Communication interface apparatus, computer-readable recording medium for recording communication interface program, and virtual network constructing method

A computer-readable recording medium having stored therein a program for causing a communication interface apparatus provided at a first information processing apparatus to perform a process of controlling a communication, the process comprising:

• obtaining setting information from a second information processing apparatus that is different from the first information processing apparatus, the setting information including a piece of virtual network identification information corresponding to a virtual network to which the first information processing apparatus belongs from among pieces of virtual network identification information for identifying virtual networks;
• setting up the virtual network identification information according to the obtained setting information;
• receiving data from a communication network;
• applying a filtering process to the received data according to the virtual network identification information that has been set up;
• and
• transferring to the first information processing apparatus the data to which the filtering process has been applied.

A virtual network constructing method for constructing a virtual network of a cloud computing system that includes a first information processing apparatus that is an information processing apparatus, and a second information processing apparatus that is an information processing apparatus different from the first information processing apparatus, the virtual network constructing method comprising:

• transmitting, to the first information processing apparatus, setting information that includes apiece of virtual network identification information corresponding to a virtual network to which the first information processing apparatus belongs from among pieces of virtual network identification information for identifying virtual networks by using the second information processing apparatus,
• obtaining the setting information transmitted from the second information processing apparatus by using a communication interface provided at the first information processing apparatus,
• setting up the virtual network identification information according to the obtained setting information by using the communication interface,
• receiving data from a communication network by using the communication interface,
• applying a filtering process to the received data according to the virtual network identification information that has been setup by using the communication interface, and transferring to the first information processing apparatus the data to which the filtering process has been applied by using the communication interface.
