Analyzing, Identifying & Alerting on Network Issues
/ Vasileva, Petya (Michigan U. ; Plovdiv U.) ; Babik, Marian (CERN) ; McKee, Shawn (Michigan U.) ; Vukotic, Ilija (Chicago U.)
The Worldwide LHC Computing Grid (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. In this paper, we will describe our ongoing work to proactively analyze, correlate and alert on various network and infrastructure issues. [...]

Identifying and Understanding Scientific Network Flows
/ Research Networking Technical Working Group Collaboration
The High-Energy Physics (HEP) and Worldwide LHC Computing Grid (WLCG) communities have faced significant challenges in understanding their global network flows across the world’s research and education (R&E;) networks. This article describes the status of the work carried out to tackle this challenge by the Research Technical Networking Working Group (RNTWG) and the Scientific Network Tags (Scitags) initiative, including the evolving framework and tools, as well as our plans to improve network visibility before the next WLCG Network Data Challenge in early 2024.

Collaborative Operational Security: The future of Cybersecurity for Research and Education
/ Crooks, David (Rutherford) ; Acris, James (Rutherford) ; Atherton, Liam (Rutherford) ; Clark, Paul (Durham U.) ; Cutrina, Pau (CERN) ; Jordan, David (Chicago U.) ; McKee, Shawn (Michigan U.) ; Vâlsan, Liviu (Durham U.)
No single organisation has the resources to defend its services alone against most modern malicious actors and so we must protect ourselves as a community. In the face of determined and well-resourced attackers, we must actively collaborate in this effort across HEP and more broadly across Research and Education (R&E;).Parallel efforts are necessary to respond appropriately to this requirement.

Overcoming obstacles to IPv6 on WLCG
/ Babik, Marian (CERN) ; Bly, Martin (Rutherford) ; Buraglio, Nick (LBL, Berkeley) ; Chown, Tim (JISC) ; Christidis, Dimitrios (CERN) ; Chudoba, Jiri (Prague, Inst. Phys.) ; DeMar, Phil (Fermilab) ; Molina, José Flix (Madrid, CIEMAT) ; Grigoras, Costin (CERN) ; Hoeft, Bruno (KIT, Karlsruhe) et al.
The transition of the Worldwide Large Hadron Collider Computing Grid (WLCG) storage services to dual-stack IPv6/IPv4 is almost complete; all Tier-1 and 94% of Tier-2 storage are IPv6 enabled. While most data transfers now use IPv6, a significant number of IPv4 transfers still occur even when both endpoints support IPv6. [...]
