1. An apparatus for generating a Software Defined Network (SDN)-based virtual network by reflecting user demands, the apparatus comprising:
one or more generators, a collector, and a calculator being configured and executed by a hardware processor using algorithms associated with at least one non-transitory storage device, the algorithms, when executed, causing the hardware processor to execute the generators, collector, and calculator, the one or more generators comprising, a network information generator configured to collect characteristic information on communication equipment connected to a network and to generate information required to determine a network path; and in response to receipt of user demands relating to at least one of changing a geographical location, calculating a unit price of a service, calculating stability of services, and calculating latency of services of the communication equipment, a virtual network generator configured to determine a physical path of the network based on the generated information, and to allocate physical resources by generating a virtual switch which is capable of determining the physical path, wherein access switches and backbone switches included in the determined physical path are virtually controlled using the virtual switch. |
