Node, computer-readable medium storing communication program, and communication method

A first node that executes primary communication and secondary communication via a network between a first node group and a second node group, the first node group including the first node and a second node, the second node group including a third node and a fourth node, the first node comprising:

• a memory;
• and
• a processor coupled to the memory and configured to execute a process, the process including:
• receiving, from the second node, data related to the secondary communication conducted between the second node and the fourth node,
• setting a communication path via the network between the first node and the third node,
• computing, based on transmission capabilities of the network, a required time to transmit data that has been designated as outgoing data from a start time of a periodically executed transmission process with regard to the primary communication up until a current time, wherein the designated data is data from among the received data that has been successively designated as outgoing data,
• determining whether a time equal to the current time plus the required time matches the start time of the primary communication periodically conducted between the second node and the fourth node, and
• deciding which data from among the received data to designate as outgoing data based on the determining,
• the data related to the secondary communication differs from data being sent by the primary communication.

A node on a network in which a plurality of node groups are connected via at least one junction apparatus, the node comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• take data successively designated as outgoing data from among a data group, and transmit the data to a node selected from the node group from among the plurality of node groups that contains a current node,
• compute, based on transmission capabilities of the network, a required time to transmit a data sequence that has been successively designated as outgoing data from a start time of a periodically executed transmission process up until a current time,
• determine whether a time equal to the current time plus the required time matches the start time of a periodically executed communication process between nodes in any of the plurality of node groups, and
• designate data from among the data group as outgoing data based on a relationship between the time equal to the current time plus the required time and the start time,
• the data from among the data group differs from data being sent by the periodically executed communication process.

A computer-readable, non-transitory medium storing therein a communication program that causes a computer of a first node to execute a process, the computer of the first node executing primary communication and secondary communication via a network between a first node group and a second node group, the first node group including the first node and a second node, the second node group including a third node and a fourth node, the process comprising:

• receiving, from the second node, data related to the secondary communication conducted between the second node and the fourth node;
• setting a communication path via the network between the first node and the third node;
• computing, based on transmission capabilities of the network, a required time to transmit data that has been designated as outgoing data from a start time of a periodically executed transmission process with regard to the primary communication up until a current time, wherein the designated data is data from among the received data that has been successively designated as outgoing data;

• and
• deciding which data from among the received data to designate as outgoing data based on the determining,
• the data designated from among the received data by the deciding differs from data being sent by the primary communication.

A communication method whereby a computer of a first node executes primary communication and secondary communication via a network between a first node group and a second node group, the first node group including the first node and a second node, the second node group including a third node and a fourth node, the communication method comprising:
