摘要： Certain examples identify a device's useful wired connection and, when found, facilitate network configuration according to that useful wired connection. An example method includes periodically transmitting, by a first device, a first message over a wireless network interface. The example method includes listening, by the first device, for the first message over a wired network interface. The example method includes, when the first device at least receives the first message over the wired network interface, transmitting, by the first device to at least one additional device over the wireless network interface, a second message, wherein the second message includes an indication, the indication indicating that the at least one additional device can change its network configuration to utilize the wired network interface of the first device.

摘要： Systems, methods, apparatus, and articles of manufacture to provide root re-selection in a spanning tree protocol are disclosed. An example method includes transmitting, from a current root device on a playback network, a query message to a router on the playback network. The example method includes evaluating a response received from at least one intermediate device between the current root and the router, the at least one intermediate device relaying the query message from the root to the router and transmitting a response back to the current root device indicating a root path cost associated with that intermediate device. The example method includes determining, based on the received root path cost(s), an updated designation of a new root device for the playback network. The example method includes, if the new root device is different from the current root device, exchanging bridge priority between the current root and the new root.

摘要： Systems, methods, apparatus, and articles of manufacture to provide for low-latency delivery and playback of audio are disclosed. In one embodiment, an example audio system includes multiple playback devices including a primary device and one or more secondary devices, whereby, the primary device establishes and controls a peer-to-peer network that connects, wirelessly or wired, to each of the satellite devices. An example audio device contains a channel selector, a control interface, and an audio interface. In some embodiments the control interface is used to transmit control information to another device on a first frequency channel, and the audio interface is used to transmit audio information to another device on a second frequency channel.
