Methods and apparatus for efficient data transfer within a user space network stack. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional 'socket' based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack).

Methods and apparatus for sharing and arbitration of host stack information with user space communication stacks

An event is detected at a first device. Responsive to the detection, at least some functionality of the first device is deactivated. The presence of a second device, cryptographically paired with the first device, is detected by the first device. Responsive to the detection, at least some functionality of the first device is activated or reactivated.

Activation of cryptographically paired device

A navigation system includes a user interface for detecting touch input. The system uses touch input to determine if a driver or passenger is operating the navigation system. If the system determines that the driver is operating the system, then an action is initiated (e.g., the user interface is locked down, a warning is provided). The navigation system allows a passenger in the vehicle to operate the navigation system while the vehicle is in motion. In an aspect, additional or other sensors (e.g., seat sensor, seat belt sensor, infrared sensor) can be used to detect whether a driver or passenger is operating the navigation system while the vehicle is in motion.

Intelligent restriction of device operations

In some implementations, a mobile device can be configured to monitor environmental, system and user events. The occurrence of one or more events can trigger adjustments to system settings. In some implementations, the mobile device can be configured to keep frequently invoked applications up to date based on a forecast of predicted invocations by the user. In some implementations, the mobile device can receive push notifications associated with applications that indicate that new content is available for the applications to download. The mobile device can launch the applications associated with the push notifications in the background and download the new content. In some implementations, before running an application or accessing a network interface, the mobile device can be configured to check energy and data budgets and environmental conditions of the mobile device to preserve a high quality user experience.

Initiating background updates based on user activity

Techniques for electronic devices to control a multipath transmission control protocol (MPTCP) connection. An MPTCP connection between two endpoints may be established. The MPTCP connection may include at least one MPTCP subflow. At least one of the endpoints may be configured to act as a master with respect to the MPTCP connection. The master may perform one or more control operations on the MPTCP connection, while if one of the endpoints is not a master, that endpoint may not perform control operations on the MPTCP connection. The control operations may include initiating or establishing new MPTCP subflows or modifying a priority level of one or more MPTCP subflows of the MPTCP connection.

Multipath TCP subflow establishment and control

Methods for establishing a direct peer-to-peer ('P2P') connection between two computers are disclosed. In particular, the methods are designed to work in cases where one or both of the computers are connected to a private network, such private networks being interconnected via a public network, such as the Internet. The connections between the private network and the public network are facilitated by network address translation ('NAT').

NAT traversal for media conferencing

In some implementations, a network daemon can manage access to a mobile device's network interface. The network daemon (e.g., network connection managing process) can monitor the condition of the mobile device's network connection on one or more interfaces. The network daemon can monitor many conditions on the mobile device. The network daemon can receive background networking requests from network clients (e.g., processes, applications) that specify criteria for initiating a network connection. The network daemon can then smartly manage network connections taking into account network conditions, mobile device conditions and/or client criteria received in the client request. This can help reduce battery life impact, memory usage, likelihood of call drops, data usage cost, and load on network operators.
