摘要

负载平衡器在企业数据中心中扮演着至关重要的角色,因为它们的存在和性能对服务的提供和可用性至关重要。目前的技术水平是,负载平衡器是一种专用的嵌入式硬件,具有专有的操作系统和应用程序模块。在本文中,我们提出了一个概念来打破这个黑盒模型,并展示了如何使用OpenFlow技术开发高性能LB。在这种方法中,我们使用OpenFlow网络组件来处理负载平衡,以减少维护工作量和降低硬件成本因素。此外,在故障转移的情况下,它在概念上是冗余的,并且更容易被另一个设备取代。对该概念的实验评估证明,该概念已经超越了理论概念,实现的解决方案已经准备好部署。

Optimizing openflow load-balancing with L2 direct server return
Load-balancers have an essential role in enterprise data-centers, as their existence and performance is decisive for service provision and availability. The state of the art is that today's load-balancers are a piece of specialized embedded hardware with a proprietary operating system and application modules. In this paper we propose a concept to break up this black box model and to show how to develop a high performance LB with OpenFlow technology. In this approach we use OpenFlow network components to process the load-balancing and in order to reduce the maintenance effort and to lower the hardware cost factor. Furthermore, in case of fail-over it is redundant by concept and easier to replace by another device. The experimental evaluation of this concept proves that the concept is developed beyond a theoretical concept and the implemented solution is ready for deployment.
