Systems and methods are disclosed for parallel match processing of network packets to identify data for masking or other actions. In part, the disclosed embodiments receive packets and identify packet data, such as sensitive data, by rapid parallel matching of packet data being communicated in multi-byte wide data paths to match parameters in order to generate match vectors. The match vectors are then used to generate control vectors that are subsequently used by packet processing circuitry to perform desired actions for this packet data (e.g., mask data) and/or for related packets (e.g., drop packets). For example, data identified through the match processing can be masked, and control vectors can be mask control vectors applied to parallel multiplexers. In certain embodiments, the parallel data multiplexers are controlled by the mask control vectors to selectively output either original packet data or mask data that obscures original packet data.

Power entry and distribution for network communication systems are disclosed. For certain embodiments depicted, a power distribution board with an open-grid configuration receives power feed/return lines from a power entry connector and distributes the power feed/return lines for a network processing system. The open-grid configuration facilitates airflow through a chassis and thereby provides improved cooling. Further, a modular power entry connector can be used to facilitate connection of power feed/return cables to the chassis for the network processing systems while improving safety for high power implementations.

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.
