Statistical multiplexing of variable bit rate video sources in asynchronous transfer mode networks

Joint MPEG-2 coding for multi-program broadcasting of pre-recorded video

“…The mean of cells generated per frame, \x, and the standard deviation of cells generated per frame, a, are the two parameters used in bandwidth estimations. A statistical model, found in [13], uses the average bit-rate, the bit-rate variance, and the peak bit-rate of a video source as parameters to characterize the video source. Using simulation results, [14] shows that a VBR bit-rate video stream can be characterized using statistical measures such as the marginal distributions and the peak-to-average ratio of the bit-rates.…”

Traffic control in an ATM network using fuzzy set theory

“…In order to have an appropriate admission control, the network should have enough information about the traffic characteristics of the currently connected and newly requested users (customers). The proposed parameters for describing the source traffic characteristics are the average bit rate (,ABR), peak bit rate PBR), burstiness (=PBR/ABR) or PBR duration Several admission control methods were proposed, but the methods either assumed a too sim lified model or were too complicated to implement b, 8,91. In [8], the authors proposed an admission control scheme based on a burst model without considering the output buffer size.…”

In [8], the authors proposed an admission control scheme based on a burst model without considering the output buffer size. In this case, the relationship between the cell loss probability and the buffer size is not clear and difficulties in the implementation of the method occur when the number of call classes is large.…”
