There are many non-technical and equally important aspects associated with the global multimedia conferencing. Some of these are social, business, cultural, and environmental. The article touches on a few inter-related dimensions of multimedia conferencing as a viable future of global communication and directly relate both to this particular service in how and what is really involved. The ATM traffic optimising manager (ATOM) offers an effective generalised solution to the mixed sources of traffic characterised as real-time, flexible-time, CBR and VBR. In this method we use a specially configured common buffer for interfacing, controlling and serving the ATM cells by applying accurate accounts for each service for their quality using a simplified method of the traffic associated grading (TAG) mechanism. The TAG mechanism provides a solution in enabling the technology to accommodate and control mixed traffic based upon their quality characteristics. It is essentially a trade-off to various parameters in the services involved seeking an ultimate satisfactory working condition which in turn improves the system's overall optimum performance. The sample results provided shows how the delay and loss are swapped by the parameters of the TAG as the main controller of the drop and delay decision. (5 pages)
