Abstract: A transparent optical overlay network (1) for providing end-to-end optical spectrum services over multiple transparent optical network domains (2) is described. The transparent optical overlay network (1) includes network domain interface devices, NDIDs, (3) provided at domain boundaries between adjacent transparent optical network domains (2). The network domain interface device, NDID (3), monitors and adjusts incoming optical signals received by the NDID (3) from a first transparent optical network domain (2-1) and monitors and adjusts outgoing optical signals output by the NDID (3) to an adjacent second transparent optical network domain (2-2). An overlay network controller (5) manages and controls the end-to-end optical spectrum services by controlling the NDIDs (3). The overlay network controller collects telemetry data (TDATA) for optical spectrum service characterization and SLA policing of the optical spectrum services.
