(9448) Donaldavies Main-belt Asteroid
Discovered on 5 June 1997 by Spacewatch at Kitt Peak.
Donald W. Davies (1925-2000), a British expert in computer security, suggested in 1965 a robust multipath network between computers to divide data into small labeled packets and transmit them, on different paths if necessary, for reassembly at their destination. This is the basis for TCP-IP protocol in Internet communications.Naming citation (20001111/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
