Resource Allocations Protocols Impact on MPEG Sequence Quality [chapter]

Slim Gara, Guy Pujolle
1998 Performance and Management of Complex Communication Networks  
The ITU and ATM-Forum have defined ATM transfer capabilities in order to transport a wide variety of traffic classes. The impact of A TM contracts on the quality of a MPEG sequence is investigated.  ...  MPEG-2 video compression is the standard retained for video applications. Two encoding schemes are defined: open-loop and closed-loop.  ...  In order to reduce the size of an image by 53 bytes, we increased by one the quantization parameter. Our objective is to compare the impact of ABT and rt-VBR contracts on the same video traffic.  ...

An Emergency Token Based Multiple Access Control Scheme for Wireless ATM Networks [chapter]

Kun Pang, Zhisheng Niu, Junli Zheng, Xuedao Gu

Simulations are done to evaluate its performance. We found that the scheduling scheme proposed can significantly improve rtVBR's loss and delay performance while low signalling overhead is needed.  ...  Emergency token buffer has higher priority over those of VBR and ABR. The emergency token scheduling scheme (ETSS) based on polling of token buffer is effective and easy to implement.  ...  =1 (5) As for the loss probability of nrt-VBR traffic, however, it depends not only on the system state but on the parameters of both MPEG and nrt-VBR traffic.  ...

We quantify the relationship between the time scale in the correlation of video traffic and the queue buildup using a set of experiments with traces of MPEG/JPEG-compressed video.  ...  While researchers agree on the importance of traffic correlation, there is no agreement on how much correlation should be incorporated into a traffic model for performance estimation and dimensioning of  ...  One of the authors, H. Ahn, would like to thank J. Scherer for her invaluable discussion on the manuscript.  ...

Design and analysis of a bandwidth management framework for ATM-based broadband ISDN

K. Liu, D.W. Petr, V.S. Frost, H. Zhu, C. Braun, W.L. Edwards
1997 IEEE Communications Magazine  
When designing and configuring an ATM-based B-ISDN, it remains difficult to guarantee the Quality of Service (QoS) for different service classes, while still allowing enough statistical sharing of bandwidth  ...  However, the statistical bandwidth sharing means the network resource should be occupied on-demand, leading to less traffic isolation and minimal resource allocation.  ...  Suppose at a certain moment, the VP is carrying ten 64kb/s CBR voice channels, one VBR MPEG video channel, and one VBR non-MPEG video channel.  ...
