100 Gigabit Ethernet is an emerging technology and to support it, existing switch fabrics need to be redesigned. High throughput and QoS are required. A scalable multi-stage fabric based on a Clos architecture is envisaged to meet these demands. Using OPNET modeler, a design based on a variation of such an architecture is implemented and evaluated. The model has three switch stages with buffers in the middle stage and last stage. It offers different kinds of forwarding schemes in the first stage, like Desynchronized Static Round-Robin, Random and Static schemes. Traffic types include uniform, unbalanced and trans-diagonal patterns, as well as self-similar traffic obtained from ON/OFF Pareto distributed processes.
