Latest Patents

One of her latest patents is titled "Traffic multiplexing using timestamping." This invention addresses the challenge of processing multiplexed traffic in systems where the maximum rate of all inputs exceeds the maximum rate of the output. It utilizes a separate queue for each input, ensuring that the earliest enqueued packet is forwarded during each forwarding clock cycle. In cases of congestion, packets are dropped proportionally from each queue based on the number of packets enqueued. This method enhances the efficiency of data transmission by associating a timestamp with each packet.

Another notable patent is "Queue scheduling with priority and weight sharing." This invention introduces a Balanced Packet Transmit Opportunity (BPTO) mechanism that allows balanced bandwidth traffic to be serviced while maintaining the desired service levels for high-priority traffic. The selection process is designed to be fast and simple, enabling the integration of numerous queues into the decision-making process while ensuring a desired output bandwidth. This flexibility allows for modifications to traffic shaping considerations during operations, adapting to changing network requirements.
