摘要： A method and apparatus for managing simultaneous virtual connections with multiple wireless networks. A plurality of ports in a hardware driver may be each associated with a corresponding wireless network and maintain a unique MAC state relative to other ports. Each port may have a corresponding virtual NIC that communicates directly with the radio hardware via a hardware virtualization layer that multiplexes communication between the virtual NICs and the radio hardware. Simultaneous virtual connections may be made with one or more infrastructure networks or adhoc networks, and/or the computer may function as an access point for one or more of the networks.

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.
摘要翻译：支持快速和低功率加入现有组的无线对等协议。该协议可以是支持用于控制该组的设备的睡眠状态的对等协议的扩展。当设备正在寻求在控制设备处于睡眠状态时加入组时，具有关于控制设备的信息的另一设备可以向加入设备提供信息，然后可以由加入设备更快地使用该信息并且使用较少的功率，与控制设备同步。信息可以包括关于控制设备使用的信道或关于控制设备的可用性的定时的信息。该信息还可以显示该组是否提供正在由加入设备寻求的服务，或者否则会影响加入设备是否将尝试加入组。

摘要： Techniques for monitoring presence of a remote device at Layer 2 that 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, such as an IP connection, to the remote device to provide services to a user. The Layer 3 connection may be formed over a Layer 2 connection via an access point or as a peer-to-peer wireless connection between the devices. When the Layer 3 connection is not actively used to access the remote device, the Layer 3 connection and the supporting Layer 2 connection (e.g., WI-FI, WI-FI DIRECT™ or BLUETOOTH®) may be terminated and presence of the remote device may be monitored using a Layer 2 device discovery mechanism. The Layer 2 and Layer 3 connections to the device may be reestablished when use of the remote device is desired.

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： 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： 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： A wireless device that discovers other wireless devices for the formation of a peer-to-peer connection may perform a scan that is limited in duration and power consumption. The scan nonetheless is highly likely to discover a device, if a discoverable device exists. In addition, the scan may be performed in compliance with parameters of a peer-to-protocol such that the scan may be readily implemented in a wireless device, in some embodiments even as a firmware upgrade on a wireless network interface card. Parameters of the scan may be adjusted to increase the likelihood that, if the scan completes without discovering a device, no discoverable device exists. The scan may be used in an overall process in which discovery ends or the scan is selectively repeated following an unsuccessful scan, without entering a find phase.
摘要翻译：发现用于形成对等连接的其他无线设备的无线设备可以执行在持续时间和功耗方面受到限制的扫描。如果存在可发现的设备，则扫描很有可能发现设备。此外，可以根据对等协议的参数执行扫描，使得扫描可以容易地在无线设备中实现，在一些实施例中，即使在无线网络接口卡上的固件升级。可以调整扫描的参数以增加如果扫描在没有发现设备的情况下完成的可能性，则不存在可发现的设备。扫描可以在发现结束的整个过程中使用，或者在不成功扫描之后选择性地重复扫描，而不进入查找阶段。

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.
