Method and system for controlling subscriber access in a network capable of establishing connections with a plurality of domain sites

Abstract

A method for controlling subscriber access in a network capable of establishing connections with a plurality of domains includes receiving a communication from a subscriber using a first communication network coupled to at least one other communication network, the communication optionally including a domain identifier associated with a domain on the at least one other communication network, determining whether the subscriber is authorized to access the domain based upon the domain identifier and a list of authorized domains for a virtual circuit used to receive the communication and authorizing subscriber access to the domain when the domain identifier is included in the list. An access server includes a tunnel ID request generator and an authorizer. The tunnel ID request generator generates a tunnel ID request that includes a virtual circuit identifier associated with a virtual circuit used to accept a PPP authentication request. The authorizer grants subscribers domain access based upon a list of authorized domains for the virtual circuit.
