Abstract:
An electronic device includes a port binding module that binds ports to processes. A process running on the electronic device sends a port request to the port binding module. The port binding module determines whether the requested port is a restricted port. If not, the port binding module binds the requested port to the process. If the requested port is restricted, then the port binding module determines whether the requesting process has an entitlement corresponding to the port. If the requesting process has the corresponding entitlement, then the port binding module binds the requested restricted port to the process. If not, then the port binding module denies binding the requested restricted port to the process.
Abstract:
Adapting communication of information based on link-performance characteristics is discussed herein. For the example, an apparatus can include an interface circuit and a processor. The interface circuit communicates with an electronic device via a link. And the processor is communicatively coupled to the interface circuit. The interface circuit provides one or more performance metrics characterizing the link to the processor. And the processor adapts a communication with the electronic device via the link based on the one or more performance metrics.
Abstract:
In order to reduce latency associated with an application executed by an electronic device, when the application transitions from a runnable mode to a suspended state, the electronic device may receive a request from the application to maintain a connection, which is used by the application to communicate with another electronic device, while the application is in the suspended state. Then, the electronic device may provide an instruction to an interface circuit in the electronic device to maintain the connection for a time interval while the application is in the suspended state. This time interval may exceed a predefined timeout for the connection and/or a task extension time for the application. Moreover, prior to providing the instruction, the electronic device may confirm one or more system safeguards to prevent abuse and to ensure system performance and battery life is not adversely affected by maintaining the connection.

Abstract:
The disclosed embodiments relate to a system for selecting an interface for routing an outbound packet. During operation, the system receives an outbound packet to be routed to a destination address. Next, the system obtains application-layer data associated with the outbound packet, including one or more of a process identifier, an application identifier and a user identifier. The system then selects an interface through which to route the outbound packet based on the application-layer data, and uses the selected interface to route the outbound packet.

Abstract:
Techniques are disclosed relating to communicating, via IPv6-only networks, with devices on IPv4 networks. In some embodiments, a mobile device stores program instructions executable to: generate a request to access a network server that specifies an IPv4 literal, query a DNS server using a reserved name to determine an IPv6 prefix, synthesize an IPv6 address using the prefix and the IPv4 literal, create a transport layer connection to the network server using the synthesized IPv6 address, and transmit multiple packets using the connection, without re-translating the IPv4 literal for the packets. These per-connection translation techniques may reduce power consumption and/or processing time relative to per-packet translation, in some embodiments.
