Abstract
A communication apparatus comprises a rollback control unit to create a second process to roll back a currently working first process thereto; a storage to store states shared by the first and the second processes, the second process taking over a state(s) stored in the storage unit; a buffer; and a timing control unit that controls of timing of rollback. The rollback control unit starts event buffering to store in the buffer all of an event(s) received during when the first process is processing and destined to the first process, and upon completion of the processing of the event by the first process, the rollback control unit performs switching of a working process from the first process to the second process, sends the event(s) stored therein from start of the event buffering to the second process and stop event buffering.
