双冗余网卡的设计

Design of dual-redundance network card

网络通信是现代系统通信的主要方式,而网卡是网络的核心部件,如果网卡出现故障,整个网络系统将处于瘫痪的状态。为了提高通讯网络的可靠性,现代网络系统引入冗余网络构架,其中双冗余网卡是该系统的核心。本文介绍了一种双冗余网卡的组成及工作原理,同时介绍了网卡冗余的实现过程。

Net is important in the modern system of communications , and network card is a core in the network . If the network card fails, the whole system will be in paralysis conditions. To improve the reliability of the network communications , the modern network system brings the framework of redundance net , in which the dual-redundance network card is the key part. In this paper, we introduce the makeup, operating principle and the realization of the dual-redundance network card .
