Abstract

A table management unit (114) generates a sub-routing table on the basis of a configuration file which is set by a user and in which a record including an address, the identifier of a communication adapter, the identifier of a routing table, and a table priority is registered, and updates a rule table. On the basis of the rule table, a communication unit (115) selects a routing table having the highest table priority from among routing tables in which use conditions are satisfied among a plurality of routing tables, and communicates with a communication partner using a communication adapter specified on the basis of the selected routing table among a plurality of communication adapters.
