In today's world of distributed collaborations of scientists, there are many challenges to providing effective infrastructures to couple these groups of scientists with their shared computing and storage resources. The Pythia Network Diagnostic InfrasTructure (PuNDIT) project will integrate and scale research tools and create robust code suitable for operational needs to address the difficult challenge of automating the detection and location of network problems. PuNDIT will build upon the de-facto standard perfSONAR network measurement infrastructure to gather and analyze complex real-world network topologies coupled with their corresponding network metrics to identify possible signatures of network problems from a set of symptoms. For example if the symptoms suggest a router along the path has buffers configured too small for high performance, Pythia will return a diagnosis of "Small Buffer". If symptoms indicate non-congestive packet-loss for a particular network segment, the user can be notified of a possible "Bad Network Segment". A primary goal for PuNDIT is to convert complex network metrics into easily understood diagnoses in an automated way.

在当今科学家的分布合作的世界中，提供有效的基础架构面临许多挑战，使这些科学家将这些群体与他们的共享计算和存储资源相结合。 Pythia网络诊断基础架构（PUNDIT）项目将集成和扩展研究工具，并创建适合操作需求的强大代码，以应对自动化网络问题的检测和位置的艰巨挑战。 Pundit将建立在事实上的标准Perfsonar网络测量基础架构上，以收集和分析复杂的现实世界网络拓扑以及其相应的网络指标，以从一组症状中确定网络问题的可能签名。例如，如果症状表明沿路径的路由器的缓冲液配置得太小而无法进行高性能，则毕曲霉将返回“小型缓冲液”的诊断。如果症状表示特定网络细分市场的非库存数据包损失，则可以将用户通知可能的“不良网络段”。专家的主要目标是以自动化的方式将复杂的网络指标转换为易于理解的诊断。
