Abstract
A communication device includes at least one memory and at least one processor coupled to the at least one memory. The at least one processor is configured to: secure a transmission buffer that is not optionally released by a user application; monitor a storage area in which a specific field in an upper protocol header included in payload data of a frame transmitted from the transmission buffer is written; and release the transmission buffer in a case where a storage value stored in the storage area has not been updated for a certain period of time.
