Mellanox Assigned Patent

Mellanox Technologies TLV Ltd., Raanana, Israel, has been assigned a patent (10,015,112) developed by Roitshtein, Amir, Holon, Israel, Aibester, Niv, Herzliya, Israel, Gafni, Barak, Kfar Malal, Israel, and Elias, George, Tel Aviv, Israel, for a “memory-efficient handling of multicast traffic.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Communication apparatus includes multiple interfaces connected to a packet data network. A memory is coupled to the interfaces and configured as a buffer to contain packets received through ingress interfaces while awaiting transmission to the network via respective egress interfaces. Packet processing logic is configured, upon receipt of a multicast packet through an ingress interface, to identify a number of the egress interfaces through which respective copies of the multicast packet are to be transmitted, to allocate a space in the buffer for storage of a single copy of the multicast packet, to replicate and transmit multiple copies of the stored copy of the multicast packet through the egress interfaces, to maintain a count of the replicated copies that have been transmitted, and when the count reaches the identified number, to release the allocated space in the buffer.”

The patent application was filed on December 8, 2015 (14/961,923).
