Assignee: SONAS, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A communication apparatus comprising an input unit configured to input data, a control unit configured to generate a packet including the data, a transmission unit configured to transmit the packet, and a reception unit configured to receive a packet,
wherein when transmitting the data input to the input unit, the control unit generates a first error detection code for at least the data and a second error detection code for at least the data, timing information corresponding to a transmission timing of the packet, and the first error detection code, and generates the packet including the data, the timing information, the first error detection code, and the second error detection code, and
when relaying the packet received by the reception unit, the control unit performs error detection based on the second error detection code included in the received packet, and discards the received packet if an error is detected, and updates the second error detection code and reconstructs the packet if no error is detected,
wherein the second error detection code is generated for all data except for the second error detection code in the packet, and the first error detection code is generated for at least part of all data except for the timing information, the first error detection code, and the second error detection code in the packet.
