摘　　要：网络通信是现代通信系统领域的主要方式。网卡作为网络通信系统的关键组成部分,一旦发生故障,将导致整个网络通信系统的全部崩溃而不能工作。实现双冗余式网络构架是提高现代网络通信系统的可靠性和稳定性的一种重要方式,而双冗余网卡则是其中核心。文章简要介绍了一种双冗余网卡的实现机理、技术指标、结构特征、硬件组成以及软件描述。Network communication is the main way in modern communication systems. As the core component of network communication system, once the net card fails, the whole network communication system will collapse and can not work. Dual redundant network architecture is an important way to improve the reliability and stability of modern network communication system, of which dual redundant NIC is the core. This paper briefly describes the implementation mechanism specifications, structural features, hardware composition and software description of a dual redundant net card.
