An optical ring network for fixed length messages from a plurality of nodes for transmission to different nodes uses a plurality of wavelengths for transmission, and messages for transmission are ordered and arranged on a per-wavelength basis to minimize a transmit finish time. Each node may be operated in an ADM (add drop multiplexer) mode where an optical node removes information on a particular wavelength and adds information on the same particular wavelength, or each node may be operated in a CDC (colorless, directionless, contentionless) mode where information is assigned to a wavelength according to a selection algorithm which may place it on any wavelength without regard to an original node wavelength. The selection algorithm optimizes selection of messages and wavelengths for transmit finish time. |
