A data synchronization method, in a network element operating in a network, includes generating an event at the network element that needs to be synchronized with other devices in the network; based on assigned tokens for the network element, generating a row key for the event; and providing the row key to a Highly-Available (HA) key-value storage system for synchronization therewith, wherein the HA key-value storage system includes a plurality of nodes including the network element and the other devices.

The present disclosure provides improvements with respect to in-band control plane signaling, virtualized channels, and tandem connection monitoring in optical networks utilizing Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), Optical Transport Network (OTN), and the like. In an exemplary embodiment, the present disclosure includes an optical network operating a control plane with in-band signaling utilizing SONET/SDH path level overhead. In another exemplary embodiment, the present disclosure includes an optical network operating virtualized SONET/SDH or OTN channels with manually cross-connections at intermediate line terminating elements. In yet another exemplary embodiment, the present disclosure includes a tandem connection monitoring selection method across multiple operator domains.
