摘要： A wireless peer-to-peer protocol that supports fast and low power joining to an existing group. The protocol may be an extension of a peer-to-peer protocol that supports a sleep state for a device controlling the group. When a device is seeking to join a group at a time when the controlling device is in a sleep state, another device that has information about the controlling device may provide information to the joining device that may then be used by the joining device to more quickly, and using less power, synchronize with the controlling device. The information may include information about a channel used by the controlling device or about timing of availability of the controlling device. The information may also reveal whether the group provides a service being sought by the joining device or may otherwise influence whether the joining device will attempt to join a group.

摘要： Wireless devices that support bootstrapping of a peer-to-peer connection. The wireless devices may use an infrastructure mode connection to exchange security information, such as a PIN, used in establishing the peer-to-peer connection. This security information may be encrypted in accordance with a security protocol used by the access point and then may be applied in a security protocol used to establish a peer-to-peer connection. Such a bootstrapping capability supports operating scenarios in which devices that are communicating over an infrastructure network encounter an operation that requires transfer of large amounts of data and automatically transition to a peer-to-peer connection that provides better performance. With these techniques, a computing device may automatically connect to a display device and stream audio/video data to the display.
摘要翻译：支持对等连接引导的无线设备。无线设备可以使用基础设施模式连接来交换用于建立对等连接的安全信息，例如PIN。该安全信息可以根据接入点使用的安全协议进行加密，然后可以应用于用于建立对等连接的安全协议中。这样的引导能力支持操作场景，其中通过基础设施网络进行通信的设备遇到需要传输大量数据并自动转换到提供更好性能的对等连接的操作。利用这些技术，计算设备可以自动连接到显示设备并且将音频/视频数据流传输到显示器。

摘要： A system in which wireless devices form a group in accordance with a peer-to-peer protocol and, at a later time, a device may send an invitation request to trigger the devices tore-form the peer-to-peer group. The invitation request may contain an identifier that is associated with a set of a plurality of devices. Those devices may be related such that they perform a function for which a user would want to use those devices together. The group of devices, for example, may be multimedia devices that receive and present streaming multimedia content or may be human interface devices that collectively act as an interface for a work station incorporating a wireless computing device operated by a user. Requesting that remote devices concurrently re-form a group reduces the time and spectral congestion associated with re-forming the group, particularly when the remote devices may periodically enter a low power state.
摘要翻译：一种其中无线设备根据对等协议形成组的系统，并且在稍后的时间，设备可以发送邀请请求以触发设备来形成对等组。邀请请求可以包含与一组多个设备相关联的标识符。这些设备可能相关，使得它们执行用户希望将这些设备一起使用的功能。该组设备例如可以是接收和呈现流式多媒体内容的多媒体设备，或者可以是集成地作为包含由用户操作的无线计算设备的工作站的接口的人机接口设备。请求远程设备同时重新组合可以减少与重新组建组相关联的时间和频谱拥塞，特别是当远程设备可能周期性地进入低功率状态时。

摘要： A computing device that forms a group in accordance with a peer-to-peer protocol in which a device may be identified based on a credential of a user. The credential may be used to determine a unique identifier for the user such that the same identifier is used on any device operated by the same user. Such an identifier may be used in connection with a peer-to-peer protocol that supports persistent peer-to-peer groups. As a result, the unique identifier for the user may be retained by remote devices that have paired with any device operated by a particular user such that those remote devices may automatically establish a connection with any other device operated by the same user that similarly uses the same unique identifier for the user.
摘要翻译：根据对等协议形成组的计算设备，其中可以基于用户的凭证来识别设备。凭证可用于确定用户的唯一标识符，使得在由同一用户操作的任何设备上使用相同的标识符。这样的标识符可以与支持持久性对等体组的对等协议相关联使用。因此，用户的唯一标识符可以由与特定用户操作的任何设备配对的远程设备保留，使得那些远程设备可以自动建立与同一用户操作的任何其他设备的连接，其类似地使用相同的唯一标识符为用户。

摘要： An architecture for a computing device to enable the computing device to support peer-to-peer communications using a wireless radio also configured for infrastructure-based communication. The architecture includes a driver for the wireless radio that supports ports for communication in accordance with the peer-to-peer protocol. A port may act as a control port through which action frames that control the formation of a peer-to-peer group may be sent and received. One or more other ports may be used for exchanging data with other devices in the group. Each of these ports may be configured in accordance with its role in the group, such that each port may be configured for operation as a group owner or a client. Additionally, after establishing a group, the control port may be used as a side channel for controlling a device in a group associated with another port.

摘要： A wireless device that automatically forms a connection to a remote device in accordance with a peer-to-peer protocol. The remote device may be designated as an auto-connect device for the wireless device such that, when the wireless device determines that it is in the vicinity of the auto-connect device, it can re-form a connection to the remote device based on stored information for re-establishing connections among a persistent group of devices, but without any express user input. When a user requests that the wireless device perform a function that involves interaction with an auto-connect device, that function may be performed with the delay associated with forming a connection. Any of multiple techniques may be employed for identifying devices designated as auto-connect devices and for determining when the wireless device and a remote, auto-connect devices are in close proximity.

摘要： A wireless computer that pairs with a remote audio-video presentation device, such as a television. As a result of the pairing, a communication channel is established for the computer to transmit audio-video content for presentation through that device. Additionally, as part of the pairing, the computer and remote device select a side channel for communication of user commands. The wireless computer may display a user interface through which a user may input commands that control the manner in which the remote audio-video device presents the content. As a result, a user may use the wireless computer as a remote control for the audio-video device, controlling both the content presented and the manner in which it is presented. The side channel may use different frequencies than the channel used to communicate audio-video content, and may use very low power at frequencies in the digital TV spectrum.

摘要： Techniques for detecting presence of a remote device at Layer 2 in response to an indication of an attempt to use the device and without maintaining a Layer 3 connection to the device. The techniques allow reducing power consumption without compromising the device's availability. A device that pairs with a remote wireless device may establish a Layer 3 connection to the remote device to provide services to a user. The Layer 3 connection and underlying Layer 2 connection (e.g., WI-FI, WI-FI DIRECT™ or BLUETOOTH®) may be terminated when the Layer 3 connection is not actively used. Once use of the remote device is desired, its presence may be detected using a Layer 2 device discovery mechanism and the Layer 2 and Layer 3 connections to the device may be reestablished. Services provided at Layer 3, such as steaming data, may then be performed over the reestablished Layer 3 connection.

摘要： A wireless computing device operating as a controller of a peer-to-peer group configured to generate unique master keys for each device joining the group. The wireless computing device may use the unique master keys to selectively remove remote devices from the group such that the remote device cannot later rejoin the group. Other remote devices, each possessing a master key that remains valid, can disconnect from the group and later reconnect to the group without express user action. To support such behavior, the wireless device may provide a user interface through which a user may manage connected remote devices by providing commands to selectively disconnect or remove remote devices from the group.
