Patent ID: 8693308

Claim:
A method for resilient packet communications in a wireless network, the method comprising: instantiating a hardware-assisted rapid transport channel failure detection algorithm in a data access card, to: configure the data access card to process a packet with an extended header field that contains a transmit status and a receive status, wherein the receive status indicates a status of receiving of a first node of the wireless network and the transmit status indicates a status of receiving of a second node of the wireless network, the transmit status being a reflection of a second node receive status indicator that is conveyed in a header of a received packet, the receive status being computed based on information obtained from a traffic alignment indicator and the integrity of received packets; and configure the data access card to perform failure detection at a physical layer and perform recovery operations of the wireless network, the data access card being configured to perform the recovery operations within a data layer, the recovery operations being based, at least in part, on the transmit status or receive status in the extended header field.
