“…Summing up the above analysis, it is evident that the Gamma density is better for H.261 unconstrained traffic, the Loglogistic for unconstrained H.263, H.263+ traffic, and the C-LVMAX method for all cases of constrained traffic (including H.264 traffic, as proposed in [32]). However, if a generic and simple model needed to be applied for all cases then the most dominant would be the Loglogistic density.…”

is paper presents modelling results for H.26x video traffic generated by popular videoconference soware applications. e analysis of videoconference data, that were measured during realistic point-point videoconference sessions, led us to the general conclusion that the traffic can be distinguished into two categories: unconstrained and constrained. In the unconstrained traffic, there is a direct relation between the encoder and the form of the frequency histogram of the frame-size sequence. Moreover, for this type of traffic, strong correlations between successive video frames can be found. On the other hand, where bandwidth constraints are imposed during the encoding process, the generated traffic appears to exhibit similar characteristics for all the examined encoders with the very low autocorrelation values being the most notable one. On the basis of these results, this study proposes methods to calculate the parameters of a widely adopted autoregressive model for both types of traffic.

“…3 is the proportions of large (4512 bytes) and small (o512 bytes) packet sizes in the video streams. Video codec traffic modeling studies such as Kouremenos et al (2006) and Domoxoudis et al (2006) have also demonstrated comparable proportions of large and small packet sizes in the video streams generated by video codecs such as H.261, H.262, H.263 and H.264 found in popular desktop videoconferencing end-points.…”
