<p><P>PROBLEM TO BE SOLVED: To provide a communication environment which keeps communication without using a third node, increases security at that time, and is suitable for each application when a communication interface to be used is switched. <P>SOLUTION: A communication interface switching manager 20 selects the communication interface to be used at each application from among a plurality of communication interfaces and switches it. A virtual interface 41 gains data transmitted from an application portion to a node B and provide an application part with the data transmitted from the node B. An address switching part 42 converts an address of a node A added to data between the address of the communication interface used for every application and a virtual address. Further, an agent 32 provides the node B with common information to verify the node itself to be identical before and after the switching when the switching is conducted. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
