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： 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： 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 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： 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： 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 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.
