Abstract:
1. A method comprising: identifying, at a first playback device, a multicast message including a data frame to be directed to a group of playback devices via a network protocol; evaluate a number of outgoing ports of the network interface to identify a number of wired ports and a number of wireless ports; and based on the number of wired ports of the first playback device and an associated state of the wired ports, override the network protocol for the group of playback devices to enable direct routing to transmit a unicast message based on the multicast message via direct routing to each member of the group of playback devices that is a neighbor of the first playback device and maintaining the network protocol to transmit the multicast message via the network protocol to each member of the group of playback devices that is not a neighbor of the first playback device.
