SuperKEKB is the upgrade of the KEKB asymmetric energy electron-positron collider, for the next generation B-factory experiment in Japan. It is designed to achieve a luminosity of 8x1035/cm2/s, 40 times higher than the world highest luminosity record at KEKB. For SuperKEKB, we upgrade the accelerator control network system, which connects all devices in the accelerator. To construct the higher performance network system, we install the network switches based on the 10 gigabit Ethernet (10GbE) for the wider bandwidth data transfer. Additional optical fibers, for the reliable and redundant network and for the robust accelerator control timing system, are also installed. For the KEKB beamline construction and accelerator components maintenance, we install the new wireless network system based on the Leaky Coaxial (LCX) cable antennas into the 3 km circumference beamline tunnel. We reconfigure the network design to enhance the reliability and security of the network. In this paper, the design and current status of the SuperKEKB accelerator control network system will be presented.
