<p>The invention relates to a method for discovering the level-3 IP topology of an internet network (2) including a step (110) of determining an initial subnetwork (6) to which a discovery terminal (3) is connected. The method comprises steps comprising, in a recursive loop of common path parameters (Nbsauts), searching the subnetworks (34, 36, 38, 40, 42, 44) with the same subnetwork rank (Nbsauts) from all the subnetworks (18, 20, 22) with a rank immediately lower by a number one than the common value (Nbsauts), the rank of a subnetwork being the minimum number of routers required to access said subnetwork from a discovery terminal, and assigning the common value of the common path parameter (Nbsaut) as subnetwork rank to the predetermined subnetworks (34, 36, 38, 40, 42, 44) with the same subnetwork rank (Nbsauts).</p> |
