NETWORK PROTOCOL CONTROLLER AND NETWORK PROTOCOL CONTROLLING METHOD, AND RECORDED MEDIUM ON WHICH NETWORK PROTOCOL CONTROLLING PROGRAM IS RECORDED

摘要

For the operating environment of each application, a service group attribute for uniquely specifying the application is determined, and an IP address uniquely associated with the service group attribute is selected according to the service group attribute. In such a way, an application is uniquely associated with an IP address used by the application, and therefore the degradation of security strength due to addition of the IP address is prevented.
