With increasing demands of performing arts, more and more types and numbers of lighting devices are adopt on stage. How to access and control these abundant devices become serious problems. Nowadays, networked control system of stage lighting device is a research focus in entertainment technology field. A more intelligent and realtime automatic networking of stage lighting devices is expected. In order to construct a universal, feasible and compatible devices network automatically, architecture of network standard protocol is proposed in this paper, which including several key aspects: device discovery, device identification, device description, device management and session data transmission. At the same time, the working mechanism and sub protocols are analyzed separately.
