nine packets

IP over Avian Carrier (IPoAC) is a real IP transmission protocol, and has been implemented at least once.

IPoAC has been successfully implemented, but for only nine packets of data, with a packet loss ratio of 55% (due to operator error),[2] and a response time ranging from 3000 seconds (≈54 minutes) to over 6000 seconds (≈1.77 hours). Thus, this technology suffers from poor latency.

If 16 homing pigeons are given eight 512 GB SD cards each, and take an hour to reach their destination, the throughput of the transfer would be 145.6 Gbit/s
