Abstract
Embodiments for adaptive inline modulation tuning for optical interfaces is described. The inline modulation tuning is provided by optical nodes, where the optical nodes exchange optical modulation information and node ability information between optical devices in a node pair. An optimal modulation scheme for the node pair is selected based on modulation abilities of each node and associated transceiver, as well as a link quality and performance observed for the optical link.
Claims20
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.

A system comprising:
- one or more computer processors;
- and
- a memory containing a program which when executed by the one or more computer processors performs an operation 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.
