Abstract
A data center network system based on software-defined network (SDN) is provided. The data center network system includes a plurality of physical machines, a plurality of Ethernet switches, a plurality of OpenFlow switches connected to each other, and a central control apparatus. Each of the physical machines includes a virtual switch and at least one virtual machine. The virtual switches modify destination media access control (MAC) addresses of packets to MAC addresses of the OpenFlow switches, such that the Ethernet switches forward the packets received from the virtual switches to the corresponding OpenFlow switches according to the MAC addresses of the OpenFlow switches. The OpenFlow switches modify the destination media access control (MAC) addresses of the packets to MAC addresses of virtual machines, such that the Ethernet switches forward the packet received from the OpenFlow switches to the corresponding virtual switches.
