One of the computers connected to the Arpanet

[2014-10-31] One day before the 45th birthday of the Internet's predecessor Arpanet, 14 nodes communicated via CAN FD during the CAN FD plug-fest. The 15-m network was in line topology with some not terminated stubs. The nodes used an arbitration bit-rate of 500 kbit/s and data-phase bit-rates from 1 Mbit/s to 10 Mbit/s. Of course, this was achieved under laboratory conditions. In the real world with temperatures below zero it might go different. It seems possible to achieve 5 Mbit/s using line topology with daisy-chain connections. For star topologies the bit-rate might be limited to 2 Mbit/s.

The transmission speed of the first Arpanet communication on October 29, 1969 reached only 50 kbit/s, but the network length was several 100 km. I wonder: will anybody still remember CAN FD in 45 years?
