To succeed in providing services, the quality of services should meet users' satisfaction.This is a motivation to study the relationship between the service quality and the real perceived quality of users, which is commonly referred to as the quality of experience (QoE).However, most of existing QoE studies that focus on video-on-demand or IPTV services analyze only the influence of network behaviors to video quality.This paper focuses on P2P video streaming services, which are becoming a significant portion of Internet traffic, and pays attention to the change of users' perception with the adjustment of objective factors as well as network behaviors.We propose to use mean opinion score and peak signal to noise ratio methods as QoE evaluations to consider the effect of the chunk loss ratio, the group-of-picture size, and the chunk size.The experimental results provide a convincing reference to build the complete relationship between objective factors and QoE.We believe that this assessment will contribute to study a new service quality evaluation mechanism based on users' satisfaction in the future.
