Abstract
Upon sensing an update of any routing information entry held in a routing information storage unit (A), an information exchange coordination unit (A) references a node information storage unit (A), and if a node information entry corresponding to the updated routing information entry does not exist, acquires the corresponding node information entry from another communication terminal (A). Alternatively, upon sensing an update of any node information entry held in the node information storage unit (A), the information exchange coordination unit (A) references the routing information storage unit (A), and if a routing information entry corresponding to the updated node information entry does not exist, acquires the corresponding routing information entry from another communication terminal (A). This provides a communication terminal for acquiring both the node information entry and the routing information entry relating to a specific communication terminal substantially at the same time.
