摘要： A packet processing pipeline is configured to classify packets received via a network based on information in the received packets: (1) as belonging to one of a plurality of identified flows, or (2) as not belonging to any of the plurality of identified flows. For each received packet determined not to belong to one of the previously identified flows, the pipeline sends at least a portion of the packet or a corresponding packet descriptor to a processing unit. For each received packet determined not to belong to one of the previously identified flows, the processing unit defines a new flow corresponding to the packet based on an analysis of the portion corresponding packet descriptor, and configures the packet processing pipeline to handle the new flow.
