US Patent 7835894 System and method for simulating home network

A system and method are provided for simulating a home network, in which elements of the home network are implemented by software even before the home network is equipped with all necessary elements, so that a user can simulate the home network through a graphical user interface. The system includes: a client having a graphical user interface through which a user inputs a control message which controls a device and recognizes a response message to the input control message; and a server transmitting a device entity corresponding to the input control message, and selectively transmits multiple response messages to the client in response to the received control message.
