Latest Patents

One of his latest patents is titled "Counting packet loss in sequence recovery method." This innovative method is executed by a node in a time-sensitive network configured to transmit and receive packets. The method includes providing a state variable, which has a first state in which a packet loss counter is disabled, and a second state in which the packet loss counter is enabled. The packet loss counter can only be incremented to count lost packets when the loss state variable is in the second state. This method enhances the IEEE 802.1CB standard.

Another significant patent is the "Method and system for effective use of internal and external memory for packet buffering within a network device." This mechanism maximizes the utilization of internal memory for packet queuing in network devices. It provides an effective use of both internal and external memory to achieve high performance, high buffering scalability, and minimizes power utilization. The embodiments initially store packet data received by the network device in queues supported by internal memory. If internal memory utilization crosses a predetermined threshold, a background task performs memory reclamation by determining those queued packets that should be targeted for transfer to external memory. Those selected queued packets are transferred to external memory, and the internal memory is freed. Once the internal memory consumption drops below a threshold, the reclamation task stops.
