Central Databases 1

• Needed primarily to enable Call Sign Routing to a
  specific station
• US Trust is the first
• 1 database for the world
• Sometimes slow to update
• No cleanup so becomes corrupted
• Poorly documented, closed, closely-guarded
  secrets
• Fragile
• Also has dplus server database to keep track of
• Multi Trust was the second
• distributed data amongst several strategic
  servers
• Much faster than US Trust
• European servers removed when ircDDB came along
• North American Trust remains as a scaled down
  version
• dextra based
• Now uses ircDDB

Central Databases 2

• ircDDB
• central redundant database
• data is rcvd by gateway using IRCclient in Java
  using RFC2812
• data is sent by gateway using dsm
• no interference w USTrust database or dplus
  database
• open source
• fast
• Dutch
• dpns or d-Plus name server by Fred van Kempen
  PA4YBR
• Alternative to the dplus database (which only
  shows Icom systems)
• permits hot spots, dvdongles, dvaps to see
  registered hot spots as well as Icom and non-Icom
  gateways
• Does not interfere with other databases
