| Abstract: | Distributed test system communication features ware introduced.Analyzed switched-Ethernet work way,and end-to-end communication delay of switched Ethernet.Under the Test system in real-time transmission requirement,a UDP-based for the test field of RUT(Reliable UDP for Test System) reliable transmission protocol was proposed.By setting receive buffer,sent buffer and data confirming ensure reliable transmission.After testing the transmission protocol has better real-time and reliability,and applied to the field of industrial measurement and control. |
