Abstract: A computing system and a method are provided for determining a network traffic routing path through a service function chain (SFC). A joint network slicing and traffic engineering problem is provided that may be solved to identify network slicing configuration and traffic engineering parameters to provide a set of function nodes, the SFC, and the network traffic routing path from the source node to the destination node. The joint network slicing and traffic engineering problem P may be solved by minimizing a resource objective associated with the joint network slicing and traffic engineering problem, in accordance with a set of one or more constraints. Instructions may be transmitted to a network orchestrator to create the service function chain in a network slice on the set of network nodes in accordance with the identified network slicing configuration and traffic engineering parameters, to provide the network traffic routing path.
