Latest Patents

Among his latest patents, two stand out for their ingenuity:

1. **Service Insertion for Multicast Traffic at Boundary**

This invention introduces novel methods for providing transparent services for multicast data messages that traverse a network edge device situated at the boundary of two networks. The approach intelligently analyzes incoming data messages to determine if they need a boundary service and if they are unicast or multicast (including broadcast). It modifies the multicast destination MAC address to a unicast destination MAC address for those requiring services, allowing for direct processing by service nodes without going through standard routing functions. Once the serviced data message is received, it restores the original multicast MAC address before forwarding it to the appropriate destinations.

2. **Scalable Overlay Multicast Routing in Multi-Tier Edge Gateways**

This method addresses the issue of multicast replication by offloading the process from multiple tiers of edge nodes, implemented by various host machines, to a physical switch. The innovation involves a host machine receiving a packet with an overlay multicast group identifier, mapping it to an underlay multicast group identifier, and creating an encapsulated packet. The physical switch then forwards copies of this packet to tenant edge nodes at specified ports, ensuring that only interested nodes receive the replicated multicast traffic.
