One network metric datastore to track them all: the OSG network metric service
/ Quick, Robert (Indiana U.) ; Babik, Marian (CERN) ; Fajardo, Edgar M (UC, San Diego) ; Gross, Kyle (Indiana U.) ; Hayashi, Soichi (Indiana U.) ; Krenz, Marina (Indiana U.) ; Lee, Thomas (Indiana U.) ; McKee, Shawn (Michigan U.) ; Pipes, Christopher (Indiana U.) ; Teige, Scott (Indiana U.)
The Open Science Grid (OSG) relies upon the network as a critical part of the distributed infrastructures it enables. In 2012, OSG added a new focus area in networking with a goal of becoming the primary source of network information for its members and collaborators. [...]

Deployment of a WLCG network monitoring infrastructure based on the perfSONAR-PS technology
/ Campana, S (CERN) ; Brown, A ; Bonacorsi, D ; Capone, V ; Girolamo, D De ; Casani, A F ; Flix, J ; Forti, A ; Gable, I ; Gutsche, O et al.
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.

Integrating network and transfer metrics to optimize transfer efficiency and experiment workflows
/ McKee, S (Michigan U., MCTP) ; Babik, M (CERN) ; Campana, S (CERN) ; Girolamo, A Di (CERN) ; Wildish, T (CERN) ; Closier, J (CERN) ; Roiser, S (CERN) ; Grigoras, C (CERN) ; Vukotic, I (CERN) ; Salichos, M (CERN) et al.
The Worldwide LHC Computing Grid relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any network issues, including connection failures, congestion, traffic routing, etc. The WLCG Network and Transfer Metrics project aims to integrate and combine all network-related monitoring data collected by the WLCG infrastructure.

WLCG Networks: Update on Monitoring and Analytics
/ Babik, Marian (CERN) ; McKee, Shawn (Michigan U.) ; Andrade, Pedro (CERN) ; Bockelman, Brian Paul (Inst. Adv. Stud. SPES, Madison) ; Gardner, Robert (Chicago U., EFI) ; Fajardo Hernandez, Edgar Mauricio (UC, San Diego) ; Martelli, Edoardo (CERN) ; Vukotic, Ilija (Chicago U., EFI) ; Weitzel, Derek (Nebraska U.) ; Zvada, Marian (Nebraska U.)
WLCG relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any network issues including connection failures, congestion and traffic routing. The OSG Networking Area, in partnership with WLCG, is focused on being the primary source of networking information for its partners and constituents. [...]

Monitoring the US ATLAS Network Infrastructure with perfSONAR-PS
/ McKee, S (University of Michigan) ; Lake, A (Lawrence Berkeley National Lab) ; Laurens, P (Michigan State University) ; Severini, H (Oklahoma University) ; Wlodek, T (Brookhaven National Lab) ; Wolff, S (Internet2) ; Zurawski, J (Internet2)
We will present our motivations for deploying and using the perfSONAR-PS Performance Toolkit at ATLAS sites in the United States and describe our experience in using it. This software creates a dedicated monitoring server, capable of collecting and performing a wide range of passive and active network measurements. [...]
