说明：  This paper analysed the kernel of embedded real-time operating system ARTs-OS. And then we discussed the framework of network system and its way of work. From the basic functions ARTs-OS micro-kernel provides, we developed the basic strategy to achieve TCPIP protocol stack according to the way of the process of network services, provide the network communication function outside the core To run multiple threads in network services process and distribute the module to a number of threads to achieve the final function Using the way of message loop to receive service requests the application
