Method of transactional simulation of a generic communication node model, and the corresponding computer program product and storage means

Computer program product recorded on a non-transitory medium that can be read by computer, said computer program product comprising program code instructions for execution, when said program is executed on a computer, of a method for transactional simulation of a generic communication node model included in a complex system model, said generic node model managing transactions between constituents of said complex system model, wherein said method comprises the following steps, performed at each simulation step corresponding to an event belonging to a group of events comprising transaction starts and transactions ends:

• calculating a remaining quantity of data to be transmitted for each uncompleted transaction present in a list of current transactions;
• if said simulation step corresponds to the start of a new transaction, calculating a quantity of data to be transmitted for the new transaction and adding the new transaction to the list of current transactions;
• if said simulation step corresponds to the end of a transaction, removing the transaction from the list of current transactions;
• allocating throughputs to the current transactions of the list of current transactions, according to a predetermined policy of sharing the generic node model;
• calculating a the smallest duration TpsRk among durations each up to the end time of one of the current transactions:
• TpsRk=MIN(TpsRi), with TpsRi=Qri/Di, TpsRi being the duration up to the time of end of a the current transaction i of the list of current transactions, Qri the quantity of data remaining for the transaction i and Di the throughput allocated to the current transaction i;
• assigning a wait for said duration TpsRk before the generation of the next end of transaction event.

A non-transitory storage medium able to be read by a computer, storing a set of instructions executable by said computer in order to implement a method for transactional simulation of a generic communication node model included in a complex system model, said generic node model managing transactions between constituents of said complex system model, wherein said method comprises the following steps, performed at each simulation step corresponding to an event belonging to a group of events comprising transaction starts and transactions ends:
