APPENDIX B. EXAMPLE UDP/IP DATA INTERFACE CONFIGURATION
In the figure below an example use case of the CDNA is shown where one GOE (ECU #1 unit is configured for 1 Channel of Uplink,
and 1 Channel of Downlink. The second ECU and channels[2-3] are not shown for clarity, but could be configured for UDP/IP or
TCP/IP modes independently of channels[0-2]
In this example the CDNA channels [0-1] are running 2 embedded UCP/IP servers and clients, with 4 UDP/IP ports (PT[0:1], and
CT[0:1]).
Channel[0] PT & CT are set to Encrypt direction in UDP-GCM mode. The External client sends in UDP/IP packets with a fixed 20B
Bypass header to the PT[0] at IP:PORT 169.254.100.100:64000. Data is encrypted, and bypass data is passed through internally to
the CT[0] channel. The CT[0] channel is set to multicast, so it sends the output encrypted UDP/IP with fixed 20B Bypass to the two
programmed destinations UDP servers at IP: 169.254.100.203:64004, and 169.254.100.204:64004 respectively.
Channel[1] PT & CT are set to Decrypt direction in UDP-GCM mode. The External client sends in UDP/IP packets with a fixed 20B
Bypass header to the CT[1] at IP:PORT 169.254.100.102:64004. Data is decrypted, and bypass data is passed through internally to
the PT[1] channel. The PT[1] channel is set to multicast, so it sends the output encrypted UDP/IP with fixed 20B Bypass to the two
programmed destinations UDP servers at IP: 169.254.100.205:64001, and 169.254.100.206:64001 respectively.
