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 is a partner of the WLCG effort and is focused on being the primary source of networking information for its partners and...
As the scale and complexity of the current HEP network grows rapidly, new technologies and platforms are being introduced that greatly extend the capabilities of today’s networks. With many of these technologies becoming available, it’s important to understand how we can design, test and develop systems that could enter existing production workflows while at the same time changing something as...
The transition of WLCG central and storage services to dual-stack IPv4/IPv6 has gone well, thus enabling the use of IPv6-only CPU resources as agreed by the WLCG Management Board. More and more WLCG data transfers now take place over IPv6. The dual-stack deployment does however result in a networking environment which is much more complex than when using just IPv6. During the last year the...
We will report on recent activities on integrating Federated Identity Management at the Scientific Data & Computing Center (SDCC).
