Abstract
A method for operating a u-MANO inside a user domain that ensures deployment and service integrity of end-to-end network services in collaboration with a p-MANO includes receiving a request for a network service instance; and initiating a discovery operation to discover the p-MANO if the request's scope is determined to extend beyond the user domain. The discovery operation includes: determining an identity and/or an address of the p-MANO; sending a solicitation message to the p-MANO to discover its reachability and availability; sending a service request specifying network service requirements to the p-MANO in response to receiving a solicitation response from the p-MANO; and receiving a service acceptance from the p-MANO. The method further includes instantiating and deploying the network service instance that is at least partially within the user domain and partially outside the user domain.
