The Monitoring Services PICs support Juniper Networks J-Flow accounting at high speeds and across millions of flows. This dramatically increases performance and scalability when contrasted with the routing engine based flow-monitoring capability. Service providers now have a scalable solution to monitor traffic flows in real time, collecting and exporting per-flow statistics in standards-based cflowd v5 and v8 records. This flow data can be used to provide granular accounting for billing, to analyze traffic patterns for network planning, and to perform security analysis.
