Abstract:
Generalized multi-protocol label switching (GMPLS) is a promising technique to implement all-optical core networks. In this paper, we propose a new optical code labeling (OCL) based on optical code- division multiple access (OCDMA) techniques for packet switching. To improve the efficiency of label-recognition and network throughput, bipolar label coding is employed in the proposed scheme. Label switching capabilities in packet loss probability (PLP) is greatly enhanced since our proposal enlarges the Hamming distance of the star diagram of the decoded label signals. The proposed label mapping mechanism is achieved through spectral amplitude coding (SAC) in the physical layer. In performance analysis, we present a numerical simulation of PLP to quantify the switching efficiency. Results show the proposed bipolar coding technique reduces PLP in switching process, resulting in an extension of label switching path (LSP) in GMPLS core network.
