In this paper firstly, vehicle are shown): traditional inter-communication system for underwater vehicle (UV) is introduced and it has its intrinsic shortcomings. So in A. Device layer order to overcome those shortcomings a developed Ethernetbased inter-communication system has been designed and t Devce layer belongs to low-level control layer. And implemented. Secondly, various network data transmission delay there are mainly functions in this layer network: supplying testing on our semi-physical virtual simulation platform verifies power to some sensors and actuators, collecting analogy of the reliability and its performance of the whole network. And digital data of sensors and receiving commands then control software is also developed and the results of the auto-sending signals to actuators (camera, thrusters and weight heading are shown. At last, the results of analysis and test release etc.). The common used networks in this layer indicate that this Ethernet-based inter-communication system include: RS-485 bus (CR-01), Intelligent communication has a good performance and now we are ready to sea board-MVC-16 (SAUVIM, 2003), CAN-bus (Alberto experiments for thefuture. ' Index Terms-Ethernet, Manned submersible vehicle, real-Ortiz& Julian Proenza) etc. time.
