Abstract

In a first aspect of the present invention, a Wholesaler dynamically identifies one of a plurality of AAA services at a remote domain to route an access request to. The AAA service is selected based upon a set of rules applied to information which has been received dynamically from the plurality of AAA services and is indicative of load and status of the plurality of AAA services. In a second aspect of the present invention, a Wholesaler, based upon a Service Level Agreement (SLA) between the Wholesaler and a user, routes the user to one of a plurality of sub-service providers.

Claims

1. A method for managing network access requests to a data communications network, said method comprising:

receiving at a point of presence (PoP) of the data communications network a network access request from a user the domain of which is not the same as that of the PoP;

forwarding the network access request to a proxy service at the PoP;

determining the user'"'"'s domain;

looking up information regarding a plurality of authentication, authorization and accounting (AAA) services associated with the user'"'"'s domain;

checking the information to determine which of the plurality of AAA services associated with the user'"'"'s domain are available;

selecting an available AAA service associated with the user'"'"'s domain; and

proxying an access request to said selected AAA service.
