SFCs) in the physical network. In doing so, the provider must balance between various competing goals of performance and resource usage.  ...  A service provider utilizing NFV technology faces the SFC provisioning problem of assigning VNF instances to nodes in the physical infrastructure (e.g., a datacenter), and routing Service Function Chains  ...  Combined, these three elements create our Stringer system that generates a set of SFC provisioning solutions varying in resource usage and performance.  ...
