Abstract: A communication device includes a transfer control unit and a function execution module having a physical processor. The communication device migrates a first process execution unit operated by the function execution module and a management memory to a function execution module of a migration destination. The function execution module notifies the function execution module of the migration destination of information to specify a program allocated to a second process execution unit and information regarding allocation of the physical processor. The function execution module of the migration destination downloads a program file to start the second process execution unit, operates a program of a new second process execution unit by the function execution module of the migration destination, discards the temporary data on the memory of the second process execution unit, and migrates the second process execution unit to the function execution module of the migration destination.
