It consists of two container nodes: hicn-conf and hicn-state. One is used to hold the +configuration data (i.e., hicn-conf) and one for providing the state data (i.e., hicn-state). The hicn-conf has one node, params, which contains the hICN configuration parameters. Controler can configure these parameters through the edit-config RPC call. This node can be used to enable and to initialize the hicn-plugin in VPP instance. Hicn-state container is used to provide the state data to the controler. It consists of state, strategy, strategies, route, and face-ip-params nodes with the coresponding leaves. In hicn model variety of RPCs are provided to allow controler to communicate with hicn-plugin as well as update the state data in hicn-state.

This configuration can be changed through the controler by subscribing which changes the target to the running state. hicn yang model provides a list of RPCs which allows controler to communicate directly with the hicn-plugin. This RPCs may also cause the modification in state data.
