Description
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 constituents. We will report on the changes and updates that have
occurred since the last HEPiX meeting.
The WLCG Network Throughput working group was established to ensure sites and experiments can better understand and fix networking issues. In addition,
it aims to integrate and combine all network-related monitoring data collected by the OSG/WLCG infrastructure from both network and transfer systems.
This has been facilitated by the already existing network of the perfSONAR instances that is being commissioned to operate in full production.
We will provide a status update on the LHCOPN/LHCONE perfSONAR infrastructure as well as cover recent changes in the higher level services due to reorganisation of the OSG. This will include details on the central service migrations, updates to the dashboards; updates and changes to the Web-based mesh configuration system and details on the newly established pipeline for processing perfSONAR results.
In addition, we will provide an overview of the recent major network incidents that were investigated with the help of perfSONAR infrastructure and provide
information on changes that will be included in the next perfSONAR Toolkit version 4.1. We will also cover the status of our WLCG/OSG deployment
and provide some information on our future plans.
