Patent number: 11218415Abstract: A network element includes multiple ports and forwarding circuitry. The ports are configured to serve as network interfaces for exchanging packets with a communication network. The forwarding circuitry is configured to receive a multicast packet that is to be forwarded via a plurality of the ports over a plurality of paths through the communication network to a plurality of destinations, to identify a path having a highest latency among the multiple paths over which the multicast packet is to be forwarded, to forward the multicast packet to one or more of the paths other than the identified path, using a normal scheduling process having a first forwarding latency, and to forward the multicast packet to at least the identified path, using an accelerated scheduling process having a second forwarding latency, smaller than the first forwarding latency.Type: GrantFiled: November 18, 2018Date of Patent: January 4, 2022Assignee: MELLANOX TECHNOLOGIES TLV LTD.Inventors: Lion Levi, Amiad Marelli, George Elias, Oded Zemer, Yoav Benros

Patent number: 10880236Abstract: Communication apparatus includes multiple ports configured to serve as ingress and egress ports, such that the ingress ports receive packets from a packet data network for forwarding to respective egress ports. The ports include an egress port configured for connection to a network interface controller (NIC) serving multiple physical computing units, which have different, respective destination addresses and are connected to the NIC by different, respective communication channels. Control and queuing logic is configured to queue the packets that are received from the packet data network for forwarding to the multiple physical computing units in different, respective queues according to the destination addresses, and to arbitrate among the queues so as to convey the packets from the queues via the same egress port to the NIC, for distribution to the multiple physical computing units over the respective communication channels.Type: GrantFiled: October 18, 2018Date of Patent: December 29, 2020Assignee: MELLANOX TECHNOLOGIES TLV LTD.Inventors: Lion Levi, Eitan Zahavi, Amiad Marelli, George Elias, Liron Mula, Oded Zemer, Sagi Kuks, Barak Gafni, Gal Shohet, Harold Rosenstock

Patent number: 10708219Abstract: A method for communication, includes routing unicast data packets among nodes in a network using respective Layer-3 addresses that are uniquely assigned to each of the nodes. Respective Layer-2 unicast addresses are assigned to the nodes in accordance with an algorithmic mapping of the respective Layer-3 addresses. The unicast data packets are forwarded within subnets of the network using the assigned Layer-2 addresses.Type: GrantFiled: November 20, 2016Date of Patent: July 7, 2020Assignee: MELLANOX TECHNOLOGIES, LTD.Inventors: Zachy Haramaty, Diego Crupnicoff, Freddy Gabbay, Benny Koren, Amiad Marelli, Itamar Rabenstein, Ido Bukspan, Oded Zemer

Patent number: 10218642Abstract: A network switch includes circuitry and multiple ports, including multiple input ports and at least one output port, configured to connect to a communication network. The circuitry includes multiple distinct-flow counters, which are each associated with a respective input port and with the output port, and which are configured to estimate respective distinct-flow counts of distinct data flows received via the respective input ports and destined to the output port. The circuitry is configured to store packets that are destined to the output port and were received via the multiple input ports in multiple queues, to determine a transmission schedule for the packets stored in the queues, based on the estimated distinct-flow counts, and to transmit the packets via the output port in accordance with the determined transmission schedule.Type: GrantFiled: March 27, 2017Date of Patent: February 26, 2019Assignee: Mellanox Technologies TLV Ltd.Inventors: Liron Mula, Sagi Kuks, George Elias, Eyal Srebro, Ofir Merdler, Amiad Marelli, Lion Levi, Oded Zemer, Yoav Benros
