How virtual server works?
Now virtual server is implemented in three ways. There are three IP load balancing techniques (packet forwarding methods) existing together in the LinuxDirector. They are virtual server via NAT, virtual server via IP tunneling and virtual server via direct routing. Please see the three separate sections for their working principles and configurations. How to build the kernels and how to use them are also explained in details there too.
现在虚拟服务器以三种方式实现。LinuxDirector中存在三种IP负载平衡技术 (数据包转发方法)。它们是通过NAT的虚拟服务器，通过IP隧道的虚拟服务器和通过直接路由的虚拟服务器。请参阅三个单独的部分，以了解其工作原理和配置。那里还详细说明了如何构建内核以及如何使用它们。
The following subsections will explain their advantages and disadvantages. The comparison of VS/NAT, VS/TUN and VS/DR is summarized in the following table.
以下小节将解释它们的优缺点。VS/NAT、VS/TUN和VS/DR的比较总结如下表。
