Latest Patents
Yasuda's latest patents include a relay device and relay system. The relay device features a plurality of management cards, including an active card and a standby card. The active card determines whether to open or block a ring port based on events from a ring protocol. It issues instructions to a line card and notifies a block factor when issuing a block instruction. The line card then controls the ring port's status according to these instructions and retains relevant information in a port management table. When the standby card becomes the active card, it acquires the retained information from the line card.
Another notable patent is related to a switching device. In this invention, the encapsulation address of a first switching device is set to differ only in a mask bit compared to a second switching device. A learning information control unit in a third switching device does not learn the correspondence between a source customer address and a source encapsulation address in two specific cases. These cases involve receiving an encapsulated frame at an upper-link port and acquiring an encapsulation address from an address table.
