Abstract (en)

[origin: CA2591909A1] The invention relates to a method for duplicating a database in a network of machine, and to a system of machines comprising a duplicated database. Said machines (1, 2, 3) share the same database (10) which is duplicated in the machines. A first machine (1) transmits data (A) updated in the database thereof to the other machines (2, 3). A master machine (31) converges the databases (10) between the machines. To this end, the machine (1) transmitti ng the data (A) emits, in the same message as the data (A), the version number thereof and the address of the machine; the machine (1) also emits the messa ge to a master machine (31); a machine (31, 2, 3) publishes the data (A) in the database (10) thereof, following a version number test; and the master machi ne (31) emits a central announcement message (32, MAC) to the machines (1, 2, 3 ), said central announcement message comprising the version number thereof for all of the data in the database (10), and the address of the machine (1) at the origin of the updating thereof. The invention especially applies to the duplication of databases in a large number of machines connected in a networ k, for example in air traffic management systems.
