Service Function Chaining (SFC)has gained momentum inthewakeofthe emergence of promising technologies suchas Network Function Virtualization (NFV), and Software Defined Networking (SDN). Many research works have explored Service Function Chaining under different aspects: composition, resource allocation, aswellas placement and chaining. However, SFC mapping ina multi-domain context with limited visibility onthe underlying infrastructure isstilIa challenging research topic. In this work, wemodelthe multi-domain SFC placement problem asa multi-objective ILP, then propose a scalable memetic algorithm. The efficiencyof our solution is evaluated by comparing its results totheones obtained from the exact solution withfull visibility onthe network topology.
