Title: Transfer data base managing device
Inventor: ONODA MINORU
IPC: G06F13/00
Filed: 1990-11-30
Abstract: PURPOSE:To reduce a burden on a microprocessor and to easily perform the update of a transfer data base by deleting information with respect to a node stored previously when no update of entry data is performed within the prescribed update period of a timer value by a shift register. CONSTITUTION:When the information with respect to the node is registered to the transfer data base, a CPU retrieves the transfer data base setting the node address of an area for node address storage as a key first. When an entry with respect to the node address exists, the entry is updated, and a new node address is registered on a null area when no entry exists. Thence, the timer value in the shift register is shifted up based on a clock generated periodically from a clock generator. In such a case, the node address registered first is automatically deleted from the data base when the update of the entry is not performed within a certain specific time. Thereby, it is possible to reduce the burden on the microprocessor, and to easily perform the update of the transfer data base.
