The invention relates to one improved method and System for implementing submultiplex segment sharing protect in all-optical network, specially, relates to method and System for implementing traffic protect through sharing sub-multiplex segment in all-optical network by adopting dense wavelength division multiplexing (DWDM) technique. The invention determines the numbers of sub-multiplex segments into which are divided by System wavelength according to actual distribution condition of protected traffic nd non-protected traffic in network. The System at least includes a wave synthesizer at two sides of node, a wave separator at two sides of node, and optical protecting module. The invention can accomplish a sub-multiplex protecting function of optical layer, can satisfy multiple accessing traffic requirement, can improve availability of system capacity in this case of satisfying partial traffic protection, can optimize using system resource, and has strong practicability, can reduce the system cost at same time. |
