Abstract
A general overview of interconnection networks is given. The delta network is chosen for the switch fabric of a Broad band ISDN ATM switch. Architectural options for the switching elements of a delta network are identified. Formulas are developed which analyze the throughput and delay performance of delta networks composed of switching elements based on these architectures. The formulas are more general than those found in the literature. Simulations are performed to validate the analysis.
The optimum switching element architecture is chosen. A design is given for a 25 MHz CMOS 2 x 2 switching element capable of hand ling proposed Broadband ISDN data. rates of 155.520 Mbits/sec. Data.paths throughout the switching eleĀment are nine bits wide, including a parity bit. With virtual cut-through enabled, a packet may exit a switching element as early as three clock cycles after entering the switching element.
