Abstract:
1. A method for monitoring flows of packets over a network, wherein a network computer executing the method performs actions, comprising: employing the network computer to normalize Open Systems Interconnection (OSI) model information for layer 4 included in each header of each received packet, wherein normalizing layer 4 OSI model information by masking an acknowledgment number value and a checksum value for a header of the layer 4 OSI model information in each received packet; when at least a value based on the normalized layer information for a header of a packet is determined to be equivalent to another value based on normalized layer information for another header of another subsequently received packet, determining the other subsequently received packet as duplicative of the packet; and monitoring at least one flow of received packets, wherein each packet that is determined to be duplicative is processed separate from monitoring the at least one flow of received packets that are determined to be non-duplicative.
