QoE-driven traffic management gives service providers the necessary control to set and manage a QoE target for individual media sessions or across multiple media sessions. QoE traffic management abstracts the complexity of video service management for the service provider and focusses the service delivery on the user’s perceived experience. This greatly simplifies the process of designing and managing complex policy rules in order to achieve business goals for video service delivery, by allowing the service provider to specify the target QoE level for any given media session in a common relative service delivery metric.
QoE-driven traffic management is a key capability of the XperiumOS video traffic management function. XperiumOS implements dynamic video quality prediction and adjustment towards a target QoE level using deep media session inspection that dynamically determines real-time QoE of source content throughout the media session. XperiumOS actively monitors and adjusts the encoding parameters throughout the session to maintain the target QoE level and ensure the session meets the selected target.
XperiumOS QoE-driven traffic management can also operate in an aggregate management mode. This permits QoE normalization, for fair-sharing of network resources, which delivers the majority of users the best experience possible given the active video sessions and network capabilities. This protects against unequal assignment of network resources, where a minority of users consume the majority of the network resources. This also permits QoE differentiation for video service plans to be created such that tiers of quality can be established between different service provider offerings.
The figure below illustrates the broad range of quality targets and bitrate savings that can be achieved when XperiumOS QoE-driven traffic management is combined with XperiumOS Adaptive Stream Management.
