摘要：
传统用于服务器集群的负载均衡器存在缺乏灵活性、成本高等问题。为了克服这些问题，已有研究将基于软件定义网络（SDN）的负载均衡器应用于服务器集群。在这一趋势下，本文提出了一种在使用SDN的服务器集群中具有故障转移能力的混合负载均衡方法。本文的主要目标是提高负载均衡的性能和故障转移能力。首先，我们通过采用二分搜索来查找目标服务器，改进了动态加权随机选择（DWRS）算法的性能。接下来，我们通过将改进的DWRS算法与快速故障转移（FF）组表相结合，提出了一种具有故障转移能力的动态方法。此外，还提出了一种混合方法，将使用SELECT组表的静态方法与具有故障转移能力的动态方法相结合，以提高性能。最后，在实验环境中评估了所提方法的故障转移能力和性能。
英文摘要：
Traditional load balancers used in server clusters have problems such as lack of flexibility, high cost, etc. To overcome these problems, research has been conducted to apply a load balancer using software-defined network (SDN) to the server cluster. Under this trend, in this paper, we proposed a hybrid load balancing method with failover capability in the server cluster using SDN. The main goal of this paper is to improve the performance and failover capability of load balancing. First, we improved the performance of the dynamic weighted random selection (DWRS) algorithm by adopting the binary search to find the target server. Next, we proposed a dynamic method with failover capability by combining the improved DWRS algorithm with a fast-failover (FF) group table. In addition, a hybrid method combining the static method using the SELECT group table and the dynamic method with failover capability is proposed to improve the performance. Finally, the failover capability and performance of the proposed method are evaluated in an experimental environment.
