Abstract: A method includes receiving multicast traffic intended for host devices; identifying a flow associated with the multicast traffic; retrieving information associated with a group of multicast trees, where the group of multicast trees includes information associated with a group of I/O units, associated with a network node; identifying a particular tree that corresponds to the identified flow, where the particular tree includes information associated with a set of I/O units; and transferring the multicast traffic to an I/O unit, of the set of I/O units, based on the identification of the particular tree, where the transferring enables the I/O unit to send a copy of the multicast traffic to other I/O units of the set of I/O units, and the set of I/O units to process the multicast traffic in a manner that utilizes bandwidth or processing resources in a controlled manner and to send a copy of the multicast traffic to each of the host devices.
