Web应用的无所不在迫使服务器不得不支持比以往更多的访问用户,并要求它具有每时每刻的可用性;必须具备提供大量并发访问服务的能力,其处理能力和 I/O 能力已经成为提供服务的瓶颈。负载均衡作为一种策略,能够让多台服务器或多条链路共同承担一些繁重的计算或 I/O 任务,从而以较低成本消除网络瓶颈,提高网络的可靠性以及灵活性。网络负载均衡技术是一种动态均衡,通过一些工具实时地分析数据包,掌握网络中的数据流量状况,把任务合理均 The ubiquity of Web applications forces servers to support more users than ever before, requiring them to be available at all times; must have the ability to provide a multitude of concurrent access services whose processing power and I / O capabilities have become services Bottleneck As a strategy, load balancing can share heavy computational or I / O tasks with multiple servers or multiple links, eliminating network bottlenecks and improving network reliability and flexibility at a lower cost. Network load balancing technology is a kind of dynamic equilibrium, real-time analysis of data packets through some tools to master the data traffic conditions in the network, the task is reasonable
