Optical transmission system, operational wave length several restriction methods and program

摘要

Being connected by the transmission line of the network which does the optical communication with wavelength division multiplex correspondence attaching the light information of that transmission line, to the wave length of that light information and following to the pass type which is set being the optical transmission system which transmits, when the number of operational wave lengths is modified in compliance with the change request which possesses with the acceptance section which accepts the upper limit memory section which remembers the upper limit of the number of operational wave lengths which are the number of wave lengths where pass type is set and the change request which requires the modification of the number of operational wave lengths and the license decision section which decides the number of operational wave lengths, as for the license decision section, it acceptsWhen the number of wave lengths, it is below the upper limit which is remembered, the number of wave lengths which are modified particularly is designated as the number of new operational wave lengths.
