Abstract:
1. A method for providing computer network access, comprising: receiving a PPP session creation request from a client, said PPP session creation request including a control protocol frame encapsulated therein; obtaining user domain information associated with said PPP session creation request; setting up a Layer 2 tunnel for said client according to a parameter contained in said control protocol frame; creating an ingress PPP object associated with an incoming PPP session, a host object associated with said client, and an egress PPP object associated with said Layer 2 tunnel; creating an egress IP object based upon obtained user domain information, said egress IP object associated with IP-based forwarding; linking said ingress PPP object, said host object, and said egress PPP object, thereby forwarding data packets from a PPP session with said client over said Layer 2 tunnel; and linking said host object and said egress IP object, thereby forwarding IP frames received from said client over a link other than said Layer 2 tunnel.
