Dynamic Experience Management (DEM) is a feature of AA software that monitors user plane traffic to build a network-wide view of congestion at the subscriber or ANL levels. This enables real-time dynamic actions, such as rate limiting and application blocking. It provides the optimum user experience within the actual, overall network capabilities.
In situations of high network load and congestion, the subscriber quality of experience (QoE) degrades because of restricted resources across the network (such as in the radio transport layers). In this context, background traffic and real-time traffic cannot be differentiated efficiently and dynamically. The ability to differentiate background traffic from real-time traffic is important for delay-sensitive applications, such as video.
The following implementations of the DEM gateway are available, depending on the network access deployment:
Wireless LAN DEM (WLAN-DEM) for WIFI wireless LAN gateway deployment
Non-Location Based DEM (NLB-DEM) for any access network
