Communication apparatus and configuration method

摘要

An information processing unit of a communication apparatus includes a non-volatile memory and a volatile memory. A control unit of the communication apparatus loads the boot image from the non-volatile memory to the volatile memory upon activation of the communication apparatus, activates the virtual machine template in the loaded boot image on the volatile memory, deactivates the activated virtual machine template after reconfiguring the activated virtual machine template to minimum required configuration to execute a virtual machine. Upon receipt of a request for addition of communication service, the control unit creates a replicate virtual machine template by replicating the deactivated virtual machine template, activates the replicate virtual machine template, reconfigures the activated replicate virtual machine template to configuration according to the request for addition of communication service, and executes the reconfigured replicate virtual machine template as a virtual machine to provide the communication service.

主权项

1. A virtual machine processing apparatus connected in a communication path between a server and a client for transmitting Ethernet Frames via a physical network, the virtual machine processing apparatus comprising:
an information processing unit including at least one virtual machine for executing a communication service to the Ethernet Frames; and a control unit for controlling the virtual machine processing apparatus, wherein the information processing unit includes: a first memory for storing a boot image including a primary virtual machine template which is a program for executing a virtual machine; and a second memory used to execute the communication service, wherein the control unit loads the boot image from the first memory to the second memory, wherein the control unit creates a secondary virtual machine template for executing a virtual machine by reconfiguring the primary virtual machine template, wherein the control unit stores the secondary virtual machine template in the second memory, wherein, upon receipt of a request for addition of communication service, the control unit creates a replicate secondary virtual machine template by replicating the second virtual machine template, wherein the control unit creates a virtual machine for the communication service by reconfiguring the replicate secondary virtual machine template in accordance with a request for addition of the communication service, wherein the boot image includes a program to execute a virtual switch, wherein the primary virtual machine template includes a program for executing at least one virtual network interface for connecting with the virtual switch, and wherein the control unit configures the at least one virtual network interface included in the primary virtual machine template to receive the Ethernet Frames when the control unit creates the secondary virtual machine template.
