QoE validation of a RSVP protocol extension enabling efficient resource reservation for aggregated traffic in heterogeneous IP networks

In this paper we propose an extension to RSVP protocol, based on dynamic resource reservations, which allows for better coexistence of HD video transmission and elastic traffic (e.g. bulk data transfer). These extensions have been evaluated in two different domains, both in the Quality of Experience (QoE) domain and in the Quality of Service (QoS) domain. Experiments carried out in an emulated multi-node heterogeneous network show that the proposed extensions are profitable, especially in the network domain. They are able to assure a better quality of service for elastic traffic than typical RSVP reservations and offer the same QoS for HD video transmission as well-dimensioned typical RSVP. Analysis in QoE domain confirms that proposed extensions assure a video transmission quality unnoticeably worse than the one possible with RSVP (with no extensions).
