latency induced in the exchanges of simulation data the nodes possess only a single network interface via which the real time simulation data and the non real time diagnostic data pass in addition during the configuration phase the igmp protocol acronym for u201c internet group management protocol u201d in english terminology is used to configure the redirection table of the switch making possible management of multicast ip addresses in addition the electronic interface nodes of the network must respect the emission windows in order to emit the responses and the dispatches of messages in asynchronous mode finally emission of data in unicast mode must be given preference there now is described an algorithm that uses the emission window for diagnostic data this algorithm is executed by the diagnostic task of the client nodes each simulation data message is characterized by a pair comprising an identifier id and a time period t in milliseconds as well as by an application data format predefined beforehand for any simulation a sequencing table comprising a set of pairs having an identifier and a time period is furnished by the simulation terminal to each node of the network during the configuration phase thus each node of the network possesses a specific sequencing table starting from this table each client node must then work by time based.
