Abstract: The present invention provides a method of determining or selecting a path for transmitting data in packets in an Internet Protocol communication network and a communication network using the method. The method comprises predetermining a limited number of paths by repeatedly applying a single criterion selection method to all of the paths in the network concerned, using different first criteria, and then determining one or more given paths from said limited number of predetermined paths by comparing them with each other on the basis of two or more conditional criteria and then classifying them.

Abstract: A router (R) for a distributed routing communications network includes i) a database (BD1-BD3) containing data representing states of links between routers of the network, ii) calculation means (MC) adapted to determine routes from the data and to update distributed routing tables as a function of the determined routes, and iii) management means (MG) adapted, in the event of local reception or transmission of an LSA or a TE-LSA at a time TAL(R), to determine the elapsed time (T_e) from the reception or transmission of the last instance of the LSA or the TE-LSA in order to compare it to a selected threshold and either to await the expiry of a current calculation delay (OPC) in the presence of a TE-LSA or to trigger a stabilization delay of selected duration and the starting time TAL(R) of which serves to resynchronize the expiry time of the current calculation delay to a selected time in the presence of a bursty TE-LSA, so as to instruct the calculation means (MC), after expiry of the calculation delay, to det
