Latest Patents

Lissianoi’s listed patents focus on improving network operations and handling IPv6 traffic.

- **Mechanism for efficiently transmitting tunnel keep-alive messages.** This invention describes a method for a control processor in a multiprocessor network switching device to trigger forwarding engines to generate and transmit keep-alive packets across the tunnels they service. The approach assigns packet generation to the forwarding engines, supporting efficient tunnel maintenance.

- **Routed split multilink trunking for IPv6.** This invention describes interconnected aggregation devices that exchange MAC-address information and synchronize IPv6 addresses. When either device receives an IPv6 packet destined for the other, it performs a route lookup and forwards the packet to the appropriate next hop.
