Provided are a node unit comprising a queuing engine for multicasting Ethernet data, and a distributed antenna system comprising the same. The node unit is a node unit which is branch-connected to a plurality of sub-nodes, and comprises: a media access control (MAC) module; and a queuing engine for interfacing Ethernet data between the MAC module and the plurality of branch-connected sub-nodes, wherein the queuing engine comprises a buffer for multicasting Ethernet data received from the MAC module to the plurality of branch-connected sub-nodes, transferring Ethernet data received from the plurality of branch-connected sub-nodes to the MAC module, buffering Ethernet data received from the plurality of branch-connected sub-nodes, and outputting the buffered Ethernet data to the MAC module. |
