Abstract:
1. A method for monitoring flows of packets over a network, wherein a network device enables actions, comprising: passively receiving packets communicated over at least one network; determining Open Systems Interconnection (OSI) model layer 2 and layer 3 (layer 2-3) information included in each header of each received packet; normalizing layer 2-3 information in each header of each received packet; if at least a value based on normalized layer 2-3 information for a header of a packet is determined to be equivalent to another value based on normalized layer 2-3 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 the at least one monitored flow's packets are identified as non-duplicative, and wherein each packet that is determined as duplicative is subsequently processed separate from monitoring the at least one flow of received packets.
