Abstract
The RWA problem can be formulated as a Mixed-Integer linear program.
Load balancing is a key factor for the optical transport networks.
However, the existed approaches using mixed-Integer linear program to
solve the RWA problem are not perfect enough without considering the
load balancing of the networks.
This documentary provides a model of Mixed-Integer Linear Programming
to solve the problem of load balancing needed by routing and
wavelength assignment (RWA) process in optical transport networks.
