Latest Patents

One of his latest patents is titled "High throughput layer 2 extension leveraging CPU flow affinity." This patent discloses techniques that leverage CPU flow affinity to increase the throughput of a layer 2 (L2) extension network. In this embodiment, an L2 concentrator appliance bridges a local area network (LAN) and a wide area network (WAN) in a stretched network. It is configured so that multiple Internet Protocol Security (IPsec) tunnels are pinned to respective CPUs or cores, each processing traffic flows for one of the IPsec tunnels. This parallelism can significantly enhance the throughput of the stretched network. Additionally, the L2 concentrator appliance is designed to distribute received FOU packets across receive queues based on a deeper inspection of the inner headers of such packets.

Another significant patent is "Source network address translation detection and dynamic tunnel creation." This approach focuses on detecting source network address translation in internet protocol (IP) tunneling flows. It utilizes learned source IP addresses and source ports to create new tunnels. In this embodiment, a NAT detection application determines whether source IP addresses and source ports associated with new traffic flows match those of a previously configured FOU tunnel. If there is no match, it indicates source network address translation, prompting the NAT detection application to create a new FOU tunnel toward the detected source IP address and source port. The application also authenticates the remote endpoint of the newly created FOU tunnel.
