All-optical label swapping (AOLS) is a promising approach of implementing label swapping techniques for transparent optical packet switching and forwarding in the optical layer at high-speeds close to fiber line-rates. In this paper, an AOLS-based all-optical packet switch node architecture for WDM simultaneous all-optical time-serial label processing is presented. The AOLS technologies based on all-optical logic gates enable the switch to process optical data packets at 40 Gb/s directly in the optical domain, independent of the payload bitrate and length. Two all-optical label swapper designs of this switch are discussed. Furthermore, contention resolution for this AOLS packet switch is also addressed. © 2005 IEEE.
