📄️ Unidirectional flow
A unidirectional flow records network traffic in a single direction, from source to destination, commonly generated by flow export technologies like NetFlow and IPFIX.
📄️ Upstream vs downstream traffic
Upstream traffic flows from a user, subscriber, or local network toward the wider network, while downstream traffic flows toward the user or subscriber. Analyzing traffic direction helps operators understand bandwidth consumption, traffic asymmetry, application behavior, and network capacity requirements.
📄️ Uptime monitoring
Uptime monitoring is the process of continuously checking whether a service, application, device, or network resource is available and responding as expected. It helps operators detect outages, measure availability, and support service-level objectives.
📄️ User analytics
User analytics is the analysis of user activity, behavior, access patterns, and resource usage to understand how individuals or groups interact with applications, services, and network resources. It helps organizations associate activity with specific users and identify behavioral, operational, and security-related insights.
📄️ User behavior analysis
User behavior analysis (UBA) is the process of examining user activity patterns over time to understand normal behavior, identify anomalies, and support operational or security investigations.
