Self-Configuring Network Devices

An IT (Information Technology) structure is defined as any combination of hardware, software, networking, services, and labor, and relationships among these entities, and is represented by an object model. The object model includes generation functions, including ability to generate firewall and load balancing rules.

Upon installation of a firewall or load-balancer, the self-configuration software is invoked and performs the process described in the Figure 1. The process starts by performing discovery of the network and creation of an IT structure model 101. Once the IT structure model is created, the appropriate configuration generator function (for a stateful firewall or a load-balancer) is invoked to generate the firewall rules or load-balancing configuration 102. The generated set of firewall rules or a load-balancing configuration is then applied to the network device 103.

The process may be invoked again manually to refresh the rules, should the network configuration change.

The process may also be invoked on a periodic basis, or, for a firewall, as a consequence of a new entity attempting a communication through the network.
