More Information
Summary:A software-defined network (SDN) rule modification counter system provides counters that track all changes and edits to rules at SDN controllers and SDN switches on an SDN. The system compares counters at the SDN controller and SDN switch to determine if they match. If the counters do not match, a change has been made to the rules. With the addition of rule edit statistics the SDN controller will now have visibility that a rule modification was performed. The SDN controller then verifies that the state of the device is the same as its expected state as a secondary integrity check. Based on the rule modification notification, changes to a central rules table at the SDN controller and changes to rule settings at the SDN switch are made according to pre-programmed logic.
