响应时间过滤器WCF，负载均衡， [英] Response time filter WCF, load balancing ,

问题描述

我正在进行负载均衡;

i已经计算了每3秒内所有服务器的响应时间

，而我正在使用循环法，如何根据最低响应将客户端的请求发送到服务器时间？我只是想在其中一个服务器变慢的情况下这样做，所以我可以减少它的负载。



再次谢谢你

请帮帮我

谢谢^ __ ^



我尝试了什么：



i考虑动态更改优先级但是rooter应该每次重启在app.config中应用新配置

解决方案

我看到有两种方法......

一 - 成为代理在客户端和服务器之间 - 在这种情况下，您可以测量响应时间并确定哪个服务器最快并在下一轮中使用...虽然有可能我不会使用它，因为所有代理事情都相当复杂有性能损失..

两个 - 使用性能计数器（ PerformanceCounter构造函数（String，String，String，String）（System.Diagnostics） [ ^ ]） - 也许已经有了，或者你可以写自己的（如何：创建自定义性能计数器 [ ^ ]） - 检查每个服务器的最后/平均响应时间是多少并选择最佳...我会推荐这个......

Hi , I am working on load balancing ;
i already calculate the response time of all my servers in every 3 s
,while i am using round-robin,how to root the client's requests to the server with lowest response time? I just want to do this in case one of the servers is getting slow,so i can reduce its load.

and thank you again
Please help me
Thanks ^__^

What I have tried:

i thought about changing the priority dynamically but the rooter should restart every time to apply the new configuration in app.config

解决方案

As I see there are two ways...
One - to become a proxy between the client and the server - in this case you can measure the response time and decide which server is the fastest and use in the next round... While it is possible I would not use it as all that proxy thing is fairly complicated and has performance penalty..
Two - use a performance counter (PerformanceCounter Constructor (String, String, String, String) (System.Diagnostics)[^]) - maybe there is one already, or you can write your own (How to: Create Custom Performance Counters[^]) - to check what is the last/average response time of each server and pick the best... I would recommend this one...
