Abstract: A network element includes a plurality of ports, multiple computational modules, configurable forwarding circuitry and a central block. The ports include child ports coupled to child network elements or network nodes and parent ports coupled to parent network elements. The computational modules collectively perform a data reduction operation of a data reduction protocol. The forwarding circuitry interconnects among ports and computational modules. The central block receives a request indicative of child ports, a parent port, and computational modules required for performing reduction operations on data received via the child ports, for producing reduced data destined to the parent port, to derive from the request a topology that interconnects among the child ports, parent port and computational modules for performing the data reduction operations and to forward the reduced data for transmission to the selected parent port, and to configure the forwarding circuitry to apply the topology.

Abstract: Communication apparatus includes a plurality of interfaces for receiving and transmitting data packets from and to a network and a memory, which receives and stores context data with respect to multicast groups. Packet processing circuitry establishes reliable connections over the network with the receiving nodes in the multicast groups, and upon receiving from a packet source on the network an incoming unicast packet containing multicast data and containing multicast metadata that identifies a multicast group, sends an acknowledgment of the incoming unicast packet to the packet source, reads the context data from the memory with respect to the identified multicast group, and transmits multiple outgoing unicast packets containing the multicast data via respective egress interfaces to the receiving nodes in the multicast group over the reliable connections.
