随着网络技术日新月异的发展,人们的生活对于网络的依赖度越来越高,这就要求网络服务器性能的不断提升,来进行高效的网络服务处理.但是,仅仅通过一台高性能计算机进行处理已经很难满足与日俱增的网络服务质量要求,于是,网络服务器集群的概念应运而生.网络服务器集群的出现大大解决了以前单一服务器处理服务的能力不足的问题,它通过众多服务器同时处理大量的用户请求,大大缩短了时间,也为服务器节约了寿命.
网络服务器集群技术日趋成熟,人们渐渐对于整个集群的性能又提出了要求,负载均衡的概念在这时被提了出来.现如今已经有很多成熟的负载均衡算法以及结构完善的负载均衡集群.主要有基于镜像站点的网络服务器集群、基于DNS的网络服务器集群、基于请求分配器的网络服务器集群和基于服务器端的网络服务器集群.
本文在介绍网络服务器集群发展现状的同时,对基于DNS的网络服务器集群和基于请求分配器的网络服务器集群进行了MATLAB软件仿真.仿真过程中用Simulink平台中的模块搭建网络服务器集群的架构,来仿真一次请求处理的过程网络服务器集群性能的表现.
仿真结果表明,基于DNS的网络服务器集群结构上更为简便,在假设条件下处理请求所用时间最短,而基于请求分配器的网络服务器集群稳定性更强.
而结合实际情况考虑后,分析得出基于请求分配器的网络服务器集群具有更好的性能,它能提供细粒度的负载均衡,有更好的容错性,有更好的运作机制.同时,在现实生活中它也是应用最广泛的.

Development changes with each new day which along with the networking,people's life is more and more high regarding the network dependence,this request network server performance unceasing promotion,carries on highly effective network service processing.But,merely carries on the network grade of service request through a high performance computer which processing already very was difficult to grow day by day satisfiedly,therefore,the network server cluster's concept arose at the historic moment.The network server cluster's appearance has greatly solved the problem which before sole server processing service ability was insufficient,it requested through the multitudinous server simultaneous working massive users,reduced the time greatly,also saved the life for the server.
The network server cluster technology is day by day mature,the people also proposed gradually regarding the entire colony's performance the request,the load equalization concept in has been proposed by now.Nowadays already had the load equalization colony which the very many mature load equalization algorithm as well as the structure consummate.Mainly has based on the mirror image stand network server cluster,based on the DNS network server cluster,based on requests the divider the network server cluster and based on the server end network server cluster.
This article during introduction network server cluster development present situation,to based on the DNS network server cluster and based on requested the divider the network server cluster has carried on the MATLAB software simulation.In the simulation process with the Simulink platform in module build network server cluster's construction,comes a simulation request processing the process network server cluster performance performance.
The simulation result indicated that,is simpler based on in the DNS network server cluster structure,processes the request under the supposition condition to use the time to be shortest,but based on requested the divider the network server cluster stability is stronger.
But after unifies the actual situation consideration,the analysis obtains based on requested the divider the network server cluster has a better performance,it can provide the fine grain the load equalization,has a better fault tolerance,has the better operation mechanism.At the same time,it also is applies widely in the real life.
