Multicast is the transmission of data or network information from a single source device to multiple destinations. One of the most common applications of multicast is streaming video. UPnP, or Universal Plug and Play, is a technology that allows routers to recognise and support connected network devices without any manual set-up. The Netgear WNDR3300 wireless router supports both multicast and UPnP, which can be set up in the router configuration menu.
