data in the FIFO queue. Full analysis can resume based according to the status signal.

  • Publication number: 20060268860
    Abstract: A network processor used to route network packet to multiple analysis processors for analysis. A network processor is programmable and routes data by receiving the network packets and identifying a transaction of each packet. Each packet is assigned the same transaction identifier by the network processor. A path manager can then send all packets having the same transaction identifier to the same analysis processor. This analysis processors can more easily perform transactional analysis. The network processor also generates control signals that can select the appropriate path for the packets. Alternatively, the transaction identifier and timestamps can be interleaved with the packets for use in distributing the packets to the appropriate analysis processors.

  • Publication number: 20060255487
    Abstract: The bichromal element spinner apparatus provides the forming of substantially spherical bichromal elements from pigmented molten, but hardenable material compounds which are delivered centrally to a spinning webbed disk through opposite ends of hollow shaft that also spins with the disk. The molten materials are injected into cavities formed between the shaft and the web portions of the disk such that the molten materials are spun outwardly on the opposite surfaces of the disk towards the tip of the disk, where the hardenable materials adhere to each other without mixing, thereby spinning off to bichromal elements. Shrouds attached to the shaft and having no intervening support members over the spinning disk provide quiescent air mass between the disk and the shrouds so as to yield bichromal elements with substantial hemispherical integrity.

  • Patent number: 7076010
    Abstract: The current invention provides a method and apparatus for time domain equalization in an XDSL modem. A received communication channel is analyzed to determine the highest frequency component thereof. Typically, there is an inverse relationship between the length of a subscriber line and the highest frequency component over which communications can be supported. In response to the frequency determination, the sampling rate for the channel is reduced to the lowest sample rate consistent with maintaining signal integrity on the highest frequency component of the channel. The sampling rate reduction may accomplished in the analog portion of the receive path, e.g. the analog-to-digital converter (ADC) or in a digital decimator coupled thereto. Concurrently the demodulator complexity is also scaled back. Where the XDSL protocol is digital multi-tone (DMT) the input sample size to the discrete Fourier transform (DFT) engine is reduced accordingly.

  • Patent number: 7076002
    Abstract: The apparatus for symbol boundary synchronization in one embodiment includes on the receive path of a multi-tone modem a window synchronizer, a converter and a symbol boundary component. The window synchronizer obtains windowed portions of the received datastream which includes symbols each expressed with a corresponding set of tones in a time domain. The windowed portions obtained in the training phase exhibit varying degrees of misalignment with the corresponding symbol boundaries. The window synchronizer is responsive to an alignment signal to obtain succeeding windowed portions of the incoming datastream aligned with the corresponding symbol boundaries therein. The converter couples to the window synchronizer to convert the set of tones from each windowed portion from the time domain to a frequency domain.
