环太平洋应用程序和网格中间件大会（PRAGMA）是一个由研究人员组成的国际社区，他们积极合作，解决eScience中共同感兴趣的问题和挑战。PRAGMA实验网络测试床（PRAGMA-ENT）的建立旨在构建一个国际软件定义网络（SDN）测试床，为PRAGMA网络基础设施提供必要的网络支持。PRAGMA-ENT是一个独立的项目，PRAGMA的研究人员可以完全自由地访问网络资源来开发、实验和评估新的想法，而不必担心干扰生产网络。在第一阶段，PRAGMA-ENT的重点是建立一个国际L2骨干网。在佛罗里达Lambda Rail、Internet2、PacificWave、日本千兆网络和台湾先进研究和教育网络的支持下，PRAGMA ‐ ENT骨干网连接了佛罗里达大学、加州大学、圣地亚哥大学、奈良科学技术研究所（日本）、大坂大学（日本）、国家先进工业科学技术研究所（日本）、PRAGMA-ENT的第二阶段包括对控制平面技术的评估，该技术使多个实验（即OpenFlow控制器）能够共存。FlowVisor的初步实验揭示了一些局限性，导致了一种新方法的开发，称为AutoVFlow。本文描述了我们在建立PRAGMA ‐ ENT骨干网（具有国际L2链路）方面的经验，其现状以及控制平面的计划。讨论了初步的应用思路，包括路由控制优化，多路径路由控制，使用覆盖网络扩展骨干网和远程可视化进行了讨论。
The Pacific Rim Application and Grid Middleware Assembly (PRAGMA) is an international community of researchers that actively collaborate to address problems and challenges of common interest in eScience. The PRAGMA Experimental Network Testbed (PRAGMA‐ENT) was established with the goal of constructing an international software‐defined network (SDN) testbed to offer the necessary networking support to the PRAGMA cyberinfrastructure. PRAGMA‐ENT is isolated, and PRAGMA researchers have complete freedom to access network resources to develop, experiment, and evaluate new ideas without the concerns of interfering with production networks.In the first phase, PRAGMA‐ENT focused on establishing an international L2 backbone. With support from the Florida Lambda Rail, Internet2, PacificWave, Japan Gigabit Network, and TaiWan Advanced Research and Education Network, PRAGMA‐ENT backbone connects openflow‐enabled switches at University of Florida, University of California, San Diego, Nara Institute of Science and Technology (Japan), Osaka University (Japan), National Institute of Advanced Industrial Science and Technology (Japan), and National Applied Research Laboratories (Taiwan).The second phase of PRAGMA‐ENT consisted of an evaluation of technologies for the control plane that enables multiple experiments (ie, OpenFlow controllers) to coexist. Preliminary experiments with FlowVisor revealed some limitations leading to the development of a new approach, called AutoVFlow.This paper describes our experience in the establishment of PRAGMA‐ENT backbone (with international L2 links), its current status, and plans for the control plane. Discussion of preliminary application ideas, including optimization of routing control; multipath routing control; extending the backbone using overlay network; and remote visualization are also discussed.
