TECHNICAL FIELD

Embodiments presented in this disclosure generally relate to network communication in optically based connected networks. More specifically, embodiments disclosed herein relate to coordinating and updating optical modulation schemes between network nodes in order to optimize or improve network communication between the nodes on the optical network.

BACKGROUND

In packet based optical networks, routers and other optical devices are connected using optical transceivers and fibers between the optical transceivers/devices. The new generation of digital coherent optics (DCO) modules are capable of supporting different and advancing modulation schemes which support higher transmission speeds. However, in current implementations, it is the responsibility of a user/administrator to iteratively configure the modulation schemes at the transceivers/DCO modules on both ends of an optical link and monitor optical performance parameters. The user/administrator must then decide on an optimal speed that is acceptable to the optical network and user needs. These user based methods are in turn difficult to implement effectively, error prone, and slow to adapt as network conditions such as link quality change.
