A method and apparatus for partitioning network data services among multiple subscribers uses information stored in several tables to define a plurality of independent networks where each independent network comprises a set of access ports and a unique set of destination addresses and is logically separate from all other independent networks so that no information can pass from one independent network to another independent network. When a subscriber makes a request to use an independent network, a subscriber key that is based on the subscriber identity and the network access port is used to determine whether the subscriber has permission to use the independent network. If the subscriber has permission to use the independent network, information retrieved from the tables is used to determine whether the source subscriber or a destination subscriber has control over the resource. If a destination subscriber has control over the resource, using information in the request to identify a destination subscriber and a response port; and if the source subscriber has control over the resource, using the identity to determine whether the source subscriber can access the resource.
