1. A method comprising:
exchanging, in an optical based network, optical modulation information and node ability information between a first node and a second node;
selecting the first node as a primary node and the second node as a secondary node based on the node ability information;
monitoring, at the primary node, a link quality for a link between the primary and secondary nodes; and
when the link quality is below a threshold, updating a modulation scheme for the primary and secondary nodes.
