Abstract: A networking device includes a packet header protect generator, a transmitter, a receiver, a decoder and router. The transmitter transmits a data packet to the receiver. The data packet includes a data packet header. The packet header protection generator is arranged to toggle selected bits of a protected portion of the data packet header and generate a data integrity signature. The receiver receives the data packet and generates a received data integrity signature. The decoder computes a locally computed data integrity signature in response to the protected portion of the received data packet header. The locally computed data integrity signature is compared with the received data integrity signature. The router selects a portion of a routing path in response to whether a data packet forwarding destination includes a decoder arranged to compute a locally computed data integrity signature.

Abstract: A packet header protection system includes, for example, a header checksum (CS) that is arranged to provide error detection capability to FSK (frequency shift keyed) packet headers. Accordingly, receivers in the network can more quickly terminate processing of an errored packet upon detection of error(s) in the header. Quickly detecting packet header errors helps to avoid a sequence of compounding errors such as the repeated transmissions of a packet having an undetected erroneous header. Accordingly, the packet header protection system reduces false alarm rate in the network and increases network throughput.
