Aiming at the real-time network system design, the real-time network design method is put forward based on the reflection memory. The principle of using the reflection memory to effect real-time communication and the formation method of real-time network based on the reflective memory card （ VMI-5565 ） is introduced. The allocation method of two reflective memory address and the communication process are analyzed and the real-time communication protocol is given as well. At the same time, the method of realizing real-time communication under Windows system is briefly explained. Finally, the qualitative analysis of this real-time network＇s performance and the actual test results are presented.
