We consider the problem of traffic grooming in wavelength-divisionmultiplexing (WDM) rings. Our objective is to minimize the required number of electronic add–drop multiplexers. We first formulate the problem as an integer linear programming (ILP) problem, and we then show that this ILP problem can be converted into an equivalent mixed ILP (MILP) problem in which a large number of integer variables in the original ILP can be relaxed to continuous variables. The resulting MILP problem is much… CONTINUE READING
