A low latency multicasting receive and send apparatus and method comprising low latency receive and send queues. In an InfiniBand® network each destination group of nodes (recipients) is identified by a unique Global ID (GID)+Local ID (LID). Each node whose ports are part of a multicast group identify themselves via a LID which identifies participating ports. When a switch receives such a multicast packet with a multicast LID in the packet's DLID field it replicates the packet to each of the designated ports. Each destination adapter at a receiving node receives the multicast packet and distributes copies of the packet to QPs in the host system that are registered for the multicast address.
