Abstract — The experienced quality of services such as IPTV, video on demand, online gaming and VoIP is very sensitive to packet loss, delay and jitter. Therefore it is an essential requirement that access network providers are able to monitor and control with rather high resolution the end-to-end service delivery paths. Because this task is very complicated we are developing an autonomic framework for quality of experience (QoE) management. A two layer architecture is proposed, consisting of a monitor plane and a knowledge plane. The first is responsible for providing the available monitor information, the latter uses that information to determine the location and cause of a QoE problem and determines a fitting solution. The first step in autonomicly managing service QoE is detecting when a problem occurs. In this paper we introduce ANTMA, the Access Node TCP Monitoring Algorithm. It monitors TCP connections by analyzing the packets that pass an intermediate point, such as an access network element or a residential gateway, thereby allowing fault isolation. We provide a detailed analysis of how ANTMA works and also present a thorough evaluation of its behavior. The algorithm is an essential component in enabling autonomic QoE management. I.
