The current market of IOT is confronted with two main characteristics.The first is chimney type
it refers that IOT application system is a is a relatively closed system from the terminal to the application platform
its computation
communication and network capacity are served only to the system itself
and not shared with other systems
which causes longer development cycle and higher cost.The second is fragmentation
it refers that the IOT market is isolated to meet the individual requirements of customers
and could not be copied to other customers
which results in that the scale of terminal is small
and the deployment cost of the IOT system is too high.It has been proved by the development history of communications and network that standardization is an effective solution to the chimney type and fragmentation.This article introduces the standard system of IOT from three facets
