很多大型的门户网站,如搜狐、网易等,它们的访问流量通常相当大,某一时间段内可能有成千上万的用户同时浏览某个页面,为了使这些门户网站正常运营,它们大多使用多台服务器同时来处理用户的访问请求,将这些巨大的访问量平均分配到不同的服务器上,这就是所谓的网络负载均衡技术。透过现象看本质毕竟网络负载均衡技术是门高深的技术,一般用户是很难理解的,到底哪些网络服务或者网站使用了该技术呢?其实这个也是很好判断的,通过一个简单的Ping命令就可以知道。下面笔者以“www.sohu.com(搜狐)”为例,看看Ping命令所得的IP地址结果有什么不同。在“命令提示符”窗口中, Many large portals, such as Sohu, Netease, etc., usually have quite large traffic, and may have tens of thousands of users browsing a certain page at a time. In order to make these portals operate normally, most of them use Multiple servers at the same time to deal with user requests for access, these huge visits evenly distributed to different servers, which is the so-called network load balancing technology. After all, the essence of the phenomenon through the network load balancing technology is the door of the deep technology, the average user is difficult to understand, in the end what network services or websites using the technology? In fact, this is also a good judge, through a simple Ping command You can know. The following author “www.sohu.com (Sohu) ” as an example, take a look at the Ping command IP address results obtained what is the difference. In the “Command Prompt” window,
