SYSTEMS AND METHODS FOR MEDIA SERVICE DELIVERY
Methods and systems for delivering multimedia content in various telecommunications networks while optimizing quality of experience (QoE). The described methods and systems implement a fast processing path and a slow processing path. In the fast processing path, minimal packet processing is performed to reduce latency. In the slow processing path, increased packet processing is performed to identify media sessions and to perform further data processing. The slow processing path can be used in an online or offline mode, depending on a current flow state.
