Abstract

Nodes of a protected system perform protected network address discovery by establishing a management overlay network using static network addresses not subject to network discovery, and using the overlay network to communicate application-level network address information among the protected nodes. Each protected node operates to (1) maintain a store of the application-level network address information from the overlay network, and instantiate protective packet filters at node ports, and (2) in response to an outgoing network address discovery request, (a) use a packet filter to consult the store and retrieve target network address information for a target of the discovery request, and (b) make an on-node response with the target network address information without forwarding the discovery request out to the substrate network. Network discovery is thus protected from the effects of potential network address conflicts involving the other nodes, which may be outside the control of the protected system.
