Latest Patents

One of his latest patents is a frame transmission system. This system includes a frame transmitter and a frame receiver. The frame transmitter features a frame fragmentation unit and a reproduction header appending unit. The frame fragmentation unit is designed to fragment an input frame and output transfer frames when the length of the input frame exceeds a predetermined fragmentation reference frame length. Conversely, it does not fragment the input frame and outputs it as a transfer frame when the length is less than or equal to the fragmentation reference frame length. The reproduction header appending unit appends a reproduction header to the transfer frames outputted from the frame fragmentation unit. This header is essential for reproducing the transfer frames at the receiving side, and its length varies according to the input frame's length.

Another significant patent is a bandwidth management apparatus. This apparatus outputs packets by observing the bandwidth set value predetermined for each destination. It includes provisions to prevent situations where the contracted bandwidth cannot be provided due to influences from packets destined for other destinations. When performing bandwidth management using token buckets, each token bucket is updated by setting the upper limit token value higher when any packet is stored in the corresponding queue. This mechanism prevents scenarios where packets cannot be output due to other packets being processed, thus avoiding the discarding of unconsumed tokens.
