NETWORK INTERFACE SWITCHING METHOD, ITS SYSTEM AND ITS RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To realize reduction in overhead for communication restart by excluding the necessity of terminating communication and an application program in the case of switching a network interface independently of a specific communication program and eliminating the need for resetting of the communication by the communication program and restart of the application program. SOLUTION: The communication is made to holding in response to a network interface switching request from an application program AP. Then a 1st network interface NI1 is disabled. After the connection to the application program AP is switched from the 1st network interface NI1 into a 2nd network interface NI2, the 2nd network interface NI2 is enabled, and after the 2nd network interface NI2 is enabled, the holding of the communication is released.
