IETF Draft: Device-based Real-time Video QoE Improvement

A new IETF draft by Bhumip Khasnabish (pictured) and Gerard Fernando both from ZTE (US) suggest how to improve video QoE without network intervention.  


"This draft describes a method for improving the quality of experience (QoE) for real-time video and other multimedia services using features and functions of the end-point only, that is, without requiring any upgrade to the network transport infrastructure. Any upgrade to the network transport infrastructure not only incurs significant costs, these are also time consuming and technology- dependent. Therefore, these QoE improvement mechanisms are significantly more attractive to both network operators and service providers".

"This document defines a common set of QoE parameters that are applicable for HTTP, Websocket or RTP sessions .. In order to improve quality it is common practice to focus on improving network infrastructure (bandwidth increase, etc.). However, our proposal enables improvements in quality by utilizing transport independent QoE management".
