Methods, apparatus and articles of manufacture (e.g., physical storage media) to perform service specific route selection in communication networks are disclosed. Example route selection methods disclosed herein include: mapping performance measurements corresponding to network components to performance parameters to form mapped performance parameters, the network components being in at least one of a first candidate path and a second candidate path between a first network node and a second network node; calculating, based on the mapped performance parameters, first relative performance parameters for the network components, the first relative performance parameters corresponding to one or more services; calculating, based on the first relative performance parameters, second relative performance parameters for the respective candidate paths, the second relative performance parameters corresponding to one or more of the services; and, based on the second relative performance parameters, routing first service data corresponding to a first of the services on the first candidate path and routing second service data corresponding to a second of the services on the second candidate path.
