Global datagram carriage over biological transport, fully conformant with RFC 1149. Field-proven since 2001 with an industry-defining packet delivery rate of 44.5%.
IP datagrams printed on paper, affixed to the carrier's leg, and released in the general direction of the destination.
Quality of Service for demanding workloads. Priority packets travel by a carrier that has been fed slightly better.
Full 128-bit addressing support. Requires a larger card, a stronger carrier, and a customer who has genuinely deployed IPv6.
Figures from the Bergen field implementation, April 2001. Nine packets sent, four delivered. These are real results from a real deployment, and we have not attempted to improve on them since.
