Abstract
A control apparatus, includes a first unit configured to be capable of specifying an identification rule to identify a packet based on a user of a virtual network including a plurality of virtual nodes; and a second unit configured to be capable of sending an instruction to a physical node corresponding to each of the virtual nodes of the virtual network, wherein each of the virtual nodes includes a predetermined network function being capable of providing a first packet operation to the packet, wherein the instruction includes that the physical node provides a second packet operation to the packet so as to emulate the first packet operation.
