....resulting in a decreased playable frame rate. A series of traces from a previous Internet measurement study [9] were used to simulate the e ects of bursty loss over a range of loss conditions. For each loss event, we used the probability distribution obtained from Internet streaming traces in [21] and depicted in Figure 7a, to provide bursty loss events. a.

The possible impact of bursty losses is that Section 2.2, it becomes less likely that K packets of the N total frame packets can be recovered, resulting in a decreased playable frame rate. A series of traces from a previous Internet measurement study [9] were used to simulate the e ects of ....

....the stream is sent to the player) For RTCP, feedback is limited to network level metrics, such as network level packet loss. The approach we propose is to utilize existing client side players in the assessment of streaming media quality via observations at the client. Previous work, such as [18, 19] has addressed this as well, although the solutions derived either require user intervention ( 18] or entirely new media player applications ( 19] We propose a method that does not entail the modification of the client side media player application and that is completely transparent to the ....

III. METHODOLOGY In this section, we present our proposed methodology for streaming media quality assessment. We begin by discussing indicators ....

....server popularity, and sharing patterns of streaming media among the clients. As the the number of internet users continues to grow, and as the high speed access methods become more ubiquitous, streaming media starts to occupy more sizable fraction of the Internet s bandwidth. Few recent papers [15,14,18] analyze the impact of streaming media on the Internet traffic and the performance of popular Internet real time streaming technologies. Our paper builds upon this previous work in a number of significantways. To our knowledge, this paper is the first study of enterprise media server workloads. ....

Also, they uncovered a high degree of user interactivity in the workload, which implied that the effectiveness of multicast delivery is limited. Streaming Traffic Characterization: Several studies [21] 10] [20], 29] have focused on low level dynamics of streaming access, such as packet loss and delay, network transport protocols. Mena and Heidemann [21] examined the traffic emanating from a popular Internet audio service using the RealAudio program. They found a pervasive use of non TCP friendly ....

....protocols, and strong consistencies in audio traffic packet sizes and data rate patterns. Recently, based on this study, Lan and Heidemann [10] identified the structural properties of RealAudio traffic, and developed and validated an application level simulation model. Loguinov and Radha [20] analyzed several network performance metrics including packet loss, round trip delay, one way delay jitter, packet reordering, and path asymmetry. In particular, their findings suggest that Internet packet loss is bursty. Both the distributions of loss burst length and round trip time appear to ....
