19. A management system comprising:
a network interface connected to terminal equipment from at least two users and a line system, the terminal equipment from the at least two users and the line system forming an optical line system;
one or more processors communicatively coupled to the network interface; and
memory storing instructions that, when executed, cause the one or more processors to
for at least one fiber having optical spectrum being shared by the at least two users in the optical line system, assign value to the optical spectrum using spectral efficiency of the optical spectrum, wherein the assigned value is dependent on Generalized Signal to Noise Ratio (GSNR) and varies over time as performance of the optical spectrum changes over time,
determine using a policy and the assigned value of the optical spectrum how to partition the optical spectrum between the at least two users, wherein the assigned value is a metric used to determine the partition based on the policy, and
cause implementation of the partition of the optical spectrum.
