Authors
Abstract
The increase in multimedia content on the Internet has derived in arenewed interest in quality assessment, the difference is that now, the focus relies
on the user perceived quality, opposed to the network centered approach classically
proposed. In this paper we overview the most relevant challenges present
nowadays in order to perform Quality of Experience (QoE) assessment in IP networks.
We highlight the particular considerations necessary compared to alternative
mechanisms, already deployed, such as Quality of Service (QoS). To assist
the detection of such challenges we first discuss the different approaches to QoE
assessment along with the most relevant metrics considered in QoE, and how are
they used in order to provide objective results about user satisfaction.
