Abstract: A network node apparatus for Information-Centric Networking (ICN) and an operating method thereof. The network node apparatus has a control plane and a data plane, which are separate from each other, and manages location information of content on the data plane concentratedly. For example, the network node apparatus includes a Content Service Coordination Function (CSCF) configured to process a content request from a user or a publication request from a content provider; a Content Delivery Control Function (CDCF) configured to select an optimal service node to handle the content request or the publication request; and a Content Delivery Service Function (CDSF) configured to download requested content to the user or to download from the content provider content requested to be published and then register the downloaded content.

Abstract: A system for chaining a virtualized network function according to an example comprises: a forwarder configured to receive an input packet; and a broker configured to detect NFP_id of the input packet by referring to a network forwarding path (NFP) mapping table provided by an orchestrator and transfer the NFP_id and data of the input packet to a virtualized network function (VNF), wherein the broker receives a downlink packet including the NFP_id, branch_id and data from the VNF, constructs a header in accordance with the NFP_id or next NFP_id which corresponds to the branch_id on the NFP mapping table, and transfers an output packet including data included in the downlink packet and the header to the forwarder, wherein the forwarder transfers the output packet in accordance with the header of the output packet.
