1. A method of operating a network domain controller in a communication system, the method comprising:
receiving node information, link information, adjacent node information, and adjacent node link information from a network node control agent;
identifying controller topology information based on the node information, the link information, the adjacent node information, and the adjacent node link information; and
transmitting boundary node information, boundary node link information, adjacent domain node information, and adjacent domain node link information to a network orchestrator,
wherein the controller topology information comprises:
complete node configuration and connection information of all network nodes within a network domain; and
internal node and link information within the network domain, which is not shared with the network orchestrator.
