Wired/wireless integrated open fronthaul device

An open fronthaul device comprising:

• a software defined network (SDN) controller including a plurality of openflow edge switches connected to a plurality of legacy networks, which are wireless access networks or wired access networks, in which the openflow edge switches are configured to acquire information of the openflow edge switches belonging to a switch group;
• and
• a legacy routing container configured to treat a switch group including at least some switches among the switches as a virtual router to generate routing information for a packet introduced into any one switch of the switch group, wherein the legacy routing container is configured to map a plurality of network devices, which are connected to the openflow switches configured to generate legacy routing information for a flow processing inquiry message of the controller based on information of at least one virtual router, with information of an external network that is directly connected to the virtual router, and
• the controller includes:
• a time synchronization module configured to synchronize a time of the packet with a timestamp value of the network device;
• a policy manager module configured to control a Quality of Service (QoS);
• and
• a deep packet matching module configured to extract, modify, remove, or insert a GTP header or a VxLAN header of a flow packet.
