Abstract
A method and system for automatically determining priority data streams on a computer network. A data traffic signature is calculated for a data stream using one or more of an average packet spacing, average packet size, average packet jitter or variation in packet size parameters calculated for data packets in a data stream. An optimized data signature can also be calculated for a data stream using one or more of an optimized average packet spacing, optimized average packet size, optimized average packet jitter or optimized variation in packet size parameters. A calculated data traffic signature is used to determine whether the calculated data traffic signature matches a known data traffic signature for a known type of data stream. If a calculated data traffic signature matches a known data traffic signature for a known type of data stream, such as a multimedia data stream, resources are allocated on a network device to provide a desired processing priority to data packets in the data stream. Data packets in a higher priority data stream associated with a calculated data traffic signature are sent and received before any other data packets from other data streams with a lower proc…
