摘要： 传统网络实验平台通过直接物理设施或层叠网构建，但这类构建方案无法同时保障较高的物理资源利用率和实验网络链路质量。为此，提出一种基于云计算平台和虚拟化技术的网络创新实验平台设计方案，并给出其原型系统TUNIE的实现。应用结果表明，TUNIE在设计实现上能兼顾功能支持的灵活性与使用的便捷性，而且提供高性能的网络链路和具有良好网络隔离的多用户并发运行环境。

Abstract: In order to solve the problem that the conventional approaches for network experiment platforms, which construct an experiment platform either as a physical network directly or in the form of overlay networks, cannot guarantee a high resource utilization and a well network link quality at the same time, this paper proposes a scheme for network experiment platform based on cloud computing and virtualization technology, and provides its preliminary implementation called TUNIE. Result shows that the platform is both flexible in function support and convenience for use, as well as providing a high bandwidth connection and a well-isolated network environment for multi-user support.
