A service partitions a service function chain (SFC) into multiple virtualized network functions (VNFs). The services deploys the VNFs to a smart contract operating in a distributed ledger. The smart contract initiates a bid to service the SFC. Multiple infrastructure providers (InPs) are identified and included in a graph structure. The graph is organized to reflect the order by which the VNFs are to be serviced by the different InPs. The graph also lists the costs the InPs require to service the various different VNFs. The InPs included in a specific graph traversal having the smallest cost are selected, but the cost that is used is the cost for the graph traversal having the penultimate smallest cost. The service outputs the selected InPs as well as the penultimate smallest cost.
