Abstract
Systems and methods for mapping service function chains to physical network resources include receiving a service function chain request specifying multiple service functions including a service access point, generating a service graph including service links between consecutive service functions, receiving resource information describing capabilities of physical network resources and a topology of the physical network, generating a resource graph including infra links between pairs of connected physical network resources, creating, dependent on the service graph and the resource graph, multiple solutions for mapping the service functions to the physical network resources, and outputting one or more mapping solutions. Each of generating the service graph, generating the resource graph, and creating the mapping solutions may be performed by one or instances of respective microservices that operate in parallel. The systems may also include respective microservice instances for creating end point mappings, creating infra node mappings, and pruning and ranking mapping solutions.
