N2 - The interface data rates to the external lines (i.e., line card data rates) can be and usually are different from the internal core fabric speed of an ATM switch. As signals are multiplexed inside the switch to higher speeds, the required dimension of the core fabric is reduced, leading to a reduction in physical size, easing of input/output (I/O) constraints, simpler control, and improved hardware efficiency. Our simulation results, for random and bursty traffic models, indicate that this hierarchical multiplexing technique has little impact on the delay-throughput performance. Our results also show that a small degree of multiplexing dramatically increases the buffer requirements. However, further multiplexing reduces the amount of buffering down to more acceptable levels.
