| Abstract: | All kinds of real-time data,such as video signals,field control signals,needto be transferred in time.To address this problem,an hybrid working mode is presented anda priority transfer protocol(PTP) is adopted.It is proved that this method can ensure thereal-time data transfer in all nodes without increasing more overhead. |
