 This networking stack is using standard 6LoWPAN and uses:
 
 * Neighbor Discovery Protocol ([RFC4861](https://tools.ietf.org/html/rfc4861)) to locate other devices in the mesh network. 
 * Mesh-Link-Establishment ([draft-kelsey-intarea-mesh-link-establishment-06](https://tools.ietf.org/html/draft-kelsey-intarea-mesh-link-establishment-06)) is used for establishing and configuring secure radio links.

-Mbed OS release 5.12 contains the initial Mbed Wi-SUN FAN implementation. Functionality of the Mbed Wi-SUN network stack will be updated when the Wi-SUN protocol is specified further.
