摘　　要：酒店智能终端系统中,为了解决随着终端用户数量的增加导致的服务器负载过重从而用户满意度下降的问题,提出了一种改进的加权最小连接调度算法的负载均衡技术,将连接个数作为负载因子进行综合考虑,使得新加入的终端用户能够自动在多云分支服务器之间做出最佳决策,选取当前周期内负载最轻的一台服务器进行自动连接并实现整个酒店智能系统的负载均衡。实验结果表明,利用改进算法可以使得酒店智能终端机顶盒与多云分支服务器的自动连接实现整个系统的负载均衡且具有良好的稳定性,达到了预期效果。In the hotel intelligent terminal system,in order to solve the problem of the overloading and the user satisfaction degree decreasing because of the increasing number of the user, an improved load-balancing algorithm based on the weighted least connection is presented. This method considered the connection number of the system as well as the load factor which made the new user could make the best choice to connect to the lightest load cloudserver in the current cycle automatically and achieve the load-balancing of the whole system. Experiments showed that this improved algorithm could make the automatic connection of the hotel intelligent terminal set top box and the branches of cloud-server to achieve the load balancing of the whole system and has a good stability that confirmed the expected idea.
