Software Defined Networks (SDN) heavily rely on diverse management rules (ACL, traffic control, etc. ) to satisfy security and business requirements of their associated services. As these networks are increasing in size and complexity, their management rules configured in devices are becoming more complex. These rules are constantly growing in size and it is challenging to distribute them across network devices with limited capacities. The most challenging task is to deploy rules updates in a fast and efficient way to avoid a security breach or to meet a service needs. In this paper, we extend our previous work on network management rules distribution by introducing an efficient update strategy. Through extensive experiments on several rule sets with single and multiple path topologies, we evaluate and analyze the performance of our strategy. Our obtained results show a reduction of up to 90% in update time.
