Quality-of-experience (QoE) of interactive applications transmitted over TCP/IP networks has recently gained considerable attention, and is mainly influenced by transmission delays due to TCP/IP’s retransmission characteristic. This thesis shows that interactive Internet applications share the commonality of a recurring request- response cycle that is highly vulnerable to such transmission delays. In the context of two prototypical services, interactive Internet telephony and browser based applica- tions, the impact of transmission delays on QoE is analysed. In terms of interactive Internet telephony, a surface structure analysis of delay impaired voice calls reveals several changes in conversation behaviour caused by the delay. From this analy- sis, two conversational metrics are derived that capture the influence of delay on ... toggle 6 keywords
