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

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
