Abstract
A method and device for communicating information resources between subscriber end stations and nodes belonging to different network domains is described. The device instantiates different virtual network machines for different network domains using separate independently administrable network databases. Each of the administrable chores of the separate independently administrable network databases includes the assignment of access control and the configuration of the policies for those network databases. The policies include traffic filtering policies to indicate what kind of information payloads can be carried, traffic and route filtering policies to indicate what paths through the network will be used for each payload carried. Each of the network domains includes one of the different virtual network machines and each of the different network domains is virtually isolated from other network domains.
