摘要
网络负载均衡在现代企业中的实现与应用
【摘 要】21世纪以来随着Internet和Intranet的高速发展，网络给人类生活带来很大的便利，人们在生活中越来越离不开网络了。每天都有几十亿的人在用到网络，网上购物、网上订餐,甚至连水费、电费都可以通过简单的链接几分钟搞定。而在这背后却是企业网络承受的压力越来越大。例如2014年阿里巴巴集团旗下的天猫在双十一的成交额为571亿元，那天24小时内有2.78亿笔交易，更让人惊叹的是在那天凌晨零点到一点这一小时的交易额为122亿，成交的订单为6283万笔。一小时的访问服务器人数是一个巨大的数据，将会造成服务器的拥堵，网络的瘫痪。而在现实生活中也没有任何硬件可以满足这些需求，并且完成任务。所以人们就发明了网络负载均衡的技术来解决这一系列问题。

ABSTRACT
Network load balancing implementation and application in
modern enterprises
【Abstract】 Since the 21st century, along with the rapid development of Internet and Intranet, the network has brought great convenience to human life. Today the Internet has become something essential in our work and daily life. Billions of people are online every day, such as online shopping, online meal ordering, and even the payment of water and electricity are available through a simple link in a few minutes, which result that the pressure on the corporate network is growing. For example, the turnover of Tmall which is under Alibaba Group reached 57.1 billion in November 11th,2014, and completed 278 million transactions within 24 hours in that day. Even more, the trading in the first hour that day amounted to 12.2 billion, and the number of transactions reached 62.83 million, this incredible data reflect the number of people who access to the server in one-hour is so huge, which will result in server congestion and network paralysis. However, there is no hardware can meet so many needs successfully. Thus the network load balancing technology is born to solve these problems.
