In this paper, resource allocation strategies in QoS-routed optical networks are proposed. We particularly focus on one QoS-routing approach, where various quality attributes, like transmission performance or blocking probability, directly influence the cost functions of the so-called transformed network graph. In this graph, the new nodes are derived from the network elements relevant to the decisions on quality for a certain user. The costs for the graph edges are compound functions of that quality and the particular resource allocation strategy, like least-quality resource allocation, wavelength shifting minimisation, or alternate routing for multi-wavelength network resources. Numerical results for multi-service optical networks have shown that the QoS-based resource allocation can simultaneously accommodate particular user requirements, blocking probability and traffic dynamics
