Abstract

Multi-protocol label switching (MPLS) has the advantage of high efficiency in the second layer, which improves the performance of data packets routing. In this paper, a new structure to implement optical MPLS is proposed. We construct a code family for spectral-amplitude coding (SAC) labels in the optical MPLS networks. SAC labels are suitable for optical packet switching because they can be constructed and recognized quickly at each router. We use the label stacking to provide hierarchical routing to avoid swapping labels at each forwarding node and reduce system complexity. However, the phase-induced intensity noise (PIIN) appears due to the incoherent property of the light source when the stacked labels set makes the correlation decoding with the local node label, which degrades system performance.
