Abstract

Upon receipt of an intercepted first Ethernet Frame, a communication system converts the first Ethernet Frame into a second Ethernet Frame including a second identifier based on the first identifier and the conversion information, and sends the second Ethernet Frame toward a first input/output port identified by the second identifier. The system, in sending an Ethernet Frame on which communication service has been executed from the virtual machine, converts the Ethernet Frame on which the communication service has been executed into a third Ethernet Frame including a third identifier identifying a second input/output port of the virtual machine which has executed the communication service. The system converts the third Ethernet Frame into the first Ethernet Frame including the first identifier based on the third identifier and the conversion information and sends the first Ethernet Frame toward the destination of the first Ethernet Frame.
