Abstract:
1. A device, comprising: reception circuitry adapted to receive a data unit from a first node of a network and a confirmation message signal from a second, different node of the network, wherein the confirmation message signal indicates that the second node correctly received the data unit, analysis circuitry adapted to determine a failure to correctly receive the data unit by the reception circuitry of the device; and transmission circuitry adapted to transmit a negative acknowledgement signal to the first node in case the analysis circuitry determines the data unit has not been correctly received by the reception circuitry of the device and the confirmation message signal from the second node is received by the reception circuitry of the device; wherein at least one of the reception circuitry, analysis circuitry, and transmission circuitry are implemented in hardware.
