摘要： Example techniques related to portable playback device power management. An example implementation involves launching a power coordinator background process, the power coordinator background process having multiple client programs and establishing respective inter-process communication (IPC) mechanisms between the multiple client programs and the power coordinator background process. The implementation further involves receiving, via the established IPC mechanisms from the multiple client programs, messages indicating that the respective client program is ready to suspend, and determining that each client program of the multiple client programs is ready to suspend. The implementation further includes sending instructions to the operating system to kernel suspend. While in kernel suspend, the playback device detects a particular trigger to kernel resume and in response, performs a kernel resume.

摘要： Embodiments are described herein that allow a playback device to transition between operating modes to, among other things, conserve power. In one aspect, a method is provided. The method involves determining that a playback device is operating in one of a powered mode and a battery mode. The powered mode comprises the playback device receiving power from an external source. The battery mode comprises the playback device receiving power from at least one battery. The method further involves causing the playback device to serve as a network bridge when the playback device is in the powered mode. The method further involves causing the playback device to serve as a client device and not serve as a network bridge when the playback device is in the battery mode.

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 and methods for maintaining knowledge of a network address (e.g., a MAC address) for a playback device while changing power states are disclosed. In one embodiment, a method for maintaining knowledge of the network identity of a playback device while changing power states includes determining that a playback device is entering a sleep state, sending state information from the playback device to a central data repository over a network responsive to the determination that the playback device is entering sleep state, where state information includes a MAC address, receiving the state information about the playback device at a waking device from the central data repository, waking the playback device periodically at predetermined time intervals while in sleep state to listen for messages addressed to the MAC address, and receiving a wake-up message at the playback device from the waking device and responding by changing from sleep to active state.

摘要： An example implementation may involve a first playback device accessing, from a file, first network parameters. The first playback device determines that it is unable to establish a valid network connection to the first WLAN using the first network parameters. In response, the first playback device broadcasts a probe request message. The first playback device receives, from a second playback device, a response to the probe request message, the response to the probe request message indicating second network parameters that are assigned to a network interface of the second playback device. The first playback device establishes a valid network connection to the particular WLAN using the second network parameters and joins, via the established network connection to the particular WLAN, a media playback system that comprises the second playback device.
