Wireless applications in certain domains, e.g., automotive, Internet-of-Things (IoT), etc., consume substantial amounts of bandwidth. A user accustomed to data consumption on a mobile device may be surprised to find the substantially larger amounts of data consumed via telemetry by wireless devices and sensors on their automobile. Reciprocally, a car manufacturer may not want a customer to pay for telemetry. This disclosure describes techniques to route network traffic to specific network interfaces on a per-application basis. The techniques can be implemented in a device operating system, and provide mechanisms for users and original equipment manufacturers (OEMs) to separate data costs for usage of various applications, thereby enabling a robust, secure, and connected experience.
