A gateway device is configured to operate as a network function in a service function chain and is connected to a plurality of network connected devices. The gateway device receives a service function chain packet that includes a request to obtain data from one or more of the plurality of network connected devices. The gateway device obtains the data from the one or more network connected devices and modifies the service function chain packet to include the data obtained from the one or more network connected devices. The gateway device sends the service function chain packet that has been modified to include that data obtained from the one or more network connected devices along the service function chain.
