1. A network interface module for coupling a host device to a switched network as a network node, the network interface module comprising:
a first external interface including a single half-duplex port for communicatively coupling to a shared bus of a switched network;
a second external interface for communicative coupling to a host device;
at least one frame queue sized to store one multicast read frame received via the shared bus and sized to store one multicast write frame; and
logic circuitry configured to:
decode a read command for the interface module included in a payload of the multicast read frame that includes multiple read commands for other network nodes of the switched network;
transmit a response frame including read data on the shared bus when detecting the shared bus is available for transmitting; and
extract write data from a specified portion of the multicast write frame that includes multiple portions containing write data for other network nodes of the switched network and send the extracted write data to the host device.
