Collaborative Research: Workshop on perfSONAR based Multi-domain Network Performance Measurement and Monitoring

perfSONAR（http：www.perfsonar.net）是一组社区开发的协议和广泛采用的用于多域网络性能监控的基础设施，促进了收集和共享与解决端到端网络性能问题相关的测量数据的能力，并实现了网络感知应用。 第一次perfSONAR研讨会于2010年7月8-9日在弗吉尼亚州阿灵顿成功举行。 该项目将组织并举办第二次perfSONAR研讨会，将于2014年2月20日至21日在弗吉尼亚州阿灵顿的NSF举行，向perfSONAR社区成员开放。第二次研讨会的目标是在第一次研讨会成果的基础上，利用perfSONAR协议和基础设施固有的灵活多域特性。研讨会的重点是交流来自不同利益相关者的想法，包括：研究人员、应用开发人员、网络运营商、网络管理人员以及其他对网络研究和性能测量/监控感兴趣的人。研讨会的目标包括： 1.识别未实现的技术和网络研究的重点领域与现有的想法，可以帮助解决问题的R E网络，以及开放的研究问题，重点解决真实的世界端到端的性能问题; 2.识别网络运营商、最终用户、网络研究人员和虚拟组织所需的perfSONAR基础设施组件，以及任何缺失的组件; 3.端到端、跨域和跨洋链路的持续和按需测量的操作要求、联盟政策和最佳实践; 4.创建一个由研讨会参与者播种的更大的perfSONAR社区，包括吸引新网络研究人员，新领域科学研究人员，新科学社区和新网络的策略。 它是高性能计算社区中网络诊断的关键工具。 因此，对perfSONAR框架的增强对广泛学科的项目有直接影响。 研讨会的成果将是一份适合在ACM数字图书馆存档的报告。该报告将根据上述讲习班目标总结与会者的讨论和建议，并可为今后的社区行动提供信息和指导。

perfSONAR (http://www.perfsonar.net) is a set of community-developed protocols and a widely-adopted infrastructure for multi-domain network performance monitoring, facilitating the ability to collect and share measurement data relevant to solve end-to-end network performance problems and to enable network-aware applications. The first perfSONAR workshop was successfully held 8-9 July 2010 in Arlington, VA. This project will organize and hold the Second perfSONAR workshop to be held February 20-21 2014 at at the NSF in Arlington VA, open to members of the perfSONAR community. The goal of the second workshop is to build upon the first workshop outcomes and capitalize on the inherent flexible multi-domain nature of the perfSONAR protocols and infrastructure. The intended focus is to cross-fertilize ideas from a variety of stakeholders that include: researchers, applications developers, network operators, network managers, and others with an interest in network research and performance measurement/monitoring.The workshop goals include: 1. Identification of unimplemented techniques and network research focus areas with existing ideas that can help solve problems of R&E networks, as well as open research questions focused on solving real world end-to-end performance problems; 2. Identification of required perfSONAR infrastructure components for network operators, end users, network researchers, and virtual organizations, and any missing components; 3. Operational requirements, federation policies and best practices for ongoing and on-demand measurements end-to-end, cross-domain, and transoceanic links; and 4. Creating a larger perfSONAR community seeded by the workshop participants, including strategies for engaging new network researchers, new domain science researchers, new science communities, and new networks.perfSONAR is a tool supporting multiple high-priority programs in multiple U.S. agencies. It is a key tool for network diagnostics for in the High Performance Computing community. As such enhancements to the perfSONAR framework have direct impacts on projects across a wide range of disciplines. The output of the workshop will be a report suitable for archival within the ACM Digital Library. The report will summarize the discussions and recommendations of participants in accordance with the aforementioned workshop goals, and could serve to inform and guide future community actions.
