Abstract: Determining the domain name associated with a virtual circuit may includes receiving, at an Authentication, Authorization, and Accounting (AAA) server, a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier comprising a virtual channel ID, and determining whether a domain configuration override attribute exists in a virtual circuit profile associated with a DSLAM port used to receive the PPP authentication request. Determining the domain name further includes, if the domain configuration override attribute exists in the virtual circuit profile or if the PPP authentication request does not comprise a domain name, returning a domain name associated with the unique identifier, and if the domain configuration override attribute does not exist in the virtual circuit profile, returning a PPP domain name used in the PPP authentication request.

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.

Abstract: A method for controlling subscriber access in a network capable of establishing connections with multiple services includes receiving a communication from a subscriber using a first communication network coupled to a second communication network, the communication optionally including a domain identifier associated with a service on the second communication network, and authorizing the subscriber to access a service on the second communication network using a virtual circuit. The authorization is based upon a domain configuration override attribute associated with the virtual circuit used to receive the communication from the subscriber.
