| 摘 要： | 利用实时操作系统VxWorks提供的标准socket接口和多任务机制,实现了基于TCP/IP协议的多网卡数据通讯;在应用程序中通过对网卡的动态添加删减,实现了双网卡共享IP和物理地址的冗余备份.介绍了在VxWorks环境下,PC-104寄生网卡82559与双NE2000的多网卡数据传输和双NE2000网卡的冗余备份.在应用程序中实现对冗余网卡驱动的添加删减,避免了对BSP底层驱动的二次开发,缩短了开发周期和费用,具有较强的实用价值.

| Abstract: | By meanssof a standard socket and and the multi-task method of VxWorks, the multi-network card communication based on the TCP/IP protocol is realized. The method of adding and deleting a network card dynamically in a program can bring about a dual-redundance net, which uses the same IP and physical address. The paper gives an example, in which both 82559 and NE2000 are used to realize the multi-net communication and the dual-redundance backup of the dual NE2000 network card. The said method is of highly practical value, which avoids the second development of a board packet, thus reducing the developing period and cost. |
