Abstract: Techniques are disclosed herein for reconciling planned data for a network (such as a fiber optic network) with data describing the deployed network. Network probing and planning components obtain a snapshot of the deployed network and organize the snapshot into three “layers”: the “link layer,” which represents the physical links that underlie the network, the “digital layer,” which includes optical channel groups that divide the total capacity of the physical links, and the “service layer,” which includes the services delivered over the network. The techniques involve comparing the planned data to the deployed data in the order of link layer, digital layer, and service layer. Differences considered to be “minor” are reconciled automatically. Differences that are “major” are reconciled after receiving instructions from a planner or administrator regarding whether to update the planned data based on what was originally in the planned data or what is in the deployed network.
