1. A method, comprising:
receiving, by an orchestrator of an optical network, an operation to execute, the optical network comprising a fiber optic line and two or more reconfigurable optical add-drop multiplexers (ROADMs), the operation being a loading of a first optical service on the fiber optic line by a local ROADM of the two or more ROADMs;
determining a status of a downstream ROADM of the two or more ROADMs as being available, the downstream ROADM being downstream from the local ROADM on the fiber optic line;
reserving the downstream ROADM for the loading of the first optical service by preventing the downstream ROADM from loading a second optical service on the fiber optic line and disabling one or more control block of the downstream ROADM, thereby preventing the one or more control block from adjusting a configuration of the downstream ROADM; and
loading, by the local ROADM, the first optical service on the fiber optic line.
