METHOD, DEVICE AND STORAGE MEDIUM FOR AN INTERNET OF THINGS (IOT) DEVICE ACCESS IN A SOFTWARE-DEFINED NETWORKING (SDN) SYSTEM

摘要

Methods of Internet of Things (IoT) device access are disclosed. In one embodiment, a method is implemented in a software-defined networking (SDN) controller (150). The method includes receiving a node discovery request from a network device (110) that receives a unicast neighbor solicitation message from an electronic device (122) 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 (152), and transmitting an acknowledgment to the network device (110) 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 (122) based on a policy table (154). The flow table entry includes an operation to be performed, and the network device (110) is to perform the operation on a packet received matching the flow table entry.
