Abstract: Passive monitoring of user-perceived performance degradation is an important tool for service providers to improve customer loyalty. In this paper, we discuss our on-going work on the development of two network-based methods to objectively assess the user-perceived network performance. One method is based on the observation of TCP connections interrupted by the users. This method allows us to detect user’s interest in the service in relation to the network performance. Another method is simple and based on the identification of traffic gaps in the user transfers that may hurt the user perception. This work, amongst others, provokes a discussion on the impact of the frequency and duration of such gaps.
