Abstract
Methods of Internet of Things (IoT) device access are disclosed. In one embodiment, a method is implemented in a software-defined networking (SDN) controller. The method includes receiving a node discovery request from a network device that receives a unicast neighbor solicitation message from an electronic device that supports IPv6. The unicast neighbor solicitation message contains an IPv6 address to be registered. The method also includes causing a device entry to be generated in a device discovery table, and transmitting an acknowledgment to the network device upon the device entry being generated successfully. The method continues with transmitting a request to the network device to generate a flow table entry for the electronic device based on a policy table. The flow table entry includes an operation to be performed, and the network device is to perform the operation on a packet received matching the flow table entry.
