Abstract: Data is transferred by establishing a communication link without deciding in advance the primary and the secondary nodes in a distributed processing system which uses a connection oriented API. When an application program (AP) issues a connection request signal, a communication link A1 is brought to a condition in which it can be established (S100) and a communication link A2 is brought to a condition in which it can be accepted (S102). It is determined whether or not the communication link has been established (S104). If the link A2 is established, the communication link A2 is registered as a communication link A (S106) while it is requested to establish the communication link A1 otherwise (S108). It is determined whether or not the communication link A1 has been established (S10) and, if it is established, it is registered as a communication link A. Otherwise, it waits for a predetermined time period then repeats establishment of the communication Link A1 or A2 and transfers data on whichever link is established earlier.
