Abstract
In some examples, a system obtains a network logical model and, for each node in a network, a node-level logical, concrete, and hardware model. The system identifies a service function chain, and determines a respective set of service function chain rules. For each node, the system determines whether the respective set of service function chain rules is correctly captured in the node-level logical model and/or concrete model to yield a node containment check result. Based on a comparison of policy actions in the concrete model, hardware model, and at least one of the node-level logical model or network logical model, the system determines whether the respective set of service function chain rules is correctly rendered on each node to yield a node rendering check result. Based on the node containment check result and node rendering check result, the system determines whether the service function chain is correctly configured.
