SDN-WISE: Basic concepts § Directly derived by OpenFlow § Separation between
§ data plane (executed by sensor nodes) § control plane (executed by the Controller)
§ When an event (e.g., the arrival of
a packet) occurs sensor nodes behave as specified in the WISE Table
§ If
there is no relevant information in the WISE Table à Ask the Controller
§ The Controller replies sending a new entry for the WISE Table § A simple protocol defined to allow nodes to:
§ Learn the shortest path towards the (closest) sink(s) § Discover the neighboring nodes § Periodically report local information to the Controller (through the sink)
