Hi, I am greatly interested in doing some work on Long Range Dependence of ATM traffic modeling. I have several questions as follows. 1. Single VBR video source traffic is considered as LRD traffic. What are the characteristics of multiplexing traffic of multiple sources, (e.g., does the output traffic of an ATM multiplexer have the property of LRD?). 2. Since Internet traffic (i.e., LAN/WAN) is partly considered as LRD traffic, what impact does it have on design of Bridge/Router? 3. Where can I find Video traffic database (e.g., film compressed by Mpeg-2)? 4. Are there any mail groups discussing LRD and/or ATM? Thanks, Zhang Peng
