Quality of Service in Ultrabroadband (UBB) Models

Abstract

In this paper we study and analyze need for Quality of Service (QoS) over the current fiber technologies and the role of the user and his Quality of Experience (QoE). We conclude that the current QoS models for multiplay services could get very complicated and the UBB technology could only simplify certain processes that are related to throughput and bandwidth. Finally we conclude that the role of the QoE is very important to assure the ultimate experience but also to help constructing cost models from the user's perspective and his needs, especially when these shift beyond his pre-agreed levels.

Keywords: ultrabroadband networks, QoS models, QoE metrics
