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.

Roaming groups in a Peer-to-Peer Network

Techniques for connection information for inter-device wireless data communication are described. In at least some embodiments, a broker device maintains wireless connection information for various wireless devices. The wireless connection information includes wireless channels at which particular wireless devices can be accessed. The broker device can provide the wireless connection information to various other devices to enable wireless communication with the wireless devices.

Connection information for inter-device wireless data communication

An overlay network refers to a network that is implemented as various different virtual resources on a physical network referred to as an underlay network. Diagnostics are performed on the overlay network by injecting diagnostic packets from a source endpoint targeting a target endpoint. These endpoints can be in the overlay network, on-premises with the other endpoint but in a different overlay network, or off-premises form the other endpoint. The diagnostic packets include a data packet encapsulated with a diagnostic encapsulation header that can be removed by a network element in the underlay network to allow processing of the data packet, and then added back on. The network element maintains trace information that is a record of receipt of the diagnostic packet and operations performed on the diagnostic packet. A tracing service collects and analyzes this trace information from the various network elements.

Active flow diagnostics for cloud-hosted networks

Technology for managing operational modes of a network adapter is disclosed. The technology includes features for selectively preempting (e.g., canceling, suspending, deferring, pausing, changing to a 'no-op' state, changing to a passive state, or otherwise deprioritizing) execution for a current operational mode of the network adapter, executing a requested network control operation, and optionally restoring the preempted operational mode. The operational mode may be selectively preempted based on priority information associated with the current operational mode and the requested network control operation.

Network mode conflict resolution

Technology for managing queuing resources of a shared network adapter is disclosed. The technology includes selectively transferring data from data transmission sources to a queue of the shared network adapter based on status indications from the shared network adapter regarding availability of queuing resources at the shared network adapter. In addition, the technology also includes features for selectively controlling transfer rates of data to the shared network adapter from applications, virtual network stations, other virtual adapters, or other data transmission sources. As one example, this selective control is based on how efficiently data from these data transmission sources are transmitted from the shared network adapter.

Management of multilevel queues for shared network adapters

Roaming groups in a peer-to-peer network

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.

Peer-to-peer discovery

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.

Auto-connect in a peer-to-peer network

Technology for allocating network adapter resources such as air interface time and queue space amongst multiple virtual network stations or other virtual adapters is disclosed. As one example, the resource allocation may be based on analysis of the relative latency, jitter, or bandwidth considerations for applications communicating via each of the multiple virtual adapters. The resource allocation may also be based on how efficiently each of the virtual adapters utilized previously allocated resources.
