A new optical label scheme called Common optical SCM (Subcarrier Multiplexing) label method is proposed. The label paths are consisting of multiplex SCM paths with SCM/WDM technology, which separate from the data wavelength paths. These label paths are parallel and shared for any data wavelength path. We analyzed the modulation and transmission of SCM label channels and compared the bandwidth efficiency and switching performance of main several optical label schemes. The results show that because of no guard between label and data packets the bandwidth efficiency increases and the operation complexity decreases in common optical label schemes and multiple shared parallel SCM label channels can decrease the block probability of label packets.
