    摘要: A scalable method and apparatus that detects frequent and dispersed invariants is disclosed. More particularly, the application discloses a system that can simultaneously track frequency rates and dispersion criteria of unknown invariants. In other words, the application discloses an invariant detection system implemented in hardware (and/or software) that allows detection of invariants (e.g., byte sequences) that are highly prevalent (e.g., repeating with a high frequency) and dispersed (e.g., originating from many sources and destined to many destinations).

    摘要: A device includes a multistage filter and an elephant trap. The multistage filter has hash functions and an array. The multistage filter is operable to receive a packet associated with a candidate heavy network user and send the packet to the hash functions. The hash functions generate hash function output values corresponding to indices in the array. The elephant trap is connected to the multistage filter. The elephant trap includes a buffer and probabilistic sampling logic. The probabilistic sampling logic is operable to attempt to add information associated with the packet to the buffer a particular percentage of the time based in part on the result of the multistage filter lookup. The buffer is operable to hold information associated with the packet, counter information, and timestamp information.

    摘要: In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.
