Abstract
Echo messaging for operation, administration, and management of a service-based distribution path and associated services are disclosed. Service-based distribution paths or transport tunnels include services mapped or bound to a path associated with the transport tunnel. Echo messaging provides OAM capabilities to monitor the operational state of a service-based distribution path, including determining configuration, connectivity, and other characteristics of the path and associated services that transport data. OAM functions provided by echo messaging enable OAM functions despite service volume along a core network, path or set of paths.
