Abstract: According to an embodiment, a terminal device includes a memory unit, a managing unit, a detecting unit, a reference assigning unit, a reference deleting unit, a determining unit, and a changing unit, and a deleting unit. The detector detects that a first graph element read by a processing unit is updated before the start of transactions being executed by the processing unit. The determining unit determines that a first graph element is updated before the start of the oldest transaction being executed and does not have reference information assigned thereto. The first graph element is pointed to by link information of a second information. The changing unit changes the link information of the second graph element to point to a third graph element, or delete the link information. The deleting unit deletes the first graph element.

Abstract: According to an embodiment, a terminal device includes a memory unit, a managing unit, a manipulation recording unit, and at least one of first and second detecting units. The managing unit generates and deletes a processing unit which executes a transaction for individually manipulating data with respect to data elements and data containers stored in the memory unit.

The first and second detecting units detect the presence or absence of competition. The first detecting unit detects competition during an execution state of a transaction as set by the processing unit. The second detecting unit detects competition during a commit preparation state of a transaction as set by the processing unit. When at least either the first detecting unit or the second detecting unit detects competition, the processing unit aborts the transaction.

Abstract: A packet processor transfers a message received by a first (second) port to a second (first) port. When first specific information is included in the received message, a QoS terminal detector detects a communication terminal, which is a sender of the message received by the first port or a destination of the message received by the second port, as a QoS terminal requesting application of QoS. When the QoS terminal does not satisfy a preset connection condition associated with the QoS terminal connectable to the first port via a first network, an output unit outputs information indicating that the connection condition is not satisfied.
