ABSTRACT:
In a switching network through which a path between a source terminal and each of destination terminals is formed, a set of destination addresses is generated at the source terminal, and each of the destination addresses is transmitted from the source terminal to a destination switch node accommodating the destination terminal. Each switch node on the path receives a first set of destination addresses from a previous switch node or the source terminal, and decides whether each destination address of the first set is accommodated in the switch node. Based on the decision, the switch node divides the first set into a plurality of second sets each corresponding to one route of the switch node. Each second set is transmitted to the next switch node through a corresponding route. The next switch node performs the same steps as the switch node mentioned above.
