Abstract

Wavelength conversion (WC) is highly useful for contention resolution in optical packet switches (OPS). However, the immature technology and the high cost of full‐range tunable‐wavelength converters (FTWCs) remain big challenges. We propose a new scheme in OPS where fixed‐wavelength converters (FWCs) instead of FTWCs are used in contention resolution. This scheme is cost‐effective and easier to implement. The performance of the FWC is compared with that of the FTWC. Our simulation results under different scenarios clearly show that the new scheme can achieve a performance comparable to that of the FTWC case, at significantly lower complexity and cost. © 2004 Wiley Periodicals, Inc.

## Abstract We experimentally demonstrate an optical packet routing node with contention resolution in the time and wavelength contention domain. The node comprises an optical buffer and a wavelength converter. Although the experimental results are shown at 10 Gb/s, the bitrate can be increased sub

## Abstract Contention resolution techniques greatly affect the architecture and performance of an optical packet switch (OPS). Fiber delay lines (FDLs) and wavelength converters which can resolve the contention problem and provide acceptable performance, have been demonstrated in many OPS designs.

## Abstract In this paper, we propose a new contention‐resolution scheme for supporting time‐critical applications in multifiber optical packet‐switched networks. The main idea is to utilize redundant idle fibers in optical cables rather than the conventional optical‐fiber delay lines to transfer t
