Abstract
| WLCG experiments rely on networks as one of the critical components of their infrastructure. These networks are used to interconnect participating sites, data centres, and scientific instruments both within the laboratories and globally. Network traffic used by WLCG experiments is split across purpose-built networks such as LHCOPN and LHCONE as well as the research and education networks (R&E; networks) operated by campuses, research organisations and national research and education network providers (N/RENs). These networks are becoming increasingly complex due to the increase in the number of science projects, total amount of data transferred and the divergent variables that govern these projects (requirements, configuration, etc.). One of the key challenges in this complex environment is improving our ability to see which experiments are creating network flows. |
