Latest Patents
Nagata's latest patents include an input line interface device and a packet communication device. The input line interface device is designed to efficiently accommodate packets from a high-speed line while reducing the processing load on the backend caused by routing control. This device features a packet allotting section that divides variable-length packets, allots them to parallel lines, and outputs the packets. Additionally, a flow group classifying section classifies the packets into flow groups on each of the parallel lines. A sequence number giving section assigns sequence numbers to the packets, which can be either corresponding to or independent of the flow groups. The buffering section stores the packets with assigned sequence numbers in a buffer and manages their retrieval to maintain sequence control. Finally, a flow separating switch separates the packets according to the flow groups for output.
The packet communication device allows packets input from hardware to be organized into time slots A through D. This device alternately switches the input packets in units of time slots and directs them to two 4×4 switches. These switches perform normal switching and distribute the packets to their respective output ports. The packets output from the two 4×4 switches are then alternately multiplexed and sent to the output hardware. This method of switching in packet units prevents increased process overhead and allows for easy expansion while minimizing hardware scale.
