A device-implemented network with domains each having nodes, the nodes of each of the domains sharing network information with one another according to an intra-domain communication policy. An inter-domain protocol is configured to control communication between at least one of the nodes of one of the domains and at least one of the nodes of a different one of the domains. A broker is configured to be communicatively coupled to the nodes and configured to control communication according to the inter-domain protocol and to which all of the nodes of each of the plurality of domains are configured to send the network information.
