Abstract
Techniques are described for optimizing broadcast and collect primitives in switch fabrics. A switch is described for use in a switch fabric that includes a plurality of switches configured to interconnect a plurality of host devices. The switch includes a plurality of ports configured to receive and transmit data, and switch logic configured to facilitate transfer of the data among the ports. The switch logic is configured to implement a collect function in which responses from multiple destination host devices are collected and aggregated for transmission to a source host device. A first portion of the switch logic is configured to identify, count, and discard the responses in a data plane of the switch. A second portion of the switch logic is configured to generate an aggregated response in a control plane of the switch and introduce the aggregated response into the data plane for transmission toward the source host device.
