摘要
由于用户驱动实验的范围无限,在未来互联网测试平台环境中管理服务实现实验的生命周期是非常具有挑战性的。实验的生命周期应在用户和操作者之间仔细设计和管理,以便在所有实验阶段都明确定义任务和责任。还应适当地管理所涉及资源的状态,以简化实验生命周期。在本文中,通过考虑这些问题,我们讨论了在支持OF@TEIN (OpenFlow @ Trans-Eurasian Information Network)的SDN(软件定义网络)上实现生命周期实验。为了部分地自动化生命周期实验,我们正在研究自动化的资源供应和实验执行。为了说明目前的进展,我们演示了原型生命周期实验,该实验试图将带宽测量与损坏资源节点的自动重新安装和重新配置联系起来。
Running lifecycle experiments over SDN-enabled OF@TEIN testbed
Managing the lifecycle of service-realization experiments in Future Internet testbed environments is very challenging due to the unbounded scope of user-driven experiments. The lifecycle of experiments should be carefully designed and managed among users and operators so that tasks and responsibilities are well-defined for all experiment stages. The states of involved resources should also be appropriately managed to streamline the experiment lifecycle. In this paper, by considering these issues, we discuss the realization of lifecycle experiments over SDN (Software-Defined Networking)-enabled OF@TEIN (OpenFlow @ Trans-Eurasian Information Network). In order to partially automate the lifecycle experiments, we are working on the automated resource provisioning and experiment execution. To illustrate current progress, we demonstrate prototype lifecycle experiments that attempt to link bandwidth measurements and the automated re-installation and reconfiguration of broken resource node(s).
