Abstract: Techniques are described for an unbuffered multicast delivery mode representing the capability of transmitting a multicast frame within a same DTIM interval during which the multicast frame is received. In an example, a network access device determines that a first computing device is in a power saving mode. The network access device receives, during a DTIM interval while the first computing device is in the power saving mode, a multicast frame destined to a multicast MAC address. The network access device determines an association between the multicast MAC address and a device MAC address of a second computing device. The network access device sends, during the DTIM interval and based on the association, the multicast frame to the second computing device.
