  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. It was established to ensure sites and experiments can better
understand and fix networking issues, while providing an analytics platform
that aggregates network monitoring data with higher level workload and data
trans-fer services. This has been facilitated by the global network of the
perfSONAR instances that have been commissioned and are operated in
collaboration with WLCG Network Throughput Working Group. An additional
important updateis the inclusion of the newly funded NSF project SAND (Service
Analytics and Network Diagnosis) which is focusing on network analytics. This
paper describes the current state of the network measurement and analytics
platform and summarizes the activities taken by the working group and our
collaborators. This includes the progress being made in providing higher level
analytics,alerting and alarming from the rich set of network metrics we are
gathering.
