Abstract
A software defined network (SDN)-based network management apparatus includes: an SDN controller including a first management unit to store a plurality of heterogeneous protocol information items, and an SDN switch controlled by the SDN controller and including a second management unit to store at least one heterogeneous protocol information item acquired from the SDN controller and a gateway to communicate with a vehicle network. In particular, upon receiving a packet corresponding to a new protocol that has not been used for access, from an external source, the SDN switch sends a request to the SDN controller for analysis of the received packet, and the SDN controller forwards protocol information corresponding to the received packet among the plurality of heterogeneous information items stored in the first management unit, to the SDN switch.
