A DASH SURVEY: THE ON-OFF TRAFFIC PROBLEM AND CONTEMPORARY SOLUTIONS


This survey explores different aspects of adaptive streaming. It first gives a history of adaptive video streaming. It is desirable for users to receive desired or adequate quality of experience (QoE), when viewing an online video. ON-OFF traffic patterns associated with competing adaptive players is then described. This is a very important area of research as it is found that poor user-perceived QoE is experienced by competing players as a result of ON-OFF traffic patterns. A set of real-world factors which affect the user-perceived QoE as a result of competing players are then investigated. After stating the problem and factors that affect adaptive streaming players, this survey paper closes with a classification of state of the art adaptive video streaming techniques, which try to remedy the problem and some of the factors.
