Abstract: In some examples, a method includes parsing, by a network device, a set of flow rules and network function configurations to identify an equivalent class of packets passing through network function chains; identifying, by the network device, a plurality of paths that packets belonging to the equivalent class pass through; computing, by the network device, a first set of Service Level Agreement (SLA) performance metrics for the equivalent class; constructing, by the network device, a set of stateful forwarding criteria comprising the first set of SLA performance metrics; and verifying, by the network device, whether the network function chains comply with a SLA based on the stateful forwarding criteria.
