Latest Patents
One of Hatono's latest patents is a regulation method and apparatus for ATM cell delay variation. This invention includes a variation regulating buffer for temporarily storing cells, a variation waiting timer for controlling the waiting time from reception of the first cell to the read-out of cells, and a read-out timer for managing intervals at which cells are read from the buffer. Additionally, it features a latest cell preservation memory and a selector for transferring the selected cell to a cell reproduction unit. The invention also incorporates a communication type discriminator that calculates a variation waiting time based on the communication type during the call set-up phase. Furthermore, it includes a dummy cell inserting circuit to manage cell delay times in communications involving sound or moving images.
Another notable patent is a cell loss priority control method for ATM switches. This method detects degradation in traffic characteristics for high and low priority classes, estimates a cell loss probability distribution in a buffer, and obtains a buffer threshold value to maximize total traffic throughput. This innovative approach enhances the performance of ATM switches by effectively managing cell loss.
