Abstract
Traffic differentiator systems for network devices and related methods are disclosed that determine difference packets from multiple packet streams. Some embodiments are configured to receive two streams of packets with one stream being a processed version of another stream and then to determine difference packets within a lookup time window that is, for example, associated with a processing time for the second stream to be a processed version of the first stream. Difference packets within a lookup time window can also be determined for packets received within a single combined stream of packets. Difference packets and/or related statistical information is then output for additional processing, as desired. The streams of packets can be associated with ingress and egress packets for a network device, and the difference packets and related statistical information can be used to determine packets that are removed, added, and/or modified by the network device.
