Enterprise networking, modeling and simulation: status and prospects for the Middle-East

This paper describes AT&T´s efforts in the area of networking with specific reference to modeling and simulation for the design of enterprise networks especially with upcoming ATM/BISDN technologies. A brief review of the tools researched and evaluated by AT&T is conducted followed by a detailed simulation example using ATM in LAN/WAN design. This is followed by a discussion of how this experience could be utilized internationally in the developing nations with specific reference to the Middle-East. This paper is supplemented with a separate tutorial on simulation and modeling in general and simulation tool usage in particular using OPNET. This is one of the leading tools that is now being widely used along with other tools within different business units at AT&T to develop professional services including enterprise networking, telecom and LAN/WAN architecture studies, network management and network operations support systems.
