广域大规模实验平台设计和研究

Design and Research of Wide-Aera Large-Scale Internet Testbed

针对互联网实验床的特点,本文分析了传统互联网实验床的成功经验和不足,基于可扩展、可隔离和真实性三个基本原则,设计了一个新的广域大规模实验平台。该平台基于层次性结构,不同区域的节点设备形成自治的设备集群,每个集群通过管理节点进行管理和互联,接受中心管理器的统一管理。实验平台通过VLAN为实验提供隔离的网络环境,基于虚拟化技术为实验提供隔离的资源,并提供持久数据存储空间方便实验存储和共享数据。

According to the characteristics of Internet testbed, this paper analyzed the successful experience and the insufficiency of traditional Internet testbeds. Based on the three principles, extensible, isolable,o and real, a new widearea largescale Internet testbed was designed. In this layered testbed, devices in different regions form autonomous clusters. Each cluster is managed and connected with each other by a management node. There exists a center manager which manage all the clusters. The testbed provides isolated network environment through VLAN, and isolated physical resources through virtualization. Besides, persistent storage space is provided for tests to store and share datas.
