Abstract :
In this paper, we construct a composite label sets for optical multi-protocol label switching (MPLS) network. Relatively prime lengths maximal-length (M-sequence) codes are taken to compose into spectral-amplitude coding (SAC) labels. These composite M-labels possess good orthogonality and are compatible with packet labels stacking. With correlation subtraction scheme in packet routing node, local node label can be identified from the stacked labels. The composite M-labels are coded with arrayed-waveguide gratings (AWGs) with small number of input-output ports to reduce hardware requirement. Compared with conventional M-sequence labels, composite M-labels behave more flexibility on routing data packets. The proposed composite M-labels coding can support optical packet switching network (OPS) with fast label processing.
