Abstract
A communication pathway or tunnel can be established between a service node (or other similar node) of a wireless network and an external network using software-defined networking. Packet-based communications can be routed through the wireless network using the communication pathway without requiring a specific node, such as a gateway node, for interfacing with the external network. The software-defined networking system can include program code executed by a computing device to monitor communications in the wireless network and identify a communication that includes a request to establish a communication pathway to the external network. In response, the program code can reprogram network hardware-devices to establish the communication pathway and allow packet communications to be exchanged between the wireless network and the external network via the communication pathway.
