The present paper shows incorporation of an indicator for testing routing algorithms in topologically equivalent scenarios. The indicator is based on the topological disorder shown by the link matrix on its secondary diagonal, since optical networks are generally symmetric with respect to the main diagonal. In this way, comparisons can be made for scenarios with a different number of nodes, but maintaining the same topological disorder, in this way the routing algorithms can be tested with greater precision in the simulations. In general, the heuristics are compared from the operability in high traffic networks, however, no studies of the algorithm's operability are carried out while the nodal load is progressively increased while maintaining the topological complexity. This new indicator is called Topological Entropy that allows the comparison of the algorithms in conditions of topological equivalence. The results show the functioning of the methodology for different entropic states, which allows comparing different algorithms and their response time.
