The embodiments simplify the development of applications for current and future wireless communication devices, resolving the deficiencies of current methods by providing a hierarchical routing layer which abstracts the actual proximity of the network connection. An application can request and receive a type of network connection without having to address details of the actual connection established. A hierarchical routing layer is provided within the software architecture of each processor within the computing device. The hierarchical routing layer abstracts the actual proximity of the network connectivity on the modem from the applications using proxy network interfaces. The hierarchical routing layers on each processor cooperate to identify a best network interface for an application network request. The routing layer enables response to an application request for a network interface in a simple manner regardless of whether the network interface is provided on the application host processor or another processor.
