Recovery of Fiber Networks C/M-Plane via an IoT-Based Narrow-Band Links System Based on LoRa Mesh Platform
Although the LoRa private network has started to be used in various applications due to its characteristics, there are only arrangements for carrier sense time, transmittable time, and post-transmission standby time on the LoRa standard and Radio Law. It is necessary for the user side to independently deal with behaviors related to retransmission of data lost at the time of collision and error correction function. In addition, since it is a relatively new wireless communication method, it can be said that it is almost in a disorderly state without unified guidelines and tacit agreements that have been accumulated in the usual way. This situation is particularly problematic when various services start utilizing LoRa with their own protocols, so a uniformly available LoRa platform is necessary. We demonstrate a field-trial experiment of a low-speed/latency/loss tolerable SDN control/management-plane which can take advantage of the widely available IoT resources and easy-to-create wireless mesh for the timely recovery of the C/M-plane after disaster.
