1. A method for routing data to a physical communication network interface comprising: receiving a request to transmit data from an application executing a programmatic thread on a computing device having a plurality of physical communication network interfaces for transmitting the data over different communication networks, wherein the request is received at a network layer of the computing device that supports explicit socket bindings to specific physical communication network interfaces; monitoring the request at one or more layered protocol drivers implemented by the networking layer for an explicit socket binding to a specific physical communication network interface; upon determining that the request is without an explicit socket binding to a specific physical communication network interface, identifying a computational context that is associated with the data and relevant for subsequent network operations based on the executing programmatic thread; registering the computational context with a routing interface of the network layer exposed by the one or more layered protocol drivers, the computational context registered by the programmatic thread using a thread identification parameter of the programmatic thread; associating the computational context registered by the programmatic thread with a particular physical communication network interface in a mapping table of the routing interface; receiving the data to transmit from the programmatic thread; and routing the data to the particular physical communication network interface of the computing device for transmission over a communication network based upon the computational context registered by the programmatic thread with the routing interface.
