| Abstract: | This paper analyses the structure of data link layer and network layer in embedded real-time OS VxWorks, and expatiates how to realize the redundancy of NIC in the driver at the bottom of OS. Finally, the effects of the technology used in the driver layer and in the application layer respectively, are compared.It is proved that better effect can be obtained if the method is used in the driver. |
