网管入门8139网卡实现双网卡负载均衡bja 网管入门:8139网卡实现双网卡负载均衡 虽然现在市面上有天生能够绑定的网卡，但作为廉价网卡突出代而拥有大量用户端的8139网卡却不支持这项功能，不过不要着急，只要安装一个小软件——“NICExpress”，就可以用普通的8139之类的网卡体验一把双网卡绑定的愉悦了。 朋友或许会问了，为什么要用双网卡呢,用双网卡有什么好处,所谓双网卡，就是通过软件将双网卡绑定为一个IP地址，这个技术对于许多朋友来说并不陌生，许多高档服务器网卡(例如intel8255x系列、3COM服务器网卡等)都具有多网卡绑定功能，可以通过软硬件设置将两块或者多块网卡绑定在同一个IP地址上，使用起来就好象在使用一块网卡。 多网卡绑定的优点不少，首先，可以增大带宽，假如一个网卡的带宽是100M，理论上两块网卡就是200M，三块就是300M，当然实际上的效果是不会是这样简单的增加的，不过经实际测试使用多个网卡对于增加带宽，保持带宽的稳定性肯定是有裨益的，如果交换机等相关条件不错的话，这个效果还是很能令人满意;其次，可以形成网卡冗余阵列、分担负载，双网卡被绑定成“一块网卡”之后，同步一起工作，对服务器的访问流量被均衡分担到两块网卡上，这样每块网卡的负载压力就小多了，抗并发访问的能力提高，保证了服务器访问的稳定和畅快，当其中一块发生故障的时候，另一块立刻接管全部负载，过程是无缝的，服务不会中断，直到维修人员到来。 OK，现在就手把手的教大家如何用50元来打造出双网卡的效果～ 先下载软件(点击这里下载NIC Express Enterprise)，这是4.0版本，只有2.15M，软件的兼容性已经做得很好，支持win98/Me/2000/XP/2003。基本上支持目前市场上常见的各种网卡，百兆和千兆网卡都可以用来绑定，但是千万注意，最好用于绑定的网卡是完全相同的，至少也是基于同一芯片的，这样多块网卡才能合作得比较好。切记不要把10M网卡和100M网卡绑定在一起，那样根本起不到提升作用。 下载完软件，先不忙安装，咱们还是先准备好硬件。 第一部分:硬件安装 虽然，理论上讲绑定越多网卡在一起，最终效果提升就越明显，但是考虑到复杂程度，这里就以绑定双网卡为例进行说明，如果读者觉得好玩，兴致很高的话，按照下面方法愿意绑定多少就绑定多少个网卡，其实一般同一台服务器，绑定2,3块网卡也就够了，太多了，据说因为链路聚合的先天缺点，会过多占用urban area 2.5.2 Yibin city in Yibin city, according to resource and environment characteristics Urban population and urban spatial distribution, spatial distribution of industries, major infrastructure Corridor layout, combined with the future development trend of synthetic judgments, planning, urban spatial structure of urban system can be summarized as: "a pole along the two axes".
