Quality of Experience assessment for network monitoring

The number of existing applications on Internet increases more and more. Their traffic characteristics and performance requirements are very different and evolve in time, and the users have diverse behaviours with these applications. An Internet Service Provider needs to satisfy the customers' requirements in spite of these heterogeneities. The Quality of Experience (QoE) seems a promising tool to manage a network taking into account this diversity. Classical methods to correlate this QoE from network performance criteria are based on long and expensive experiments with a panel of users. We propose then a fast and cheap method to assess up-to-date QoE by application from a passive traffic analysis.
