1. A method comprising:
obtaining, by a first data-plane node of a data-traffic path of a software-defined networking (SDN) mesh network, SDN sub-controller permission from a controller of the SDN mesh network, the SDN sub-controller permission including permissions for the first data-plane node to switch among multipaths in flow tables for the SDN mesh network without communicating with the controller;
receiving, at the first data-plane node, a flow table from the controller of the SDN mesh network, the flow table indicating multipath routes to a second data-plane node including a first route from the first data-plane node to the second data-plane node and a second route from the first data-plane node to the second data-plane node;
communicating, by the first data-plane node, with the second data-plane node using the first route;
determining that the first route disconnected between the first and second data-plane nodes;
determining, using the sub-controller permission and without communicating with the controller to receive a new route, to switch from the first route and to the second route; and
using the flow table stored at the first data-plane node,
communicating, by the first data-plane node, with the second data-plane node using the second route.
