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.

Claims

1. A method for determining the domain name associated with virtual circuit, the method comprising:

receiving, at an Authentication, Authorization, and Accounting (AAA) server, a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

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;

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.

2. The method of claim 1 wherein the domain configuration override attribute is for use in determining whether a network service subscriber is limited to establishing a tunnel with a particular domain.

3. A method for determining the tunnel ID associated with virtual circuit, the method comprising:

receiving, at an Authentication, Authorization, and Accounting (AAA) server, a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

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;

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 tunnel ID 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.

4. The method of claim 3 wherein the domain configuration override attribute is for use in determining whether a network service subscriber is limited to establishing a tunnel with a particular domain.

5. An apparatus for determining the domain name associated with virtual circuit, the apparatus comprising:

means for receiving a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

means for 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;

means for, 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

means for, 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.

6. An apparatus for determining the tunnel ID associated with virtual circuit, the apparatus comprising:

means for receiving, at an Authentication, Authorization, and Accounting (AAA) server, a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

means for 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;

means for, if the domain configuration override attribute exists in the aid virtual circuit profile or if the PPP authentication request does not comprise a domain name, returning a tunnel ID associated with the unique identifier; and

means for, 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.

7. An Authentication, Authorization, and Accounting (AAA) server for determining the domain name associated with virtual circuit, the AAA server comprising:

a memory; and

a processor adapted to;

receive a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

determine whether a domain configuration override attribute exists in a virtual circuit profile associated with a DSLAM port used to receive the PPP authentication request;

if the domain configuration override attribute exists in the virtual circuit profile or if the PPP authentication request does not comprise a domain name, return a domain name associated with the unique identifier; and

if the domain configuration override attribute does not exist in the virtual circuit profile, return a PPP domain name used in the PPP authentication request.

8. An Authentication, Authorization, and Accounting (AAA) server for determining the tunnel ID associated with virtual circuit, the AAA server comprising:

a memory; and

a processor adapted to;

receive a Point-to-Point Protocol (PPP) authentication request comprising a unique identifier, the unique identifier comprising a virtual channel ID;

determine whether a domain configuration override attribute exists in a virtual circuit profile associated with a DSLAM port used to receive the PPP authentication request;

if the domain configuration override attribute exists in the virtual circuit profile or if the PPP authentication request does not comprise a domain name, return a tunnel ID associated with the unique identifier; and

if the domain configuration override attribute does not exist in the virtual circuit profile, return a PPP domain name used in the PPP authentication request.
