发布时间：2018-09-10 08:13
【摘要】：负载均衡通过将大量的并发访问请求转发到多个服务器分别进行处理,以提高web集群的整体吞吐量.现有的负载均衡算法存在着引用负载因素过少、负载计算过于复杂、节点的负载抖动现象过于严重等问题.本文提出一种改进的动态告警负载均衡算法,基于请求类型、节点工作能力和实时负载值来确定转发目标.该方案实时监测各节点的负载状态并实施周期性反馈与动态告警,既保证了负载信息的实时性与有效性,又减少了负载计算量;采用RED方法校正负载状态的判定,避免了因为负载状态的误判而引发的负载不均,从而减小了负载抖动现象.模拟实验结果表明,改进算法增加了web集群系统的吞吐量,并且明显改善了负载均衡度.
[Abstract]:Load balancing improves the overall throughput of web clusters by forwarding a large number of concurrent access requests to multiple servers for processing separately. The existing load balancing algorithms have many problems, such as too few load factors, too much complexity of load calculation, too serious load jitter phenomenon and so on. In this paper, an improved dynamic alarm load balancing algorithm is proposed to determine the forwarding target based on request type, node working ability and real-time load value. The scheme monitors the load state of each node in real time and implements periodic feedback and dynamic alarm, which not only ensures the real-time and efficiency of load information, but also reduces the load calculation, and uses RED method to correct the judgment of load state. The load imbalance caused by the misjudgment of the load state is avoided and the load jitter is reduced. The simulation results show that the improved algorithm can increase the throughput of web cluster system and improve the load balance obviously.
