In a source address selection system containing a router device (R1, R2) connected to a plurality of Internet service providers (ISPa, ISPb, ISPc, ISPd), and a communication node (N) connected to the router device, it becomes possible to utilize the multi-home environment effectively, by enabling the selection of the source address according to the egress router (R1, R2) with respect to the Internet (I), by accounting for the state of connection with the Internet service provider (ISPa, ISPb, ISPc, ISPd).
