All-Optical Packet Switching Network based on Optical Code Processing

This work introduces a significant improvement for optical packet switching network based on OC processing. The key point of this method is the generalization of the optical label switching concept to forward optical packet without label swapping and O/E/O procedure. Our proposed method simplifies the design of switch devices in optical domain and packet forwarding process which speeds up packet forwarding and increases throughput significantly. As label swapping is eliminated in this method, the upper layer (label switching layer) can operate on optical networks transparently. Key-Words: optical packet switching, optical label switching, optical code, MPLS.
