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

PerformSONAR(http://www.perfsonar.net)是一套社区开发的协议和广泛采用的基础设施，用于多域网络性能监控，促进收集和共享与解决端到端网络性能问题和支持网络感知应用相关的测量数据的能力。第一次PerformSONAR研讨会于2010年7月8日至9日在弗吉尼亚州阿灵顿成功举行。该项目将于2014年2月20日至21日在弗吉尼亚州阿灵顿的国家科学基金会组织并举办第二届PerfSONAR研讨会，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再接再厉，并利用PerSONAR协议和基础设施固有的灵活多域性质。研讨会的重点是将各种利益相关者的想法相互融合，这些利益相关者包括：研究人员、应用程序开发人员、网络运营商、网络经理和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.确定未实施的技术和网络研究的重点领域，以及可以帮助解决R&A；E网络问题的现有想法，以及关注解决现实世界端到端性能问题的开放研究问题；2.确定网络运营商、最终用户、网络研究人员和虚拟组织所需的Performance SONAR基础设施组件，以及任何缺失的组件；3.持续和按需测量端到端、跨域和跨洋链路的操作要求、联盟政策和最佳实践；以及4.创建由研讨会参与者播种的更大的PerformSONAR社区，包括吸引新的网络研究人员、新的领域科学研究人员、新的科学社区和新的网络的战略。PerformSONAR是一个支持多个美国机构的多个高优先级计划的工具。它是高性能计算社区中用于网络诊断的关键工具。因此，对PersSONAR框架的增强对跨广泛学科的项目具有直接影响。讲习班的成果将是一份适合在ACM数字图书馆内存档的报告。该报告将总结与会者根据上述讲习班目标进行的讨论和提出的建议，并可作为今后社区行动的参考和指导。

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.
