- Forwarding Construct: The Forwarding Construct (FC) class models enabled constrained potential for forwarding between interfaces at a particular specific layerProtocol.
- FC Port: Fowarding Construct Point. The association of the FC to interfaces is made via FC Ports. The FC Port class models the access to the FC function.
- Node: Node resource, it could be a site or a network element or anything else which can be a host for endPoint or any other node.
- FC Route: The routing relationships within FC are described, including routing between sub FC (interdomain links), and links between network elements, and exchange relationship within network elements. SubFc describes the lower level FC. FC objects support a recursive aggregation relationship such that the internal construction of FC can be exposed as multiple lower level FC objects (partitioning). Lower level FC could belong to different domain, which is useful for cross domain FC.
- Link Connection: The exchange relationship between nodes, describing how the interfaces between nodes are linked. The link can depend on the FC of the service layer, such as overlay network depend on underlay network.
- XC: Exchange Connection. The exchange relationship within a node describes how the interfaces within the node are linked.
- XC Point: Exchange Connection Point. Interfaces involved in exchange in a node or a link.

Node | ONF Core Im: ForwardingDomain(TR-512.DD_OnfCoreIm-DataDictionary.pdf 2.1.1.11 ForwardingDomain ) & TMF513_v3.1: Equipment (TMF513_v3.1_070314.pdf 4.1.25 Equipment) | Works as an extension for ONF Core Im. Forwarding Domain contains resource for FC. And higher level FD could encompass lower level FD. Besides, equipment could encompass FDs. Both FD and Equipment have the capability to be the host of resources which work for FC. Node is the abstract class for them. |
