说明：  使用C++/QT实现了一个负载均衡，有三个程序，Client, Server, Loder，运行过程中可以开多个客户端和多个服务器，一个负载均衡，使用多个客户端发送多条数据的时候，负载均衡器使用轮转法将消息推送给空闲服务器，服务应答消息传给负载均衡器，由负载均衡器发送给客户端
(Using C++/QT implements a load balancing, there are three procedures, Client, Server, Loder, running you can open multiple clients and multiple servers, a load balancing, use multiple clients to send more data, Round Robin load balancing using the message pushed to the idle server, service response message passed to the load balancer, the load balancer sends to the client)
