Abstract
The technology of network redundancy switching backup mostly works with the control chip running with embedded operating system.The application of this technology can effectively increase the reliability of network data transmission,but the speed of network switching is a big problem.In this paper,firstly the control chip MPC8377 running with Linux system,CPLD and 2 pieces of 88E111 (PHY)complete the design of the network redundancy backup.Then the corresponding software is designed.Thus the time of the net-work switching is less 20 ms.In this way,the switching speed is improved and makes the transmission more reliable.关键词
