WLCG基础设施从基于MONARC模型的非常严格的网络拓扑结构转变为更宽松的系统，其中区域或国家之间的数据移动不一定需要涉及T1中心。虽然这一发展带来了明显的优势，特别是在LHC实验数据管理系统的灵活性方面，但它也提出了如何监控越来越多的可能网络路径的问题，以便提供全球可靠的网络服务。perfSONAR网络监控系统已被评估并被认为是涵盖WLCG网络监控用例的适当解决方案：它允许WLCG通过中央调度配置来计划和执行任何仪表化端点之间的延迟和带宽测试，它允许在本地数据库中存档度量，它提供暴露测试结果的编程和基于Web的界面;它还为远程管理操作提供了图形界面。在这篇文章中，我们将介绍我们在WLCG运营协调计划范围内部署基于perfSONAR的网络监控基础设施的活动：我们将推动我们在配置和管理方面达成一致的主要选择，描述我们开发的补充标准包的其他工具，并介绍部署状态以及未来可能的发展。
The WLCG infrastructure moved from a very rigid network topology, based on the MONARC model, to a more relaxed system, where data movement between regions or countries does not necessarily need to involve T1 centres. While this evolution brought obvious advantages, especially in terms of flexibility for the LHC experiment's data management systems, it also opened the question of how to monitor the increasing number of possible network paths, in order to provide a global reliable network service. The perfSONAR network monitoring system has been evaluated and agreed as a proper solution to cover the WLCG network monitoring use cases: it allows WLCG to plan and execute latency and bandwidth tests between any instrumented endpoint through a central scheduling configuration, it allows archiving of the metrics in a local database, it provides a programmatic and a web based interface exposing the tests results; it also provides a graphical interface for remote management operations. In this contribution we will present our activity to deploy a perfSONAR based network monitoring infrastructure, in the scope of the WLCG Operations Coordination initiative: we will motivate the main choices we agreed in terms of configuration and management, describe the additional tools we developed to complement the standard packages and present the status of the deployment, together with the possible future evolution.
