| 摘 要： | 分析了VxWorks系统下的SENS协议栈，设计了位于MUX层与网卡驱动层之间的虚拟网卡来管理两个互为冗余的物理网卡，设计了链路监测单元和链路切换单元来保证链路切换的快速性和准确性，设计了单IP和单MAC地址的设置方式，实现了虚拟网卡在不同系统中对双冗余的兼容性要求。测试结果表明该方案保证了虚拟网卡的通用性与各个模块的独立性。能够在网卡出现故障时及时准确的切换至备用链路。

| Abstract: | The SENS protocol stack under VxWorks system is analyzed in this paper,which designs a virtual NIC between the MUX layer and NIC driver layer managing the two mutual-redundant physical NICs,a link monitoring unit and a link switch unit ensuring the rapidness and accuracy during link switching and the setting mode for the single IP and the single MAC address;therefore,the compatibility of the dual-redundancy virtual NIC in different system is realized.The test result reflects that the scheme ensures the univ... |
