DPI for application performance and digital experience monitoring
As the number of cloud-based applications managed by enterprises continues to rise, IT-teams within enterprises must have enhanced capabilities in place for application- and network-level monitoring. These have to be accompanied by real-time alerts and timely identification of the root causes and complemented by predictive maintenance and preventive mechanisms. To achieve this, application performance monitoring (APM) tools have to go beyond simple network management protocol (SNMP) and flow-based traffic monitoring.
Deep packet inspection (DPI) technology provides the intelligence to detect performance issues delivering a converged, end-to-end view of enterprise application performance, enabling real-time analytics on enterprise network links and connectivity such as LAN and WAN, as well as on user devices and external connectivity. It also allows for a deeper dive into application layers, protocols and application attributes. Without packet-level analytics, there will be delays in diagnosing application performance issues and bottlenecks in the network. Application performance management (APM), network performance management (NPM) and digital experience management (DEM) solutions empowered with integrated DPI functionality provide enterprises the ability to understand application performance in a holistic, end-to-end manner with real-time analytics on such variables as network links and internal connectivity, as well as external connectivity and performance bottlenecks caused by user devices.
