Abstract: 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.

Abstract: 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.
